Native defects in tetradymite Bi2(TexSe3-x) topological insulators  

SciTech Connect (OSTI)

Formation energies of native defects in Bi2(TexSe3-x), with comparison to ideal Bi2Te2S, are calculated in density-functional theory to assess transport properties. Bi2Se3 is found to be n type for both Bi- and Se-rich growth conditions, while Bi2Te3 changes from n to p type going from Te- to Bi-rich conditions, as observed. Bi2Te2Se and Bi2Te2S are generally n type, explaining observed heavily doped n-type behavior in most samples. A (0/-) transition level at 16 meV above valence-band maximum for Bi on Te antisites in Bi2Te2Se is related to the observed thermally active transport gap causing a p-to-n transition at low temperature. Bi2(TexSe3-x) with x>2 are predicted to have high bulk resistivity due to effective carrier compensation when approaching the n-to-p crossover. Predicted behaviors are confirmed from characterization of our grown single crystals.

Three-dimensional topological insulators Bi{sub 2}Te{sub 3}, Bi{sub 2}Se{sub 3}, and Bi{sub 2}Te{sub 2}Se - a microwave spectroscopy study  

SciTech Connect (OSTI)

We present results of investigations of three-dimensional topological insulators from a family of bismuth compounds performed in electron spin resonance spectrometer. Next to the standard spin resonance spectra in Bi{sub 2}Se{sub 3} originating from bulk conduction electrons (g{sub Verbar;} = 27.5 ± 0.1 and g{sub ?} = 19.5 ± 0.1), we observed also cyclotron resonance due to topological surface states in Bi{sub 2}Te{sub 3} and non-resonant signal related to weak anti-localization in Bi{sub 2}Te{sub 2}Se. The analysis of the cyclotron resonance signal yields low Fermi velocity equal to 3250 m/s in Bi{sub 2}Te{sub 3}. The phase coherence length determined from weak anti-localization signal equals to 550 nm at low temperatures in Bi{sub 2}Te{sub 2}Se. Relation of the signals to bulk, topological surface or two-dimensional quantum well states is discussed and where possible indicated.

Topological insulator Bi 2 Se 3 thin films grown on double-layer graphene by molecular beam epitaxy  

Science Journals Connector (OSTI)

Atomically flat thin films of topological insulator Bi 2 Se 3 have been grown on double-layer graphene formed on 6H–SiC(0001) substrate by molecular beam epitaxy. By a combined study of reflection high energy electron diffraction and scanning tunneling microscopy we identified the Se-rich condition and temperature criterion for layer-by-layer growth of epitaxial Bi 2 Se 3 films. The as-grown films without doping exhibit a low defect density of 1.0 ± 0.2 × 10 11 / cm 2 and become a bulk insulator at a thickness of ten quintuple layers as revealed by in situ angle resolved photoemission spectroscopy measurement.

Electric tuning of the surface and quantum well states in Bi2Se3 films: a first-principles study  

SciTech Connect (OSTI)

Based on first-principles calculations in the framework of van der Waals density functional theory, we find that giant, Rashba-like spin splittings can be induced in both the surface states and quantum well states of thin Bi2Se3 films by application of an external electric field. The charge is redistributed so that the Dirac cones of the upper and lower surfaces become nondegenerate and completely gapless. Interestingly, a momentum-dependent spin texture is developed on the two surfaces of the films. Some of the quantum well states, which reside in the middle of the Bi2Se3 film under zero field, are driven to the surface by the electric field. The Rashba splitting energy has a highly non-linear dependence on the momentum and the electric field due to the large contribution of the high-order Rashba terms, which suggests complex spin dynamics in the thin films of Bi2Se3 under an electric field.

Observations of two-dimensional quantum oscillations and ambipolar transport in the topological insulator Bi2Se3 achieved by Cd doping  

Science Journals Connector (OSTI)

We present a defect-engineering strategy to optimize the transport properties of the topological insulator Bi2Se3 to show a high bulk resistivity and clear quantum oscillations. Starting with a p-type Bi2Se3 obtained by combining Cd doping and a Se-rich crystal-growth condition, we were able to observe a p-to-n-type conversion upon gradually increasing the Se vacancies by post annealing. With the optimal annealing condition, where a high level of compensation is achieved, the resistivity exceeds 0.5 ?cm at 1.8 K and we observed two-dimensional Shubnikov–de Haas oscillations composed of multiple frequencies in magnetic fields below 14 T.

Comparison of crystal growth and thermoelectric properties of n-type Bi-Se-Te and p-type Bi-Sb-Te nanocrystalline thin films: Effects of homogeneous irradiation with an electron beam  

SciTech Connect (OSTI)

The effects of homogenous electron beam (EB) irradiation on the crystal growth and thermoelectric properties of n-type Bi-Se-Te and p-type Bi-Sb-Te thin films were investigated. Both types of thin films were prepared by flash evaporation, after which homogeneous EB irradiation was performed at an acceleration voltage of 0.17?MeV. For the n-type thin films, nanodots with a diameter of less than 10?nm were observed on the surface of rice-like nanostructures, and crystallization and crystal orientation were improved by EB irradiation. The resulting enhancement of mobility led to increased electrical conductivity and thermoelectric power factor for the n-type thin films. In contrast, the crystallization and crystal orientation of the p-type thin films were not influenced by EB irradiation. The carrier concentration increased and mobility decreased with increased EB irradiation dose, possibly because of the generation of defects. As a result, the thermoelectric power factor of p-type thin films was not improved by EB irradiation. The different crystallization behavior of the n-type and p-type thin films is attributed to atomic rearrangement during EB irradiation. Selenium in the n-type thin films is more likely to undergo atomic rearrangement than the other atoms present, so only the crystallinity of the n-type Bi-Se-Te thin films was enhanced.

Spectroscopic ellipsometric modeling of a Bi–Te–Se write layer of an optical data storage device as guided by atomic force microscopy, scanning electron microscopy, and X-ray diffraction  

Science Journals Connector (OSTI)

Abstract Conventional magnetic tape is the most widely used medium for archival data storage. However, data stored on it need to be migrated every ca. 5 years. Recently, optical discs that store information for hundreds, or even more than 1000 years, have been introduced to the market. We recently proposed that technology in these optical discs be used to make an optical tape that would show greater permanence than its magnetic counterpart. Here we provide a detailed optical characterization of a sputtered thin film of bismuth, tellurium, and selenium (BTS) that is a proposed data storage layer for these devices. The methodology described herein should be useful in the future development of related materials. Spectroscopic ellipsometry (SE) data are obtained using interference enhancement, and the modeling of this data is guided by results from atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray reflectivity (XRR). By AFM, ca. 40 nm BTS films show ca. 10 nm roughness. SEM images also suggest considerable roughness in the films and indicate that they are composed of 13.1 ± 5.9 nm grains. XRD confirms that the films are crystalline and predicts a grain size of 17 ± 2 nm. XRD results are consistent with the composition of the films — a mildly oxidized BTS material. Three models of increasing complexity are investigated to explain the SE data. The first model consists of a smooth, homogeneous BTS film. The second model adds a roughness layer to the previous model. The third model also has two layers. The bottom layer is modeled as a mixture of BTS and void using a Bruggeman effective medium approximation. The upper layer is similarly modeled, but with a gradient. The first model was unable to adequately model the SE data. The second model was an improvement — lower MSE (4.4) and good agreement with step height measurements. The third model was even better — very low MSE (2.6) and good agreement with AFM results. The third SE model predicted ca. 90% void at the film surface. XRR modeling of the film agreed well with the predictions from SE. The uniquenesses of the SE models were confirmed.

Method of producing superconducting fibers of bismuth strontium calcium copper oxide (Bi(2212) and Bi(2223))  

DOE Patents [OSTI]

Fibers of Bi(2212) have been produce by pendant drop melt extraction. This technique involves the end of a rod of Bi(2212) melted with a hydrogen-oxygen torch, followed by lowering onto the edge of a spinning wheel. The fibers are up to 15 cm in length with the usual lateral dimensions, ranging from 20 um to 30 um. The fibers require a heat treatment to make them superconducting.

Metallurgy, thermal stability, and failure mode of the commercial Bi-Te-based thermoelectric modules.  

SciTech Connect (OSTI)

Bi-Te-based thermoelectric (TE) alloys are excellent candidates for power generation modules. We are interested in reliable TE modules for long-term use at or below 200 C. It is known that the metallurgical characteristics of TE materials and of interconnect components affect the performance of TE modules. Thus, we have conducted an extensive scientific investigation of several commercial TE modules to determine whether they meet our technical requirements. Our main focus is on the metallurgy and thermal stability of (Bi,Sb){sup 2}(Te,Se){sup 3} TE compounds and of other materials used in TE modules in the temperature range between 25 C and 200 C. Our study confirms the material suite used in the construction of TE modules. The module consists of three major components: AlN cover plates; electrical interconnects; and the TE legs, P-doped (Bi{sub 8}Sb{sub 32})(Te{sub 60}) and N-doped (Bi{sub 37}Sb{sub 3})(Te{sub 56}Se{sub 4}). The interconnect assembly contains Sn (Sb {approx} 1wt%) solder, sandwiched between Cu conductor with Ni diffusion barriers on the outside. Potential failure modes of the TE modules in this temperature range were discovered and analyzed. The results show that the metallurgical characteristics of the alloys used in the P and N legs are stable up to 200 C. However, whole TE modules are thermally unstable at temperatures above 160 C, lower than the nominal melting point of the solder suggested by the manufacture. Two failure modes were observed when they were heated above 160 C: solder melting and flowing out of the interconnect assembly; and solder reacting with the TE leg, causing dimensional swelling of the TE legs. The reaction of the solder with the TE leg occurs as the lack of a nickel diffusion barrier on the side of the TE leg where the displaced solder and/or the preexisting solder beads is directly contact the TE material. This study concludes that the present TE modules are not suitable for long-term use at temperatures above 160 C due to the reactivity between the Sn-solder and the (Bi,Sb){sup 2}(Te,Se){sup 3} TE alloys. In order to deploy a reliable TE power generator for use at or below 200 C, alternate interconnect materials must be used and/or a modified module fabrication technique must be developed.

Concentrations of /sup 207/Bi and /sup 210/Pb-/sup 210/Bi-/sup 210/Po disequilibrium in fish  

SciTech Connect (OSTI)

Radioactive /sup 207/Bi, produced during nuclear testing at the Pacific Proving Grounds, concentrates in the muscle tissue and organs of goatfish and certain pelagic lagoon fish from Bikini and Enewetak Atolls. It is reasonable to expect that fish capable of accumulating /sup 207/Bi could also be efficient accumulators of other bismuth isotopes - namely /sup 210/Bi, the daughter of naturally occurring /sup 210/Pb. Therefore, /sup 210/Bi and consequently /sup 210/Po, the decay product of /sup 210/Bi, would be expected in notable excess over the precursor /sup 210/Pb in specific tissues. To test this assumption, we compared concentrations of /sup 210/Pb, /sup 210/Bi, and /sup 210/Po in muscle, liver, and bone separated from some reef species from the Marshall Islands. Concentrations of /sup 210/Bi in muscle and liver were found to exceed those of its precursor by factors of 2 to 15. The excess /sup 210/Bi in some species, however, is not from the environmental sources (either food or water) from which /sup 207/Bi is derived. The data suggest that the excess /sup 210/Bi may be translocated to muscle and liver tissue following the decay of /sup 210/Pb in bone.

Bi3+ Luminescence in ABiO2Cl (A = Sr, Ba) and BaBiO2Br  

SciTech Connect (OSTI)

Trivalent bismuth luminescence is reported in three Sillenbismuth oxyhalide phases, SrBiO2Cl, BaBiO2Cl, and BaBiO2Br. Thesecompounds exhibit Bi 6s6->6 s2 emission under UV and X-ray radiation.At room temperature, BaBiO2Cl shows the most intense light emission, withspectral and decay properties similar to those found in Bi4Ge3O12 (BGO).At low temperatures, each phase show an increase in the photoluminescenceintensities and a narrowing of the emission peaks. In contrast to thetemperature dependence of BGO, X-ray excited luminescence intensities ofall three phases remain relatively constant throughout the temperaturerange 10 - 295 K. This result indicates that the Sillen phases undergoless thermal quenching than BGO. The low temperature and room temperatureradio-luminescence decay times were determined from pulsed x-raymeasurements. At room temperature, SrBiO2Cl exhibits faster decays thanBGO, while, BaBiO2Cl and BaBiO2Br have decay times similar toBGO.

Bi-metric Gravity and "Dark Matter"  

E-Print Network [OSTI]

We present a bi-metric theory of gravity containing a length scale of galactic size. For distances less than this scale the theory satisfies the standard tests of General Relativity. For distances greater than this scale the theory yields an effective gravitational constant much larger than the locally observed value of Newton's constant. The transition from one regime to the other through the galactic scale can explain the observed rotation curves of galaxies and hence the effects normally attributed to the presence of dark matter. Phenomena on an extragalactic scale such as galactic clusters and the expansion of the universe are controlled by the enhanced gravitational coupling. This provides an explanation of the missing matter normally invoked to account for the observed value of Hubble's constant in relation to observed matter.

Thermal stability of MnBi magnetic materials  

SciTech Connect (OSTI)

MnBi has attracted much attention in recent years due to its potential as a rare-earth-free permanent magnet material. It is unique because its coercivity increases with increasing temperature, which makes it a good hard phase material for exchange coupling nanocomposite magnets. MnBi phase is difficult to obtain, partly because the reaction between Mn and Bi is peritectic, and partly because Mn reacts readily with oxygen. MnO formation is irreversible and harmful to magnet performance. In this paper, we report our efforts toward developing MnBi permanent magnets. To date, high purity MnBi (>90%) can be routinely produced in large quantities. The produced powder exhibits 74:6 emu g1 saturation magnetization at room temperature with 9 T applied field. After proper alignment, the maximum energy product (BH) max of the powder reached 11.9 MGOe, and that of the sintered bulk magnet reached 7.8 MGOe at room temperature. A comprehensive study of thermal stability shows that MnBi powder is stable up to 473 K in air.

The Nuclear Moments of Se79  

Science Journals Connector (OSTI)

Microwave measurements of the J=2?3 rotational transition of OCSe containing the radioactive-nucleus Se79 have established the Se79 spin as 72 and the Se79 quadrupole moment as 0.7×10-24 cm2±20 percent. The quadrupole coupling constant eqQ is 752.09±0.05 Mc/sec. The magnetic moment of Se79 has been determined as -1.015±0.015 nuclear magnetons by observation of the Zeeman splitting of one hyperfine component. The 72 spin and the large positive Q are inconsistent with the single-particle nuclear-shell model, but suggest the configuration (g92)272. This assignment is substantiated by the negative magnetic moment.Measurement of isotopic shifts gives a value for the Se79 mass, and an odd-even mass difference of 2.4 millimass units for this nucleus.

Thermoelectric transport properties of CaMg2Bi2, EuMg2Bi2, and YbMg2Bi2  

SciTech Connect (OSTI)

The thermoelectric transport properties of CaMg{sub 2}Bi{sub 2}, EuMg{sub 2}Bi{sub 2}, and YbMg{sub 2}Bi{sub 2} were characterized between 2 and 650 K. As synthesized, the polycrystalline samples are found to have lower p-type carrier concentrations than single-crystalline samples of the same empirical formula. These low carrier concentration samples possess the highest mobilities yet reported for materials with the CaAl{sub 2}Si{sub 2} structure type, with a mobility of {approx}740 cm{sup 2}/V/s observed in EuMg{sub 2}Bi{sub 2} at 50 K. Despite decreases in the Seebeck coefficient ({alpha}) and electrical resistivity ({rho}) with increasing temperature, the power factor ({alpha}{sup 2}{rho}) increases for all temperatures examined. This behavior suggests a strong asymmetry in the conduction of electrons and holes. The highest figure of merit (zT) is observed in YbMg{sub 2}Bi{sub 2}, with zT approaching 0.4 at 600 K for two samples with carrier densities of approximately 2 x 10{sup 18} cm{sup -3} and 8 x 10{sup 18} cm{sup -3} at room temperature. Refinements of neutron powder diffraction data yield similar behavior for the structures of CaMg{sub 2}Bi{sub 2} and YbMg{sub 2}Bi{sub 2}, with smooth lattice expansion and relative expansion in c being {approx}35% larger than relative expansion in a at 973 K. First-principles calculations reveal an increasing band gap as Bi is replaced by Sb and then As, and subsequent Boltzmann transport calculations predict an increase in {alpha} for a given n associated with an increased effective mass as the gap opens. The magnitude and temperature dependence of {alpha} suggests higher zT is likely to be achieved at larger carrier concentrations, roughly an order of magnitude higher than those in the current polycrystalline samples, which is also expected from the detailed calculations.

Nonlinear excitations in Debye bi-crystals  

SciTech Connect (OSTI)

The nonlinear dynamics of longitudinal dust lattice waves propagating in a dusty plasma bi-crystal is investigated. A ''diatomic''-like one-dimensional dust lattice configuration is considered, consisting of two distinct dust grain species with different charges and masses. Two different frequency dispersion modes are obtained in the linear limit, namely, an optical and an acoustic wave dispersion branch. Nonlinear solitary wave solutions are shown to exist in both branches, by considering the continuum limit for lattice excitations in different nonlinear potential regimes. For this purpose, a generalized Boussinesq and an extended Korteweg de Vries equation is derived, for the acoustic mode excitations, and their exact soliton solutions are provided and compared. For the optic mode, a nonlinear Schroedinger-type equation is obtained, which is shown to possess bright- (dark-) type envelope soliton solutions in the long (short, respectively) wavelength range. Optic-type longitudinal wavepackets are shown to be generally unstable in the continuum limit, though this is shown not to be the rule in the general (discrete) case.

High Performance of InSe and InSeGraphene Heterostructure Based Wide Spectral Photodetectors  

E-Print Network [OSTI]

We investigated both the few-layered InSe/metal photodetectors and InSe/graphene heterostructure photodetectors. Both types of the photodetectors show broad spectral range at 400-1000 nm. The few-layered InSe/metal photodetectors have higher photoresponsivity than that of the InSe/graphene heterostructure photodetectors. However, the InSe/graphene heterostructure photodetectors possesses a fast response time down to 100 {\\mu}s, which is about 40 times faster than that of the InSe/metal devices. The design of 2D crystal/graphene heterostructure could be important for high performace optoelectronic devices.

Oxygen resonance is observed, demonstrating the existence of empty O 2p states. These results support a more covalent rather than a simple ionic picture for the electronic states of BaBiO{sub 3}. 10 refs., 2 figs.

Variation of lattice constant and cluster formation in GaAsBi  

SciTech Connect (OSTI)

We investigate the structural properties of GaAsBi layers grown by molecular beam epitaxy on GaAs at substrate temperatures between 220–315 °C. Irrespective of the growth temperature, the structures exhibited similar Bi compositions, and good overall crystal quality as deduced from X-Ray diffraction measurements. After thermal annealing at temperatures as low as 500 °C, the GaAsBi layers grown at the lowest temperatures exhibited a significant reduction of the lattice constant. The lattice variation was significantly larger for Bi-containing samples than for Bi-free low-temperature GaAs samples grown as a reference. Rutherford backscattering spectrometry gave no evidence of Bi diffusing out of the layer during annealing. However, dark-field and Z-contrast transmission electron microscopy analyses revealed the formation of GaAsBi clusters with a Bi content higher than in the surrounding matrix, as well as the presence of metallic As clusters. The apparent reduction of the lattice constant can be explained by a two-fold process: the diffusion of the excess As incorporated within As{sub Ga} antisites to As clusters, and the reduction of the Bi content in the GaAs matrix due to diffusion of Bi to GaAsBi clusters. Diffusion of both As and Bi are believed to be assisted by the native point defects, which are present in the low-temperature as-grown material.

Phase stability, structures and properties of the (Bi{sub 2}){sub m} (Bi{sub 2}Te{sub 3}){sub n} natural superlattices  

SciTech Connect (OSTI)

The phase stability of the (Bi{sub 2}){sub m} (Bi{sub 2}Te{sub 3}){sub n} natural superlattices has been investigated through the low temperature solid state synthesis of a number of new binary Bi{sub x}Te{sub 1-x} compositions. Powder X-ray diffraction revealed that an infinitely adaptive series forms for 0.44{<=}x{<=}0.70, while an unusual 2-phase region with continuously changing compositions is observed for 0.41{<=}x{<=}0.43. For x>0.70, mixtures of elemental Bi and an almost constant composition (Bi{sub 2}){sub m} (Bi{sub 2}Te{sub 3}){sub n} phase are observed. Rietveld analysis of synchrotron X-ray powder diffraction data collected on Bi{sub 2}Te (m=2, n=1) revealed substantial interchange of Bi and Te between Bi{sub 2} and Bi{sub 2}Te{sub 3} blocks, demonstrating that the block compositions are variable. All investigated phase pure compositions are degenerate semiconductors with low residual resistivity ratios and moderate positive magnetoresistances (R/R{sub 0}=1.05 in 9 T). The maximum Seebeck coefficient is +80 {mu}V K{sup -1} for x=0.63, leading to an estimated thermoelectric figure of merit, zT=0.2 at 250 K. - Graphical abstract: An infinite number of possible (Bi{sub 2}){sub m} (Bi{sub 2}Te{sub 3}){sub n} structures exist for Bi{sub x}Te{sub 1-x} compositions between x=0.44 and x=0.70.

Anisotropy in CdSe quantum rods  

SciTech Connect (OSTI)

The size-dependent optical and electronic properties of semiconductor nanocrystals have drawn much attention in the past decade, and have been very well understood for spherical ones. The advent of the synthetic methods to make rod-like CdSe nanocrystals with wurtzite structure has offered us a new opportunity to study their properties as functions of their shape. This dissertation includes three main parts: synthesis of CdSe nanorods with tightly controlled widths and lengths, their optical and dielectric properties, and their large-scale assembly, all of which are either directly or indirectly caused by the uniaxial crystallographic structure of wurtzite CdSe. The hexagonal wurtzite structure is believed to be the primary reason for the growth of CdSe nanorods. It represents itself in the kinetic stabilization of the rod-like particles over the spherical ones in the presence of phosphonic acids. By varying the composition of the surfactant mixture used for synthesis we have achieved tight control of the widths and lengths of the nanorods. The synthesis of monodisperse CdSe nanorods enables us to systematically study their size-dependent properties. For example, room temperature single particle fluorescence spectroscopy has shown that nanorods emit linearly polarized photoluminescence. Theoretical calculations have shown that it is due to the crossing between the two highest occupied electronic levels with increasing aspect ratio. We also measured the permanent electric dipole moment of the nanorods with transient electric birefringence technique. Experimental results on nanorods with different sizes show that the dipole moment is linear to the particle volume, indicating that it originates from the non-centrosymmetric hexagonal lattice. The elongation of the nanocrystals also results in the anisotropic inter-particle interaction. One of the consequences is the formation of liquid crystalline phases when the nanorods are dispersed in solvent to a high enough concentration. The preparation of the stable liquid crystalline solution of CdSe nanorods is described, as well as the large-scale alignment of the nanorods by taking advantage of the long-range orientational correlation in the liquid crystals. In addition, we investigated the phase diagram of the nanorod solution, as a step toward understanding the possible role of the long-range attractive interaction between the nanorods in the formation of lyotropic liquid crystals.

Interstitial BiO molecule as a broadband IR luminescence centre in bismuth-doped silica glass  

SciTech Connect (OSTI)

Experimental data on absorption and luminescence in optical fibres with a Bi : SiO{sub 2} glass core are compared to experimentally determined and calculated spectroscopic properties of the BiO molecule. The results suggest that the IR luminescence of Bi : SiO{sub 2} glass is due to interstitial BiO molecules. This assumption is supported by quantum-chemical simulation results for a BiO molecule in a ring interstice of the silica glass network.

Magnetism of HgSe:Fe  

Science Journals Connector (OSTI)

The perpendicular and parallel components of the magnetization of the mixed valence system Hg1-xFexSe in the strongly dilute limit (xmagnetic fields up to 20 T. In this interesting semimagnetic semiconductor the overall magnetization is caused simultaneously by Fe3+ (Brillouin paramagnet), Fe2+ (van Vleck paramagnet), and free electrons (diamagnetic de Haas-van Alphen effect). Using a torque magnetometer the various contributions with their anisotropy are individually determined. For very low iron content (xmagnetic moment perpendicular to the magnetic field when applying the field in a nonsymmetric direction of the crystal. Using recent theoretical results on the energy-level diagram of Fe2+ in the Td symmetry of a HgSe host lattice we deduce a spin-orbit level splitting of 2 meV from our experimental data. In contrast to higher concentration samples, both the Brillouin paramagnetism of Fe3+ and the van Vleck paramagnetism of Fe2+ can be attributed to the sum from individual Fe donors with no obvious magnetic interaction between them. Finally, we also have measured de Haas-van Alphen oscillations of the conduction-band electrons with amplitudes of the same order as the paramagnetic background. From the measured crystal-field-induced anisotropy in the magnetic moment we deduce a Fermi-surface anisotropy of about 7%.

Structural and physical properties of BiVO{sub 3}  

SciTech Connect (OSTI)

We report the phase stabilization and properties of BiVO{sub 3} (BVO) thin films, grown on (001) SrTiO{sub 3} and LaAlO{sub 3}, using the pulsed laser deposition technique. Bi and V are in 3+ oxidation states as measured by using x-ray photoelectrons spectroscopy. BVO exhibits a Curie-Weiss paramagnetic behaviour and about ?26 K Weiss temperature. This demonstrates the presence of a strong correlation effect due to the spin fluctuation. Additionally, these films exhibit a semiconducting behaviour owing to the thermally activated conduction process. A plausible explanation of the observed properties is presented by comparing with the closely related LaVO{sub 3} and other orthovanadates.

Linear Transformations, Canonoid Transformations and BiHamiltonian Structures  

E-Print Network [OSTI]

We give a characterization of linear canonoid transformations on symplectic manifolds and we use it to generate biHamiltonian structures for some mechanical systems. Utilizing this characterization we also study the behavior of quadratic superintegrable systems under canonoid transformations. We present a description of canonoid transformations due to E.T. Whittaker, and we show that it leads, in a natural way, to the modern, coordinate-independent definition of canonoid transformations. We also generalize canonoid transformations to Poisson manifolds by introducing Poissonoid transformations. We give examples of such transformations for Euler's equations of the rigid body (on $ \\mathfrak{ so}^\\ast (3) $ and $ \\mathfrak{ so}^\\ast (4)$) and for an integrable case of Kirchhoff's equations for the motion of a rigid body immersed in an ideal fluid. We study the relationship between biHamiltonian structures and Poissonoid transformations for these examples.

It is shown that the phase with composition Bi{sub 2}S{sub 3} appears as result of consecutive deposition of Bi and S irrespective of the order of deposition; this phase also appears in the case of simultaneous deposition of components. The films formed at room temperature are amorphous. Amorphous thin Bi{sub 2}S{sub 3} films are stable at room temperature and crystallize at temperatures in the region of {approx}423 K. The conditions for formation of Bi{sub 2}S{sub 3} films with different substructures are established.

SciTech Connect (OSTI)

The band offsets of PbSe/Pb{sub 1-x}Eu{sub x}Se multi-quantum wells grown by molecular beam epitaxy are determined as a function of temperature and europium content using temperature-modulated differential transmission spectroscopy. The confined quantum well states in the valence and conduction bands are analyzed using a k{center_dot}p model with envelope function approximation. From the fit of the experimental data, the normalized conduction band offset is determined as 0.45{+-}0.15 of the band gap difference, independently of Eu content up to 14% and temperature from 20 to 300 K.

Photoinduced aging and viscosity evolution in Se-rich Ge-Se glasses  

SciTech Connect (OSTI)

We propose here to investigate the non-equilibrium viscosity of Ge-Se glasses under and after light irradiation. Ge{sub 10}Se{sub 90} and Ge{sub 20}Se{sub 80} fibers have been aged in the dark and under ambient light, over months. During aging, both the relaxation of enthalpy and the viscosity have been investigated. The viscosity was measured by shear relaxation-recovery tests allowing the measurement of non-equilibrium viscosity. When Ge{sub 10}Se{sub 90} glass fibers are aged under irradiation, a relatively fast fictive temperature decrease is observed. Concomitantly, during aging under irradiation, the non-equilibrium viscosity increases and reaches an equilibrium after two months of aging. This viscosity increase is also observed in Ge{sub 20}Se{sub 80} fibers. Nevertheless, this equilibrium viscosity is far below the viscosity expected at the configurational equilibrium. As soon as the irradiation ceases, the viscosity increases almost instantaneously by about one order of magnitude. Then, if the fibers are kept in the dark, their viscosity slowly increases over months. The analysis of the shear relaxation functions shows that the aging is thermorheologically simple. On the other side, there is no simple relaxation between the shear relaxation functions measured under irradiation and those measured in the dark. These results clearly suggest that a very specific photoinduced aging process occurs under irradiation. This aging is due to photorelaxation. Nevertheless, the viscosity changes are not solely correlated to photoaging and photorelaxation. A scenario is proposed to explain all the observed viscosity evolutions under and after irradiation, on the basis of photoinduced transient defects.

Structural properties of Bi-terminated GaAs(0 0 1) surface  

Science Journals Connector (OSTI)

Electronic and structural properties of Bi-terminated reconstructions on GaAs(0 0 1) surface have been studied by scanning tunneling microscopy (STM) and synchrotron radiation core-level spectroscopy. A 2–3 monolayer thick Bi-layer was evaporated on a Ga-terminated GaAs(0 0 1) surface. By heating the surface, the reconstruction changed from (2 × 1) to (2 × 4). The ?2 phase with one top Bi dimer and one As or Bi dimer in the third atomic layer per surface unit cell is proposed to explain the STM images of the Bi/GaAs(0 0 1)(2 × 4) surface heated at 400 °C. Bi 5d photoemission from the Bi/GaAs(2 × 4) consisted of two components suggesting two different bonding sites for Bi atoms on the (2 × 4) surface. The variation of the surface sensitivity of the photoemission induced no changes in the intensities of the components indicating that the origins of both components lie in the first surface layer.

Phase formation and phase transformations in Bi-Te films with nanoscale thickness  

SciTech Connect (OSTI)

The processes of phase formation are studied in a binary Bi-Te system using the kinematic electron diffraction technique. It is established that, in the case of both simultaneous and layer-by-layer deposition of bismuth and tellurium and irrespective of the order of their deposition, phases with compositions Bi{sub 2}Te{sub 3} and BiTe are formed at the condensation plane in the amorphous and crystalline state, respectively. The amorphous Bi{sub 2}Te{sub 3} phase is stable at room temperature and crystallizes at a temperature of 423 K. It is shown that ordering of the phase BiTe is not a consequence of atomic order of the structure; rather, it is caused by the real structure of the object (by blocks)

Temperature-dependent structure, elasticity, and entropic stability of Bi phases on Cu{111}  

Science Journals Connector (OSTI)

We have used low energy electron microscopy (LEEM) to characterize the structure and stability of Bi phases on Cu{111}. As a function of temperature we find that the Cu{111}(3×3)R30?-Bi surface alloy phase gradually dealloys and is fully depleted from Bi at a temperature of 803 K. The dealloying leads to a defect induced change of its elastic properties. The Bi surface alloy phase coexists with a Bi overlayer phase that exhibits a sharp decrease in density in a narrow temperature interval just below the temperature where the surface alloy phase has fully dealloyed. LEEM is used to directly evaluate the structure as well as the entropic contributions that determine the stability of each of the phases.

Computer Simulation of Diffusion of Pb-Bi Eutectic in Liquid Sodium by Molecular Dynamics Method  

SciTech Connect (OSTI)

Lead-bismuth eutectic is a potential candidate for coolant of secondary loops of sodium-cooled fast breeder reactors (FBR). The studies on the diffusion of liquid Pb-Bi in liquid Na are carried out corresponding to the case that liquid Pb-Bi leaks to liquid Na by accident. As the diffusion processes are the results of atomic motions, molecular dynamics method has been used to study the diffusion process. The self-diffusion coefficients of pure liquid Pb and Na, and liquid Pb-Bi are calculated and compared with ones by the empirical equations. The discrepancy between them could be eliminated by changing the densities of the liquids. The diffusion of lead-bismuth in sodium is simulated based on the changed densities under which the self-diffusion coefficients of individual liquid metals are close to those by the empirical equations. The simulation results show that the diffusion process of liquid Pb-Bi in liquid Na is a heat releasing process and the density of ternary liquid Na-Pb-Bi is higher than the average value of the densities of liquid Na and liquid Pb-Bi. It is also found that the diffusion coefficients of liquid Pb-Bi in liquid Na are much higher than their self-diffusion coefficients, indicating that liquid Pb-Bi are easy and quickly to diffuse in liquid Na. However, the diffusion coefficient of liquid Na is decreased due to the existence of liquid Pb-Bi, implying that liquid Na-Pb-Bi have a higher viscosity than that of pure liquid Na. (authors)

Effect of Composition and Heat Treatment on MnBi Magnetic Materials  

SciTech Connect (OSTI)

The metallic compound MnBi is a promising rare-earth-free permanent magnet material. Compare to other rare-earth-free candidates, MnBi stands out for its high intrinsic coercivity (Hci) and its large positive temperature coefficient. Several groups have demonstrated that the Hci of MnBi compound in thin film or in powder form can exceed 12 kOe and 26 kOe at 300 K and 523 K, respectively. Such steep increase in Hci with increasing temperature is unique to MnBi. Consequently, MnBi is a highly sought-after hard phase for exchange coupling nanocomposite magnets. The reaction between Mn and Bi is peritectic, so Mn tends to precipitate out of the MnBi liquid during the solidification process. As result, the composition of the Mn-Bi alloy with the largest amount of the desired LTP (low temperature phase) MnBi and highest saturation magnetization will be over-stoichiometric and rich in Mn. The amount of additional Mn required to compensate the Mn precipitation depends on solidification rate: the faster the quench speed, the less Mn precipitates. Here we report a systematic study of the effect of composition and heat treatments on the phase contents and magnetic properties of Mn-Bi alloys. In this study, Mn-Bi alloys with 14 compositions were prepared using conventional metallurgical methods such as arc melting and vacuum heat treatment, and the obtained alloys were analyzed for compositions, crystal structures, phase content, and magnetic properties. The results show that the composition with 55 at.% Mn exhibits the highest LTP MnBi content and the highest magnetization. The sample with this composition shows >90 wt.% LTP MnBi content. Its measured saturation magnetization is 68 emu/g with 2.3 T applied field at 300 K; its coercivity is 13 kOe and its energy product is 12 MGOe at 300 K. A bulk magnet fabricated using this powder exhibits an energy product of 8.2 MGOe.

Effects of Bi doping on the thermoelectric properties of ? -Zn 4 Sb 3  

Science Journals Connector (OSTI)

The thermoelectricproperties of Bi-doped compounds ( Zn 1 ? x Bi x ) 4 Sb 3 ( x = 0 0.0025 0.005 0.01 ) were studied experimentally as well as theoretically. The results indicate that low-temperature ( T 9975 Bi 0.0025 ) 4 Sb 3 reduces remarkably as compared with that of Zn 4 Sb 3 due to enhanced phonon scattering of impurity (dopant).Electrical resistivity and Seebeck coefficient increase monotonically with increase in the Bi content resulting mainly from decrease in carrier concentration. Moreover first-principle calculations were performed on the occupation options of Bi atoms in ? -Zn 4 Sb 3 which show that Bi will preferentially occupy the Zn sites and not Sb sites and act as donors being consistent with the experimental observations. In addition the lightly doped compound ( Zn 0.9975 Bi 0.0025 ) 4 Sb 3 exhibits the best thermoelectric performance due to the improvement in both its thermal conductivity and Seebeck coefficient whose figure of merit Z T is about 1.5 times larger than that of ? -Zn 4 Sb 3 at 300 K.

The metallic compound MnBi is a promising rare-earth-free permanent magnet material, unique among all candidates for its high intrinsic coercivity (Hci) and its large positive temperature coefficient. The Hci of MnBi in thin-film or powder form can exceed 12 and 26 kOe at 300 and 523 K, respectively. Such a steep rise in Hci with increasing temperature is unique to MnBi. Consequently, MnBi is a highly sought-after hard phase for exchange coupling nanocomposite magnets. However, the reaction between Mn and Bi is peritectic, and hence Mn tends to precipitate out of the MnBi liquid during the solidification process. As result, when the alloy is prepared using conventional induction or arc-melting casting methods, additional Mn is required to compensate the precipitation of Mn. In addition to composition, post-casting annealing plays an important role in obtaining a high content of MnBi low-temperature phase (LTP) because the annealing encourages the Mn precipitates and the unreacted Bi to react, forming the desired LTP phase. Here we report a systematic study of the effect of composition and heat treatments on the phase content and magnetic properties of Mn–Bi alloys. In this study, 14 compositions were prepared using conventional metallurgical methods, and the compositions, crystal structures, phase content and magnetic properties of the resulting alloys were analyzed. The results show that the composition with 55 at.% Mn exhibits both the highest LTP content (93 wt.%) and magnetization (74 emu g?1 with 9 T applied field at 300 K).

Evidence against a charge density wave on Bi(111)  

SciTech Connect (OSTI)

The Bi(111) surface was studied by scanning tunneling microscopy (STM), transmission electron microscopy (TEM) and angle-resolved photoemission (ARPES) in order to verify the existence of a recently proposed surface charge density wave (CDW) [Ch. R. Ast and H. Hoechst Phys. Rev. Lett. 90, 016403 (2003)]. The STM and TEM results to not support a CDW scenario at low temperatures. Furthermore, the quasiparticle interference pattern observed in STM confirms the spin-orbit split character of the surface states which prevents the formation of a CDW, even in the case of good nesting. The dispersion of the electronic states observed with ARPES agrees well with earlier findings. In particular, the Fermi contour of the electron pocket at the centre of the surface Brillouin zone is found to have a hexagonal shape. However, no gap opening or other signatures of a CDW phase transition can be found in the temperature-dependent data.

Superconductivity above 20 K in the Ba-K-Bi-O system  

Science Journals Connector (OSTI)

The results of magnetic susceptibility measurements on multiphase Ba-K-Bi-O samples with overall composition Ba0.9KxBiO3 (x?0.2) provide evidence for superconductivity above 20 K in a minority fraction (?5%) of the sample volume. These results support the expectation that K doping at the inactive Ba donor sites can extend the metallic range of the previously studied BaPb1-xBixO3 alloys closer to the BaBiO3 Peierls instability where the strong coupling of the conduction electrons to the O phonons could explain the enhanced (Tc?22 vs 13 K) superconducting transition temperatures.

Development of Wind-and-React Bi-2212 Accelerator MagnetTechnology  

SciTech Connect (OSTI)

We report on the progress in our R&D program, targetedto develop the technology for the application of Bi2Sr2CaCu2Ox (Bi-2212)in accelerator magnets. The program uses subscale coils, wound frominsulated cables, to study suitable materials, heat treatmenthomogeneity, stability, and effects ofmagnetic field and thermal andelectro-magnetic loads. We have addressed material and reaction relatedissues and report onthe fabrication, heat treatment, and analysis ofsubscale Bi-2212 coils. Such coils can carry a current on the order of5000 A and generate, in various support structures, magnetic fields from2.6 to 9.9 T. Successful coils are therefore targeted towards a hybridNb3Sn-HTS magnet which will demonstrate the feasibility of Bi-2212 foraccelerator magnets, and open a new magnetic field realm, beyond what isachievable with Nb3Sn.

Pairing and phase separation in BiO3-based superconductors  

Science Journals Connector (OSTI)

We study a model proposed before to give rise to a nonconventional pairing mechanism in BaPb1-xBixO3 and Ba1-xKxBiO3. This model, in which both phonons and electronic excitations play an essential role, is supported by experimental evidence. We solve exactly a BiO6 cluster and we calculate the interaction between this cluster and the rest of the system using perturbation theory in the hopping term. The holes introduced by doping form groups of n holes where n depends essentially on the values of the electron-phonon interaction, Bi-O repulsion, and Bi-O hopping. n=2 is favored near the limit at which the disproportionated ground state becomes unstable.

The electronic structure and photoluminescence properties of BiOCl:Eu3+ from first-principles calculations  

Science Journals Connector (OSTI)

Abstract Europium-doped luminescent heavy metal bismuth oxychloride has been investigated by first-principles calculation, and the crystal structure, electronic structure, and optical properties of pure BiOCl and Eu-doped BiOCl have been examined and compared. Based on the calculated results, the luminescence properties and mechanism of Eu-doped BiOCl has been discussed. Owing to the unique layered structure, BiOCl host could produce enough separated electron–hole pairs, under UV-light excitation. Furthermore, because the energy levels (5D0) of Eu3+ is matched with the energy bands (the bottom of conduction band) of BiOCl, the energy transport and charge transfer from host to luminescence center can be efficiently carried out. Thus, the photoluminescence of Eu3+ could be enhanced in the matrix of BiOCl. These findings are helpful to understand previously published experimental results, and to improve novel luminescence materials.

Lattice vibrations of pure and doped GaSe  

SciTech Connect (OSTI)

The Bridgman method is used to grow especially undoped and doped single crystals of GaSe. Composition and impurity content of the grown crystals were determined using X-ray fluorescence (XRF) method. X-ray diffraction, Raman scattering, photoluminescence (PL), and IR transmission measurements were performed at room temperature. The long wavelength lattice vibrations of four modifications of GaSe were described in the framework of modified one-layer linear-chain model which also takes into consideration the interaction of the selenium (Se) atom with the second nearest neighbor gallium (Ga) atom in the same layer. The existence of an eight-layer modification of GaSe is suggested and the vibrational frequencies of this modification are explained in the framework of a lattice dynamical model considered in the present work. Frequencies and the type of vibrations (gap, local, or resonance) for the impurity atoms were calculated and compared with the experimental results.

Mixed-metal bismuth-titanium species. Chemical routes to Bi{sub 4}Ti{sub 3}O{sub 12}  

SciTech Connect (OSTI)

Several routes to mixed-metal Bi-Ti species have been investigated. The inertness of bismuth alkoxides Bi(OR){sub 3} (R = Et, iPr) toward their titanium analogs could be overcome by controlled microhydrolysis of Bi alkoxides. The first mixed-metal species based on bismuth, BiTi{sub 2}O(OiPr){sub 9}, has thus been isolated and structurally characterized. Coatings of Bi{sub 4}Ti{sub 3}O{sub 12} have been deposited on silicon wafers by using the gels derived from Ti and Bi 2-methoxyethoxides solutions.

Nanoscale order in ZnSe:(Mg, O)  

SciTech Connect (OSTI)

Self-assembling of 1O4Mg identical tetrahedral clusters resulting in the nanoscale order in ZnSe:(Mg, O) is presented. Co-doping transforms ZnSe into Mg{sub x}Zn{sub 1?x}O{sub y}Se{sub 1?y} alloy of MgO, MgSe, ZnO and ZnSe. The decrease of a sum of the enthalpies of the constituent compounds and diminution of the strain energy are the causes of this phenomenon. The self-assembling conditions are obtained from the free energy minimum when magnesium and oxygen are in the dilute and ultra dilute limits, correspondingly. The occurrence of 1O4Mg clusters and completion of self-assembling when all oxygen atoms are in clusters are results of the continuous phase transitions. The self-assembling occurrence temperature does not depend on the oxygen content and it is a function of magnesium concentration. Mg{sub x}Zn{sub 1?x}O{sub y}Se{sub 1?y} with all oxygen atoms in clusters can be obtained in temperature ranges from T = 206 °C (x = 0.001, y = 1×10{sup ?4}) to T = 456 °C (x = 0.01, y = 1×10{sup ?4}) and from T = 237 °C (x = 0.001, y = 1×10{sup ?6}) to T = 462 °C (x = 0.01, y = 1×10{sup ?6})

Magneto-optical studies of ensembles of semimagnetic self-organized Cd(Mn)Se/Zn(Mn)Se Quantum Dots  

SciTech Connect (OSTI)

Ensembles of Cd(Mn)Se/ZnSe and CdSe/Zn(Mn)Se semimagnetic self-organized quantum dots with different Mn content have been studied by photoluminescence and resonant Raman scattering under strong magnetic fields in Faraday and Voigt geometries and with spectral and polarization selective excitation. Electron spin-flip Raman scattering has been observed in Voigt geometry in the structures with large Mn content. Narrow exciton peaks completely ?{sup ?}?{sup +} polarized have been observed under selective excitation in Faraday geometry in the structures with medium and small Mn content. A number of specific effects manifested themselves in the structures with a smallest Mn content where no Zeeman shift of the photoluminescence bands was observed.

Surface structure of liquid Bi and Sn: An x-ray reflectivity study  

SciTech Connect (OSTI)

X-ray reflectivity measurements of the liquid Bi surface are presented and analyzed together with previous liquid Sn results. Published measurements on liquid Ga, In, and K all exhibit a single strong maximum at a wave-vector transfer of the order of the reciprocal of an atomic-diameter, due to surface-induced layering. In contrast, both Sn and Bi exhibit - in addition - a weak broad peak at much smaller wave-vector transfers. This feature is an unambiguous signature of an enhanced electron density in the near-surface region. Possible ways of modeling this enhancement are presented. Once the different surface-roughening effects of thermal capillary waves are accounted for, the surface structure factors of Sn and Bi are remarkably similar. The principal difference between the two is that the depth of the layering below the surface is more than {approx}40% larger for Bi than for Sn. This is considerably larger than the ratio of their covalent radii which is only {approx}10%. No theoretical explanation can be offered at this time for the surface structure difference between Sn and Bi and other elemental liquid metals studied to date: Ga, In, and K.

Human papillomavirus 16 E5 induces bi-nucleated cell formation by cell-cell fusion  

SciTech Connect (OSTI)

Human papillomaviruses (HPV) 16 is a DNA virus encoding three oncogenes - E5, E6, and E7. The E6 and E7 proteins have well-established roles as inhibitors of tumor suppression, but the contribution of E5 to malignant transformation is controversial. Using spontaneously immortalized human keratinocytes (HaCaT cells), we demonstrate that expression of HPV16 E5 is necessary and sufficient for the formation of bi-nucleated cells, a common characteristic of precancerous cervical lesions. Expression of E5 from non-carcinogenic HPV6b does not produce bi-nucleate cells. Video microscopy and biochemical analyses reveal that bi-nucleates arise through cell-cell fusion. Although most E5-induced bi-nucleates fail to propagate, co-expression of HPV16 E6/E7 enhances the proliferation of these cells. Expression of HPV16 E6/E7 also increases bi-nucleated cell colony formation. These findings identify a new role for HPV16 E5 and support a model in which complementary roles of the HPV16 oncogenes lead to the induction of carcinogenesis.

Laser Ranging Delay in the Bi-Metric Theory of Gravity  

E-Print Network [OSTI]

We introduce a linearized bi-metric theory of gravity with two metrics. The metric g_{ab} describes null hypersurfaces of the gravitational field while light moves on null hypersurfaces of the optical metric \\bar{g}_{ab}. Bi-metrism naturally arises in vector-tensor theories with matter being non-minimally coupled to gravity via long-range vector field. We derive explicit Lorentz-invariant solution for a light ray propagating in space-time of the bi-metric theory and disentangle relativistic effects associated with the two metrics. This anlysis can be valuable for future spaceborne laser missions ASTROD and LATOR dedicated to map various relativistic gravity parameters in the solar system to unparalleled degree of accuracy.

BI-LAYER p-n JUNCTION INTERCONNECTIONS FOR COAL BASED SOLID OXIDE FUEL CELLS  

SciTech Connect (OSTI)

In this report, a new approach for lower operating temperature solid oxide fuel cells (SOFCs) interconnections (IC) consisting of a bi-layer structure is proposed and analyzed. The bi-layer structure consists of a p-type layer exposed to cathodic gas (air/oxygen) and an n-type layer exposed to anodic gas (fuel). It is theoretically shown that the interfacial oxygen partial pressure which is an important design variable, is dependent primarily on the oxygen partial pressure gradient across the IC, the low level oxygen conductivities of the two layers and is largely independent of their electronic conductivities and the total current density through the IC material. Experimental difficulties in fabricating bi-layer structures are presently being addressed.

Pairing mechanism in Bi-O superconductors: A finite-size chain calculation  

Science Journals Connector (OSTI)

We have studied the pairing mechanism in BiO3 systems by calculating the binding energy of a pair of holes in finite Bi-O chains, for parameters that simulate three-dimensional behavior. In agreement with previous results using perturbation theory in the hopping t, for covalent Bi-O binding and parameters for which the parent compound has a disproportionate ground state, pairing induced by the presence of biexcitons is obtained for sufficiently large interatomic Coulomb repulsion. The analysis of appropriate correlation functions shows a rapid metallization of the system as t and the number of holes increase. This fact shrinks the region of parameters for which the finite-size calculations can be trusted without further study. The same model for other parameters yields pairing in two other regimes: bipolaronic and magnetic excitonic.

Shubnikov-de Haas Oscillations in the Bulk Rashba Semiconductor BiTeI  

SciTech Connect (OSTI)

Bulk magnetoresistance quantum oscillations are observed in high quality single crystal samples of BiTeI. This compound shows an extremely large internal spin-orbit coupling, associated with the polarity of the alternating Bi, Te, and I layers perpendicular to the c-axis. The corresponding areas of the inner and outer Fermi surfaces around the A-point show good agreement with theoretical calculations, demonstrating that the intrinsic bulk Rashba-type splitting is nearly 360 meV, comparable to the largest spin-orbit coupling generated in heterostructures and at surfaces.

SciTech Connect (OSTI)

In this work, the latest results of developing high current ion beams of Au and Bi at GSI facility are described. The difficulties in the production of required charge state in vacuum arc discharge ion sources using the pure materials in the cathodes are discussed. As a possible solution, admix of a small amount of more refractory metal to the cathode material is considered. As a significant result, a dramatic improvement in the production of high charge state Bi ions using the mixed Bi-Cu cathodes (with 8%-15% of Cu admixed) compared to pure Bi cathodes is presented. The preliminary results of investigation of the material structure of Bi-Cu cathodes are discussed. As a next step, it is planned to test the composition of Au with Pd, Zr, and Fe as cathode materials.

The characteristic morphology of Bi{sub 2}O{sub 3} coating indicated that the electrode is stable during degradation. The Bi{sub 2}O{sub 3}/Ti electrode was used in oxidative degradation of Acid Orange 7 by electrolysis, photocatalytic oxidation and photoelectrocatalytic oxidation processes. The pseudo-first order kinetics parameter (K{sub app}) of photoelectrocatalytic process was 1.15 times of the sum of electrolysis and photocatalytic oxidation under visible light irradiation at 420 nm. The results indicated that the synergy of electrolysis and photocatalysis lead to an excellent photoelectrocatalytic property of the Bi{sub 2}O{sub 3}/Ti electrode.

WInd-and-react Bi-2212 coil development for accelerator magnets  

SciTech Connect (OSTI)

Sub-scale coils are being manufactured and tested at Lawrence Berkeley National Laboratory in order to develop wind-and-react Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} (Bi-2212) magnet technology for future graded accelerator magnet use. Previous Bi-2212 coils showed significant leakage of the conductors core constituents to the environment, which can occur during the partial melt reaction around 890 C in pure oxygen. The main origin of the observed leakage is intrinsic leakage of the wires, and the issue is therefore being addressed at the wire manufacturing level. We report on further compatibility studies, and the performance of new sub-scale coils that were manufactured using improved conductors. These coils exhibit significantly reduced leakage, and carry currents that are about 70% of the witness wire critical current (I{sub c}). The coils demonstrate, for the first time, the feasibility of round wire Bi-2212 conductors for accelerator magnet technology use. Successful high temperature superconductor coil technology will enable the manufacture of graded accelerator magnets that can surpass the, already closely approached, intrinsic magnetic field limitations of Nb-based superconducting magnets.

We report on the progress in our R&D program, targeted to develop the technology for the application of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} (Bi-2212) in accelerator magnets. The program uses subscale coils, wound from insulated cables, to study suitable materials, heat treatment homogeneity, stability, and effects of magnetic field and thermal and electro-magnetic loads. We have addressed material and reaction related issues and report on the fabrication, heat treatment, and analysis of subscale Bi-2212 coils. Such coils can carry a current on the order of 5000 A and generate, in various support structures, magnetic fields from 2.6 to 9.9 T. Successful coils are therefore targeted towards a hybrid Nb{sub 3}Sn-HTS magnet which will demonstrate the feasibility of Bi-2212 for accelerator magnets, and open a new magnetic field realm, beyond what is achievable with Nb{sub 3}Sn.

Local resistive switching behavior was investigated. Bipolar resistive switching characteristics were clearly observed in both two samples. However, for the Bi{sub 0.9}Sr{sub 0.1}FeO{sub 3} film, the switching from the low resistance (LRS) to the high resistance (HRS) occurred at positive bias and the switching from the HRS to the LRS at negative bias. On the contrary, the resistance of Bi{sub 0.9}Ca{sub 0.1}Fe{sub 0.9}Co{sub 0.1}O{sub 3} film was switched from the LRS to the HRS when a negative bias was applied. Possible mechanisms for both resistive switching forms were discussed on the basis of the Schottky-like barrier.

We report on our progress in the development of the technology for the application of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x}(Bi-2212) in Wind-and-React accelerator magnets. A series of superconducting subscale coils has been manufactured at LBNL and reacted at the wire manufacturer SWCC. Selected coils are impregnated and tested in self-field, even though the coils exhibited leakage during the partial melt heat treatment. Other coils have been disassembled after reaction and submitted to critical current (Ic) tests on individual cable sections. We report on the results of the current carrying capacity of the coils. Voltage-current (VI) transitions were reproducibly measured up to a quench currents around 1400 A, which is 25% of the expected performance. The results indicate that the coils are limited by the inner windings. We further compare possibilities to use Bi-2212 and Nb{sub 3}Sn tilted solenoid, and YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) racetrack inserts to increase the magnetic field in HD2, a 36 mm bore Nb{sub 3}Sn dipole magnet which recently achieved a bore magnetic field of 13.8 T. The application of Bi-2212 and/or YBCO in accelerator type magnets, if successful, will open the road to higher magnetic fields, far surpassing the limitations of Nb{sub 3}Sn magnet technology.

Photodetecting Properties of CuInSe2 Homojunctions  

Science Journals Connector (OSTI)

We studied the photovoltaic properties of homojunctions prepared by indium diffusion on p-type CuInSe2 at liquid nitrogen and room temperatures. The CuInSe2 was grown by the Bridgman method. We obtained the photovolatic spectra for both parallel and perpendicular incident lights with respect to the plane of the junciton (both on the p and n sides). The wavelength range was between 1.4 µm and 0.8 µm. We calculated a quantum efficiency of 40% at room temperature. This efficiency remained approximately constant between 1.2 µm and 0.9 µm. We have also measured response times for the junction at 300K. For change of incident light the response time is 1.2?10-6 sec and for change of bias the response time is 4?10-7 sec.

Metal contacts on ZnSe and GaN  

SciTech Connect (OSTI)

Recently, considerable interest has been focused on the development of blue light emitting materials and devices. The focus has been on GaN and ZnSe, direct band gap semiconductors with bands gaps of 3.4 and 2.6 eV, respectively. To have efficient, reliable devices it is necessary to have thermally and electrically stable Ohmic contacts. This requires knowledge of the metal-semiconductor reaction behavior. To date few studies have investigated this behavior. Much information has accumulated over the years on the behavior of metals on Si and GaAs. This thesis provides new knowledge for the more ionic wide band gap semiconductors. The initial reaction temperatures, first phases formed, and phase stability of Pt, Pd, and Ni on both semiconductors were investigated. The reactions of these metals on ZnSe and GaN are discussed in detail and correlated with predicted behavior. In addition, comparisons are made between these highly ionic semiconductors and Si and GaAs. The trends observed here should also be applicable to other II-VI and III-Nitride semiconductor systems, while the information on phase formation and stability should be useful in the development of contacts for ZnSe and GaN devices.

Insulation and Heat Treatment of Bi-2212 Wire for Wind-and-React Coils  

SciTech Connect (OSTI)

Higher Field Magnets demand higher field materials such as Bi-2212 round superconducting wire. The Bi-2212 wire manufacture process depends on the coil fabrication method and wire insulation material. Considering the wind-and-react method, the coil must unifirmly heated to the melt temperature and uniformly cooled to the solidification temperature. During heat treat cycle for tightly wound coils, the leakage melt from conductor can chemically react with insulation on the conductor and creat short turns in the coils. In this research project, conductor, insulation, and coils are made to systemically study the suitable insulation materials, coil fabrication method, and heat treatment cycles. In this phase I study, 800 meters Bi-2212 wire with 3 different insulation materials have been produced. Best insulation material has been identified after testing six small coils for insulation integrity and critical current at 4.2 K. Four larger coils (2" dia) have been also made with Bi-2212 wrapped with best insulation and with different heattreatment cycle. These coils were tested for Ic in a 6T background field and at 4.2 K. The test result shows that Ic from 4 coils are very close to short samples (1 meter) result. It demonstrates that HTS coils can be made with Bi-2212 wire with best insulation consistently. Better wire insulation, improving coil winding technique, and wire manufacture process can be used for a wide range of high field magnet application including acclerators such as Muon Collider, fusion energy research, NMR spectroscopy, MRI, and other industrial magnets.

Determination of Mass Attenuation Coefficients for CuInSe2 and CuGaSe2 Semiconductors  

SciTech Connect (OSTI)

This work presents mass attenuation coefficients values of CuInSe2 and CuGaSe2 semiconductor thin films commonly used in photovoltaic devices. The mass attenuation coefficients were measured at different energies from 11.9 to 37.3 keV by using the secondary excitation method. Monochromatic photons were obtained using the Br, Sr, Mo, Cd, Te, Ba and Nd secondary targets. 59.5 keV gamma rays emitted from an annular Am-241 radioactive source were used to excite secondary targets. Characteristic X-rays emitted from secondary target were counted by a Si(Li) detector with a resolution of 0.16 keV at 5.9 keV. The measured values were compared with theoretical values calculated using WinXCOM program.

Temperature-dependent structural property and power factor of n type thermoelectric Bi{sub 0.90}Sb{sub 0.10} and Bi{sub 0.86}Sb{sub 0.14} alloys  

SciTech Connect (OSTI)

Thermal variation of structural property, linear thermal expansion coefficient (?), resistivity (?), thermopower (S), and power factor (PF) of polycrystalline Bi{sub 1-x}Sb{sub x} (x?=?0.10 and 0.14) samples are reported. Temperature-dependent powder diffraction experiments indicate that samples do not undergo any structural phase transition. Rietveld refinement technique has been used to perform detailed structural analysis. Temperature dependence of ? is found to be stronger for Bi{sub 0.90}Sb{sub 0.10}. Also, PF for direct band gap Bi{sub 0.90}Sb{sub 0.10} is higher as compared to that for indirect band gap Bi{sub 0.86}Sb{sub 0.14}. Role of electron-electron and electron-phonon scattering on ?, S, and PF has been discussed.

Structure and phase transition of BiFeO{sub 3} cubic micro-particles prepared by hydrothermal method  

SciTech Connect (OSTI)

Graphical abstract: Bismuth ferrite (BiFeO{sub 3}) cubic micro-particles with smooth surfaces were synthesized. BiFeO{sub 3} has a hexagonal perovskite structure with a space group R3c below 370 °C and rhombohedral perovskite structure with a space group R3m below 755 °C, undergoes a phase transition in the temperature range of 755–817 °C to a cubic structure, then decompose to liquid and Fe{sub 2}O{sub 3} above 939 °C. Highlights: ? BiFeO{sub 3} micro-particles with smooth surface were synthesized by hydrothermal method. ? BiFeO{sub 3} enjoys hexagonal structure with well element ratio and chemical valence. ? BiFeO{sub 3} transition from rhombohedral phase to cubic phase lasts 60 °C. -- Abstract: Single-phase bismuth ferrite (BiFeO{sub 3}) powders were synthesized with a hydrothermal method by controlling the experimental conditions carefully. The powder structure, morphology and composition were characterized by using X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscope, Raman measurement and X-ray photoelectron spectroscopy. The particles change from irregular agglomerations to regular cubes with increasing KOH concentration. The large BiFeO{sub 3} cubic particles enjoy much smooth surfaces with well-matched element ratio (Bi:Fe:O = 1:1:3) and chemical valence (Bi{sup 3+}, Fe{sup 3+} and O{sup 2?}). The high temperature XRD and differential scanning calorimetry show that BiFeO{sub 3} powders have a hexagonal perovskite structure with a space group R3c below 370 °C and a rhombohedral structure with a space group R3m below 755 °C. BiFeO{sub 3} undergoes a phase transition in the temperature range of 755–817 °C from rhombohedral structure to a cubic phase, then decomposes to liquid and Fe{sub 2}O{sub 3} above 939 °C.

Development of Ag-clad Bi-2223 superconductors for electric power applications.  

SciTech Connect (OSTI)

Development of high-temperature superconductor technology will make possible the design and fabrication of smaller, lighter, and more efficient power devices such as motors, generators, transformers, transmission cables, and fault-current limiters. A prototype fault-current limiter, a 200-hp motor, and a 50-m-long transmission cable have already been demonstrated using Ag-clad Bi-2223 superconductor tapes. We have recently enhanced the transport current properties of long lengths of multifilament Ag-clad Bi-2223 tapes through increased packing density of precursor powder, improved mechanical deformation, optimization of conductor design, and adjusted cooling rate. These improved processing parameters had a pronounced effect on the transport critical current of the super-conducting tapes. Our improvements are briefly discussed and their implications are assessed in this paper.

Transition metal modified polycrystalline BiFeO3 (BFO) thin films have been deposited on Pt/TiO2/SiO2/Si substrate successfully through pulsed laser deposition (PLD). PV response is observed under illumination both in sandwich and lateral electrode configurations. The open-circuit voltage (Voc) and the short-circuit current density (Jsc) of the films in sandwich electrode configuration under illumination are measured to be 0.9 V and ?0.051 µA cm?2. Additionally, we report piezoresponse for BSFCO films, which confirms ferroelectric piezoelectric behaviour.

E-Print Network [OSTI]

The X-ray cascade from antiprotonic atoms was studied for 208Pb and 209Bi. Widths and shifts of the levels due to the strong interaction were determined. Using modern antiproton-nucleus optical potentials the neutron densities in the nuclear periphery were deduced. Assuming two parameter Fermi distributions (2pF) describing the proton and neutron densities the neutron rms radii were deduced for both nuclei. The difference of neutron and proton rms radii /\\r_np equal to 0.16 +-(0.02)_{stat} +- (0.04)_{syst} fm for 208Pb and 0.14 +- (0.04)_{stat} +- (0.04)_{syst} fm for 209Bi were determined and the assigned systematic errors are discussed. The /\\r_np values and the deduced shapes of the neutron distributions are compared with mean field model calculations.

Fragile antiferromagnetism in the heavy-fermion compound YbBiPt  

SciTech Connect (OSTI)

We report results from neutron scattering experiments on single crystals of YbBiPt that demonstrate antiferromagnetic order characterized by a propagation vector, ?AFM = (121212), and ordered moments that align along the [1 1 1] direction of the cubic unit cell. We describe the scattering in terms of a two-Gaussian peak fit, which consists of a narrower component that appears below TN?0.4 K and corresponds to a magnetic correlation length of ?n? 80 Å, and a broad component that persists up to T?? 0.7 K and corresponds to antiferromagnetic correlations extending over ?b? 20 Å. Our results illustrate the fragile magnetic order present in YbBiPt and provide a path forward for microscopic investigations of the ground states and fluctuations associated with the purported quantum critical point in this heavy-fermion compound.

BiMAT: a MATLAB(R) package to facilitate the analysis and visualization of bipartite networks  

E-Print Network [OSTI]

The statistical analysis of the structure of bipartite ecological networks has increased in importance in recent years. Yet, both algorithms and software packages for the analysis of network structure focus on properties of unipartite networks. In response, we describe BiMAT, an object-oriented MATLAB package for the study of the structure of bipartite ecological networks. BiMAT can analyze the structure of networks, including features such as modularity and nestedness, using a selection of widely-adopted algorithms. BiMAT also includes a variety of null models for evaluating the statistical significance of network properties. BiMAT is capable of performing multi-scale analysis of structure - a potential (and under-examined) feature of many biological networks. Finally, BiMAT relies on the graphics capabilities of MATLAB to enable the visualization of the statistical structure of bipartite networks in either matrix or graph layout representations. BiMAT is available as an open-source package at http://ecotheo...

Science Journals Connector (OSTI)

A consistent analysis of E2 transition probabilities for nine neutron-deficient even-even Se, Kr, and Sr isotopes has been performed, based on previous parametrizations for these nuclei within the proton-neutron interacting-boson model, from which boson effective charges e? and e? are deduced. Two sets of effective charges are obtained, one set having e??e? for most of the nuclei studied, and the other set having e? substantially larger than e? for most of the nuclei. For both sets, e? tends to decrease with increasing neutron number, while e? is roughly constant. More information on mixed-symmetry states is needed to determine which set is valid.

Fluorescence quenching of CdSe quantum dots on graphene  

SciTech Connect (OSTI)

We studied systematically the fluorescence quenching of CdSe quantum dots (QDs) on graphene and its multilayers, as well as graphene oxide (GO) and reduced graphene oxide (rGO). Raman intensity of QDs was used as a quantitatively measurement of its concentration in order to achieve a reliable quenching factor (QF). It was found that the QF of graphene (?13.1) and its multilayers is much larger than rGO (?4.4), while GO (?1.5) has the lowest quenching efficiency, which suggests that the graphitic structure is an important factor for quenching the fluorescence of QDs. It was also revealed that the QF of graphene is not strongly dependent on its thicknesses.

Geometric Tracking Control of a Quadrotor UAV on SE(3)  

E-Print Network [OSTI]

This paper provides new results for the tracking control of a quadrotor unmanned aerial vehicle (UAV). The UAV has four input degrees of freedom, namely the magnitudes of the four rotor thrusts, that are used to control the six translational and rotational degrees of freedom, and to achieve asymptotic tracking of four outputs, namely, three position variables for the vehicle center of mass and the direction of one vehicle body-fixed axis. A globally defined model of the quadrotor UAV rigid body dynamics is introduced as a basis for the analysis. A nonlinear tracking controller is developed on the special Euclidean group SE(3) and it is shown to have desirable closed loop properties that are almost global. Several numerical examples, including an example in which the quadrotor recovers from being initially upside down, illustrate the versatility of the controller.

Carrier cooling and exciton formation in GaSe  

Science Journals Connector (OSTI)

The initial cooling of hot carriers and the subsequent exciton formation in GaSe are studied by time-resolved photoluminescence (PL) using femtosecond up-conversion techniques. From the time-resolved PL spectra of this layered III-VI semiconductor two different energy relaxation channels are derived. After an initial subpicosecond cooling due to Fröhlich-type interaction of carriers with longitudinal optical E?(22) phonons a slower regime follows, which is dominated by deformation potential interaction with the nonpolar optical A1?(12) phonons. The coupling constant for nonpolar optical phonon scattering is derived. The subsequent formation of excitons is studied at different carrier densities and detection energies. A cross section for the free-exciton formation is determined based on a rate equation model.

Quasi-linear heating and acceleration in bi-Maxwellian plasmas  

SciTech Connect (OSTI)

Quasi-linear acceleration and heating rates are derived for drifting bi-Maxwellian distribution functions in a general nonrelativistic case for arbitrary wave vectors, propagation angles, and growth/damping rates. The heating rates in a proton-electron plasma due to ion-cyclotron/kinetic Alfvén and mirror waves for a wide range of wavelengths, directions of propagation, and growth or damping rates are explicitly computed.

Conductivity anisotropy in the doped Bi{sub 2}Te{sub 3} single crystals  

SciTech Connect (OSTI)

Temperature dependences (temperature range T = 0.5-300 K) of resistivity in the plane of layers and in the direction perpendicular to the layers, and the galvanomagnetic effects in undoped and doped Bi{sub 2}Te{sub 3} single crystals are studied (magnetic field H < 80 kOe, T = 0.5-4.2 K). It is shown that upon doping of Bi{sub 2}Te{sub 3} with the Group III atoms (In and B), conductivity anisotropy increases mainly due to an increase in resistivity in the direction perpendicular to the layers. This fact makes it possible to assume that the atoms of these impurities are incorporated mainly into the van der Waal gaps between the layers upon doping. It is also revealed that, upon doping of Bi{sub 2}Te{sub 3} with In and B, the temperature dependence of conductivity becomes weaker, which indicates an increase in the role of scattering by defects in scattering mechanisms. The concentrations and mobilities of charge carriers, values of the Hall factor conditioned by the anisotropy of effective masses and orientation of ellipsoids with respect to crystallographic axes, areas of the extreme section of the Fermi surface by the plane perpendicular to the direction of the magnetic field, and the Fermi energy are evaluated.

Photovoltaic mechanism in Na-substituted BiFeO3 films  

Science Journals Connector (OSTI)

Na-substituted BiFeO3 films were prepared on FTO/glass substrates using the sol–gel method. XRD results showed that all films adopted random orientation and an R3m perovskite structure. UV–Vis absorption results indicated that the films exhibited intense absorbance around 450 nm. The band gaps were 2.59 eV, 2.63 eV, 2.62 eV and 2.52 eV for the films substituted with 0%, 5%, 10% and 20% Na, respectively. A substantially enhanced photovoltaic effect was observed in the 20% Na substituted BiFeO3 film; its short-circuit current density was 1.26 µA cm?2 and the open circuit voltage was ?0.66 V. Meanwhile, polarization-modulated Jsc and Voc were observed in the 20% Na substituted BiFeO3 film and the mechanism was studied using the Schottky barrier combined with the ferroelectric polarization model.

Interplay between intrinsic and stacking-fault magnetic domains in bi-layered manganites  

SciTech Connect (OSTI)

We present a low temperature X-ray photoemission electron microscopy study of the bi-layered manganite compound La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} (BL-LSMO) to investigate the influence of stacking faults, which are structurally and magnetically different from the bi-layered host. In BL-LSMO small magnetic moment persists to T* = 300K, well above the Curie temperature of 120K (T{sub C}). Our magnetic images show that 3D stacking faults are responsible for the T* transition. Furthermore, close to the T{sub C}, stacking faults are well coupled to the bi-layered host with latter magnetic domains controlling the spin direction of the stacking faults. Contrary to recent reports, we find that stacking faults do not seed magnetic domains in the host via an exchange spring mechanism and the intrinsic T{sub C} of the BL-LSMO is not lower than 120K.

Tunable atomic termination in nano-necklace BiFeO{sub 3}  

SciTech Connect (OSTI)

We investigate the growth kinetics of BiFeO{sub 3} (BFO) nano-necklace based on first principles modeling and electrospinning experiments. A two-step layered growth mechanism is proposed to control the atomic termination of each nano-necklace. X-ray diffraction (XRD) results agree well with our model predictions; (1) samples calcined at 500 and 550?°C consist of FeO{sub 2} (F-F) terminated nano-necklace, (2) samples calcined at 650?°C consist of either BiO (B-B) or BiO and FeO{sub 2} (B-F) terminated ones. The XRD diffraction peaks are located at lower 2? values with a magnetic moment of 3.0?emu/g for the former and at higher 2? values with a decrease in the magnetic moment to 0.4?emu/g for the later samples. The activation energy associated with the growth of the nano-necklaces was experimentally determined to be 0.37?eV/atom. This study provides fundamental understanding for the long-sought layer-by-layer assembly of BFO nanostructures.

Isomers in three doubly odd Fr-At-Bi ?-decay chains  

Science Journals Connector (OSTI)

The ?202206At?198Bi, ?200204At?196Bi, and ?198202At?194Bi a-decay chains have been studied by standard spectroscopic techniques using an on-line isotope separator. All the studied doubly odd isotopes have at least two isomers, which decay by a combination of the following decay modes: a emission, ?+/EC (electron capture) decay, and internal transition (IT). The internal transition, a highly retarded E3, is the j-forbidden transition between the [?h9/2??i13/2]10- and the [?h9/2??f5/2]7+ states. The B(E3) values of these IT’s together with their energy behavior as a function of the neutron and proton number, compared to the energy difference between the 13/2+(?i13/2) and 5/2-(?f5/2) states in the odd-mass Pb isotones, indicate that these proton-neutron-coupled states have a rather pure shell-model character.

We present a detailed study of RNi1?xBi2±y (R = La–Nd, Sm, Gd–Dy) single crystals by measurements of stoichiometry and temperature dependent magnetic susceptibility, magnetization, and electrical resistivity. This series forms with partial Ni occupancy, 0.72 ? (1?x) ? 0.84, as well as a variable Bi occupancy, 1.76 ? (2±y) ? 2.14. For R = Ce–Nd, Gd–Dy, the RNi1?xBi2±y compounds show local-moment like behavior and order antiferromagnetically at low temperatures. Determination of anisotropies as well as antiferromagnetic ordering temperatures for RNi1?xBi2±y (R = Ce–Nd, Sm, Gd–Dy) have been made. Crystalline samples from this family exhibit minority, second phase superconductivity at low temperatures, which can be associated with Ni–Bi and Bi contamination. No evidence of bulk superconductivity has been observed.

Photoluminescence study of the substitution of Cd by Zn during the growth by atomic layer epitaxy of alternate CdSe and ZnSe monolayers  

SciTech Connect (OSTI)

We present a study of the substitution of Cd atoms by Zn atoms during the growth of alternate ZnSe and CdSe compound monolayers (ML) by atomic layer epitaxy (ALE) as a function of substrate temperature. Samples contained two quantum wells (QWs), each one made of alternate CdSe and ZnSe monolayers with total thickness of 12 ML but different growth parameters. The QWs were studied by low temperature photoluminescence (PL) spectroscopy. We show that the Cd content of underlying CdSe layers is affected by the exposure of the quantum well film to the Zn flux during the growth of ZnSe monolayers. The amount of Cd of the quantum well film decreases with higher exposures to the Zn flux. A brief discussion about the difficulties to grow the Zn{sub 0.5}Cd{sub 0.5}Se ordered alloy (CuAu-I type) by ALE is presented.

Phase transitions, electrical conductivity and chemical stability of BiFeO{sub 3} at high temperatures  

SciTech Connect (OSTI)

The multiferroic perovskite BiFeO{sub 3} is reported to display two first order structural phase transitions. The structural phase transition at 925+-5 deg. C is demonstrated to be first order by calorimetry and dilatometry. Electrical conductivity measurements revealed that the high temperature phase above 925+-5 deg. C is semiconducting, in disagreement with recent reports. The sign and magnitude of the volumes of transition reflect the sign and magnitude of the discontinuities in electrical conductivity across the two first order phase transitions. A high partial pressure of oxygen was demonstrated to stabilise BiFeO{sub 3} towards peritectic decomposition. Finally, the origins of the commonly observed decomposition of BiFeO{sub 3} at high temperatures are discussed. - Graphical abstract: The structural phase transitions of multiferroic BiFeO{sub 3} are shown to first order, with discontinuous volume and electrical conductivity. Semiconductivity was found for all three polymorphs of BiFeO{sub 3}.

Theoretical investigation of charge accumulation layer on the Bi-induced InAs(111)-(2?×?2) surface  

SciTech Connect (OSTI)

Based on pseudopotential method and density functional theory, we have investigated the stability, atomic geometry, and detailed electronic structures for Bi adsorbates on the InAs(111)-(2?×?2) surface with three different sites: (i) T{sub 4} (Bi trimer centered on T{sub 4} site), (ii) H{sub 3} (Bi trimer centered on H{sub 3} site), and (iii) T{sub 4}–H{sub 3} (which is formed by trimers with opposite orientations: one centered on a T{sub 4} site and the other on a H{sub 3}). Our total energy calculations suggest that adsorption on the T{sub 4}–H{sub 3} site is the energetically most stable structure among the proposed structures. The electronic band structure calculations reveal the existence of an accumulation layer between InAs(111) surface and Bi adatoms for T{sub 4}–H{sub 3}. Charge density difference results indicate significant amount of the charge accumulation on the Bi/InAs interface.

Space charge limited current conduction in Bi{sub 2}Te{sub 3} thin films  

SciTech Connect (OSTI)

Bi{sub 2}Te{sub 3} is known for its large thermoelectric coefficients and is widely used as a material for Peltier devices. Bi{sub 2}Te{sub 3} thin films with thicknesses in the range 125-300 A have been prepared by Flash Evaporation at a pressure of 10{sup -5} m bar on clean glass substrates at room temperature. An Al-Bi{sub 2}Te{sub 3}-Al sandwich structure has been used for electrical conduction properties in the temperature range 303 to 483 K. I-V characteristics showed Ohmic conduction in the low voltage region. In the higher voltage region, a Space Charge Limited Conduction (SCLC) takes place due to the presence of the trapping level. The transition voltage (V{sub t}), between the Ohmic and the SCLC condition was proportional to the square of thickness. Further evidence for this conduction process was provided by the linear dependence of V {sub t} on t {sup 2} and log J on log t. The hole concentration in the films were found to be n {sub 0} = 1.65 * 10{sup 10} m{sup -3}. The carrier mobility increases with increasing temperature whereas the density of trapped charges decreases with increasing temperature. The barrier height decreases with an increase in temperature. The increase in the trapping concentration V {sub t} is correlated with ascending the degree of preferred orientation of the highest atomic density plane. The activation energy was estimated and the values found to decrease with increasing applied voltage. The zero field value of the activation energy is found to be 0.4 eV.

SciTech Connect (OSTI)

Lithium additions to the high-temperature superconductor Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} (2212) increased superconducting transition temperatures and improved resistance to effects of magnetic fields. In addition, these additions lowered the melting point of 2212 and increased reaction kinetics. Ag-clad tapes fabricated from 2212 with and without Li exhibited profound differences. For heating to temperatures less than or equal to 840{degrees}C, grain growth and sintering were much more substantial in the tapes containing Li.

Asymmetric profiles observed in the recombination of Bi79+: A benchmark for relativistic theories involving interference  

Science Journals Connector (OSTI)

Asymmetric profiles have been observed in the recombination cross section of Be-like Bi obtained by measuring the electron energy dependence of the ion abundance ratio in an electron-beam ion trap. In contrast to the previous x-ray measurements, the present measurement gives the integrated recombination cross section with higher statistical quality, which provides a benchmark to test the relativistic theory involving the interference between the resonant and continuum states. The comparison with our theoretical study shows that the Breit interaction plays an important role in this case.

SciTech Connect (OSTI)

Testing, results and analysis of a Bi-2223 model superconducting generator coil produced under the DOE Superconductivity Partnership Initiative are presented. The test arrangement enables coil energization with dc and transient currents over a range of operating temperatures to explore coil performance under conditions analogous to those that would be experienced by a superconducting generator field coil. Analytical calculations of coil ac and ohmic losses and temperature rise compare well with experimental measurements. Good performance is predicted for a typical 3-phase fault condition. Coil steady state and transient performance can be predicted with confidence for full scale superconductor application.

Collisional effect on the Weibel instability with the bi-Maxwellian distribution function  

SciTech Connect (OSTI)

In this paper, the Coulomb collision effect of electron-ion is investigated based on the equilibrium bi-Maxwellian anisotropic distribution function in dense and unmagnetized plasma. An analytical expression is derived for the real frequency and the growth rate of the Weibel instability for two limiting cases |?=(?{sup ?}/k{sub ||}?{sub ||})|?1 and |?|?1. In the limit |?|?1, the quantity ? that is due to a collisional term will appear in the growth and condition of the rate of the Weibel instability, which leads to a constraining condition of the growth rate. When ? increases, the growth rate will increase and the wave instability will be distant from its own damping mode.

Optical and Electrical Properties of Al/(p)Bi{sub 2}S{sub 3} Schottky Junction  

SciTech Connect (OSTI)

Thin film Al/(p)Bi{sub 2}S{sub 3} Schottky junctions were prepared by vacuum evaporation under pressure 10{sup -6} Torr. The p-type Bi{sub 2}S{sub 3} thin films with acceptor concentration (3.36-7.33)x10{sup 16}/cm{sup 3} were obtained by evaporating 'In' along with Bi{sub 2}S{sub 3} powder and then annealing the films at 453K for 5 hours. Different junction-parameters such as ideality factor, barrier height, effective Richardson's constant, short-circuit current, etc. were determined from I-V characteristics. The junctions exhibited rectifying I-V characteristics and also photovoltaic effect. Ideality factor was found to decrease with the increase of temperature. Proper doping, annealing, and hydrogenation are necessary to reduce the series resistance so as to achieve high carrier efficiency. More works are being carried out in this direction.

Crystal growth and electronic properties of a 3D Rashba material, BiTeI, with adjusted carrier concentrations  

Science Journals Connector (OSTI)

3D Rashba materials can be a leading player in spin-related novel phenomena, ranging from the metallic extreme (unconventional superconductivity) to the transport intermediate (spin Hall effects) to the novel insulating variant (3D topological insulating states). As the essential backbone for both fundamental and applied research of such a 3D Rashba material, this study established the growth of sizeable single crystals of a candidate compound BiTeI with adjusted carrier concentrations. Three techniques (standard vertical Bridgman, modified horizontal Bridgman, and vapour transport) were employed, and BiTeI crystals (>1 ? 1 ? 0.2 mm3) with fundamentally different electronic states from metallic to insulating were successfully grown by the chosen technique. The 3D Rashba electronic states, including the Fermi surface topology, for the corresponding carrier concentrations of the obtained BiTeI crystals were revealed by relativistic first-principles calculations.

BiFeO3 Domain Wall Energies and Structures: A Combined Experimental and Density Functional Theory+U Study  

DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

We determined the atomic structures and energies of 109°, 180°, and 71° domain walls in BiFeO3, combining density functional theory+U calculations and aberration-corrected transmission electron microscopy images. We find a substantial Bi sublattice shift and a rather uniform Fe sublattice across the walls. The calculated wall energies (?) follow the sequence ?109 180 71 for the 109°, 180°, and 71° walls. We attribute the high 71° wall energy to an opposite tilting rotation of the oxygen octahedra and the low 109° wall energy to the opposite twisting rotation of the oxygen octahedra across the domain walls.

Development of a low-cost bi-axial intensity-based optical fibre accelerometer for wind turbine blades  

Science Journals Connector (OSTI)

Abstract A bi-axial optical fibre accelerometer was developed for wind turbine monitoring. The sensor was fabricated from intensity-modulated optical fibre, which is low-cost, lightweight and simple in design. The bi-axial acceleration was measured by light intensity coupling between a cantilever fibre and two receiving fibres. Numerical simulation was performed to obtain the light coupling characteristics and the results were used to design the sensor parameters. A prototype was fabricated and the calibration scheme validated experimentally. The performance of the prototype was tested in terms of frequency response and linearity.

Pushing the Theoretical Limit of Li-CFx Batteries: A Tale of Bi-functional Electrolyte  

SciTech Connect (OSTI)

In a typical battery, electrodes deliver capacities less or equal the theoretical maxima of the electrode materials.1 The inert electrolyte functions solely as the ionic conductor without contribution to the cell capacity because of its distinct mono-function in the concept of conventional batteries. Here we demonstrate that the most energy-dense Li-CFx battery2 delivers a capacity exceeding the theoretical maximum of CFx with a solid electrolyte of Li3PS4 (LPS) that has dual functions: as the inert electrolyte at the anode and the active component at the cathode. Such a bi-functional electrolyte reconciles both inert and active characteristics through a synergistic discharge mechanism of CFx and LPS. Li3PS4 is known as an inactive solid electrolyte with a broad electrochemical window over 5 V.3 The synergy at the cathode is through LiF, the discharge product of CFx, which activates the electrochemical discharge of LPS at a close electrochemical potential of CFx. Therefore, the solid-state Li-CFx batteries output 126.6% energy beyond their theoretic limits without compromising the stability of the cell voltage. The extra energy comes from the electrochemical discharge of LPS, the inert electrolyte. This bi-functional electrolyte revolutionizes the concept of conventional batteries and opens a new avenue for the design of batteries with an unprecedentedly high energy density.

The Band Spectra of SbF and BiF  

Science Journals Connector (OSTI)

New band spectra attributed to the molecules SbF and BiF have been excited by active nitrogen. The spectrum of SbF from 2000-5500A is found to have three groups of bands lying in the regions 3600-5200A, 2600-2700A and 2200-2430A. Analysis of the first group shows that sixty-one bands out of sixty-nine can be placed into two systems with the following vibrational constants, in cm-1:— System?e?e?xe??e??e??xe???e??A121887.5411.31.71616.92.89A223992.5420.01.75612.62.58 The second group consists of a few isolated bands degraded to shorter wave-lengths and the third of bands in closely spaced sequences and also degraded to shorter wave-lengths. A preliminary analysis indicates that the bands in the latter group can be placed into two systems for which ?e??700 cm-1, ?e???620 cm-1 and ??21?1850 cm-1. Three new systems of bands, degraded to shorter wave-lengths and forming a triplet system with wide multiplet separations, (7330 cm-1 and 4800 cm-1), are found in the spectrum of BiF at 3050-3250A, 2650-2850A and 2250-2350A. Photographs taken with small dispersion indicate that ?e??620 cm-1 and ?e???520 cm-1.

Magnetic-field-tuned quantum criticality of the heavy-fermion system YbPtBi  

SciTech Connect (OSTI)

In this paper, we present systematic measurements of the temperature and magnetic field dependencies of the thermodynamic and transport properties of the Yb-based heavy fermion YbPtBi for temperatures down to 0.02 K with magnetic fields up to 140 kOe to address the possible existence of a field-tuned quantum critical point. Measurements of magnetic-field- and temperature-dependent resistivity, specific heat, thermal expansion, Hall effect, and thermoelectric power indicate that the AFM order can be suppressed by an applied magnetic field of Hc?4 kOe. In the H-T phase diagram of YbPtBi, three regimes of its low-temperature states emerge: (I) AFM state, characterized by a spin density wave-like feature, which can be suppressed to T=0 by the relatively small magnetic field of Hc?4 kOe; (II) field-induced anomalous state in which the electrical resistivity follows ??(T)?T1.5 between Hc and ?8 kOe; and (III) Fermi liquid (FL) state in which ??(T)?T2 for H?8 kOe. Regions I and II are separated at T=0 by what appears to be a quantum critical point. Whereas region III appears to be a FL associated with the hybridized 4f states of Yb, region II may be a manifestation of a spin liquid state.

Alloys in the TlSe-Se system on the side of the TlSe compound in the phase diagram have been investigated using differential thermal, X-ray powder diffraction, and microstructural analyses. The phase diagram of the system has been constructed, and the temperature dependences of the electrical conductivity of the phases obtained have been examined. An analysis of the thermograms of alloys in the (TlSe){sub 0.96}-Se{sub 0.04} system has revealed a structural phase transition at a temperature of 470 {+-} 1 K. Investigations into the temperature dependences of the electrical conductivity in the range 120-450 K have demonstrated that the temperature dependence of the electrical conductivity for the (TlSe){sub 0.96}-Se{sub 0.04} alloy exhibits metallic behavior.

Type Ia Supernovae with Bi-Modal Explosions Are Common -- Possible Smoking Gun for Direct Collisions of White-Dwarfs  

E-Print Network [OSTI]

We discover clear doubly-peaked line profiles in 3 out of ~20 type Ia supernovae (SNe Ia) with high-quality nebular-phase spectra. The profiles are consistently present in three well-separated Co/Fe emission features. The two peaks are respectively blue-shifted and red-shifted relative to the host galaxies and are separated by ~5000 km/s. The doubly-peaked profiles directly reflect a bi-modal velocity distribution of the radioactive Ni56 in the ejecta that powers the emission of these SNe. Due to their random orientations, only a fraction of SNe with intrinsically bi-modal velocity distributions will appear as doubly-peaked spectra. Therefore SNe with intrinsic bi-modality are likely common, especially among the SNe in the low-luminosity (~40% of all SNe Ia) part on the Philips relation \\Delta m15(B) >~ 1.3. Bi-modality is naturally expected from direct collisions of white dwarfs (WDs) due to the detonation of both WDs and is demonstrated in a 3D 0.64 M_Sun-0.64 M_Sun WD collision simulation.

Performance of Titanium-Oxide/Polymer Insulation in Bi-2212/Ag-alloy Round Wire Wound Superconducting Coils  

E-Print Network [OSTI]

Conductor insulation is one of the key components needed to make Ag-alloy clad Bi2Sr2CaCu2O8+x (Bi-2212/Ag) superconducting round wire (RW) successful for high field magnet applications as dielectric standoff and high winding current densities (Jw) directly depend on it. In this study, a TiO2/polymer insulation coating developed by nGimat LLC was applied to test samples and a high field test coil. The insulation was investigated by differential thermal analysis (DTA), thermo-gravimetric analysis (TGA), scanning electron microscopy (SEM), dielectric properties measurement, and transport critical current (Ic) properties measurement. About 29% of the insulation by weight is polymer. When the Bi-2212/Ag wire is full heat treated, this decomposes with slow heating to 400{\\deg}C in pure O2. After the full reaction, we found that the TiO2 did not degrade the critical current properties, adhered well to the conductor, and provided a breakdown voltage of >100 V, which allowed the test coil to survive quenching in 31.2 T background field, while providing a 2.6 T field increment. For Bi-2212/Ag RW with a typical diameter of 1.0-1.5 mm, this ~15 um thick insulation allows a very high coil packing factor of ~0.74, whereas earlier alumino-silicate braid insulation only allows packing factors of 0.38-0.48.

Graphical abstract: - Highlights: • ·OH trap and hole sink were involved to investigate the active radicals. • Holes play a more important role in the degradation of RhB. • The ·OH were related to the decomposition of phenol. • The ·O{sub 2}-played a leading role in the photodegradation of phenol. • Blue LED is competitive and promising alternative for the future application. - Abstract: Bi{sub 2}MoO{sub 6} has been reported as a promising photocatalyst in wastewater treatment. The active radicals generated over the Bi{sub 2}MoO{sub 6} during the photocatalytic process were thought to be hydroxyl radical (·OH) but have not been proved. Herein, Bi{sub 2}MoO{sub 6} with nanoplate like morphology was synthesized and its photocatalytic performances in the degradation of rhodamine B (RhB) and phenol as colored and colorless model pollutants respectively were evaluated under the irradiation of blue light emitting diode (LED). The tert-butyl alcohol (TBA) as a ·OH trap and ethylene diamine tetraacetic acid (EDTA) as a hole sink were involved to investigate the main active groups that are generated on Bi{sub 2}MoO{sub 6} and function during the photodegradation of RhB and phenol. In addition, it is a competitive and promising alternative plan to use blue LED as light source for the future practical application in environmental remediation.

Structural and electronic properties of Bi-adsorbate-stabilized reconstructions on the InP(100) and GaAsxN1?x(100) surfaces  

Science Journals Connector (OSTI)

Bismuth (Bi) adsorbate-stabilized reconstructions on the InP(100) and GaAsxN1?x(100) surfaces have been studied by scanning tunneling microscopy (STM) and spectroscopy (STS), x-ray photoelectron spectroscopy, and low-energy electron diffraction. With decreasing coverage, Bi is found to stabilize the (2×1), (2×8), and (2×4) reconstructions on the InP(100) surface and the (2×1) and (2×4) reconstructions on the GaAsxN1?x(100). STM results show that both the Bi?InP(100)(2×4) and Bi?GaAsxN1?x(100)(2×4) reconstructions can be described with the ?2-like structural model. The current-voltage curves measured by STS show the Bi?InP(100)(2×1) and Bi?GaAsxN1?x(100)(2×1) structures, which do not obey the electron counting model, to be semiconducting and metallic, respectively. Combining our experimental findings, we propose atomic models for the (2×1) reconstructions. An issue why Bi stabilizes unusual (2×1) structures is discussed.

Terahertz Spectroscopy of Spin Waves in Multiferroic BiFeO3 in High Magnetic Fields  

DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

We have studied the magnetic field dependence of far-infrared active magnetic modes in a single ferroelectric domain BiFeO3 crystal at low temperature. The modes soften close to the critical field of 18.8 T along the [001] (pseudocubic) axis, where the cycloidal structure changes to the homogeneous canted antiferromagnetic state and a new strong mode with linear field dependence appears that persists at least up to 31 T. A microscopic model that includes two Dzyaloshinskii-Moriya interactions and easy-axis anisotropy describes closely both the zero-field spectroscopic modes as well as their splitting and evolution in a magnetic field. The good agreement of theory with experiment suggests that the proposed model provides the foundation for future technological applications of this multiferroic material.

Thermal-mechanical Properties of Epoxy-impregnated Bi-2212/Ag Composite  

SciTech Connect (OSTI)

Knowledge of the thermal-mechanical properties of epoxy/superconductor/insulation composite is important for designing, fabricating, and operating epoxy impregnated high field superconducting magnets near their ultimate potentials. We report measurements of the modulus of elasticity, Poisson’s ratio, and the coefficient of thermal contraction of epoxy-impregnated composite made from the state-of-the-art powder-in-tube multifilamentary Ag/Bi2Sr2CaCu2Ox round wire at room temperature and cryogenic temperatures. Stress-strain curves of samples made from single-strand and Rutherford cables were tested under both monotonic and cyclic compressive loads, with single strands insulated using a thin TiO2 insulation coating and the Rutherford cable insulated with a braided ceramic sleeve.

Electric field control of magnetism using BiFeO{sub 3}-based heterostructures  

SciTech Connect (OSTI)

Conventional CMOS based logic and magnetic based data storage devices require the shuttling of electrons for data processing and storage. As these devices are scaled to increasingly smaller dimensions in the pursuit of speed and storage density, significant energy dissipation in the form of heat has become a center stage issue for the microelectronics industry. By taking advantage of the strong correlations between ferroic orders in multiferroics, specifically the coupling between ferroelectric and magnetic orders (magnetoelectricity), new device functionalities with ultra-low energy consumption can be envisioned. In this article, we review the advances and highlight challenges toward this goal with a particular focus on the room temperature magnetoelectric multiferroic, BiFeO{sub 3}, exchange coupled to a ferromagnet. We summarize our understanding of the nature of exchange coupling and the mechanisms of the voltage control of ferromagnetism observed in these heterostructures.

Magnetic structure and spin excitations in BaMn2Bi2  

SciTech Connect (OSTI)

We present a single crystal neutron scattering study of BaMn2Bi2, a recently synthesized material with the same ThCr2Si2-type structure found in several Fe-based unconventional superconducting materials. We show long range magnetic order, in the form of a G-type antiferromagnetic structure, to exist up to 390 K with an indication of a structural transition at 100 K. Utilizing inelastic neutron scattering we observe a spin-gap of 16 meV, with spin-waves extending up to 55 meV. We find these magnetic excitations are well fit to a J1-J2-Jc Heisenberg model and present values for the exchange interactions. The spin wave spectrum appears to be unchanged by the 100 K structural phase transition.

Disentangling reaction mechanisms for ? production in the 6Li + 209Bi reaction  

Science Journals Connector (OSTI)

Inclusive breakup ? cross sections (??incl) are measured for the 6Li?+?209Bi reaction at bombarding energies Elab=24–50 MeV. The ??incl was observed to be a substantial fraction of the total reaction cross section over the entire energy range, and it exhausts almost whole of the reaction cross section at sub-barrier energies. An investigation on the origin of large inclusive ? reveals that most of the ? particles are produced by noncapture breakup (6Li??+d) and incomplete fusion via d capture. The combined cross sections of noncapture breakup, d capture, and transfer reactions successfully explain the origin of most of the experimental ??incl over the measured energy range. A comparison of the ??incl versus reduced energies for several targets involving 6Li as projectile shows that the cross sections are independent of target. Interestingly, the difference between reaction and complete fusion cross sections “?reac??CF” for several reactions also shows the same behavior.

Pulsed laser deposition of Mn doped CdSe quantum dots for improved solar cell performance  

SciTech Connect (OSTI)

In this work, we demonstrate (1) a facile method to prepare Mn doped CdSe quantum dots (QDs) on Zn{sub 2}SnO{sub 4} photoanodes by pulsed laser deposition and (2) improved device performance of quantum dot sensitized solar cells of the Mn doped QDs (CdSe:Mn) compared to the undoped QDs (CdSe). The band diagram of photoanode Zn{sub 2}SnO{sub 4} and sensitizer CdSe:Mn QD is proposed based on the incident-photon-to-electron conversion efficiency (IPCE) data. Mn-modified band structure leads to absorption at longer wavelengths than the undoped CdSe QDs, which is due to the exchange splitting of the CdSe:Mn conduction band by the Mn dopant. Three-fold increase in the IPCE efficiency has also been observed for the Mn doped samples.

Direct Patterning of CdSe Quantum Dots into Sub-100 nm Structures  

SciTech Connect (OSTI)

Ordered, two-dimensional cadmium selenide (CdSe) arrays have been fabricated on indium-doped tin oxide (ITO) electrodes using the pattern replication in nonwetting templates (PRINT) process. CdSe quantum dots (QDs) with an average diameter of 2.7 nm and a pyridine surface ligand were used for patterning. The PRINT technique utilizes a perfluoropolyether (PFPE) elastomeric mold that is tolerant of most organic solvents, thus allowing solutions of CdSe QDs in 4-picoline to be used for patterning without significant deformation of the mold. Nanometer-scale diffraction gratings have been successfully replicated with CdSe QDs.

Optical and electrochemical properties of CuInSe2 and CuInS2?CuInSe2 alloys  

Science Journals Connector (OSTI)

The fundamental optical transitions in single crystals of CuInS2 x Se2 ? 2 x alloys have been studied by electrolyte electroreflectance (EER) spectroscopy. The band gap of the alloys increases nonlinearly with increasing sulphur content corresponding to a bowing parameter 0.14. The flatband potential derived from the EER spectra is in excellent agreement with differential capacitance measurements and determined as ?0.350 V versus the saturated calomel electrode. CuInS2x Se2?2x liquid junction solar cells are reported that exhibit a long wavelength cutoff in the spectral response matching the EER data.

SciTech Connect (OSTI)

Thin films of the proposed topological insulator LuPdBi-a Heusler compound with the C1{sub b} structure-were prepared on Ta-Mo-buffered MgO(100) substrates by co-sputtering from PdBi{sub 2} and Lu targets. Epitaxial growth of LuPdBi films was confirmed by X-ray diffraction and reflection high-energy electron diffraction. The root-mean-square roughness of the films was as low as 1.45 nm, even though the films were deposited at high temperature. The film composition is close to the ideal stoichiometric ratio. The valence band spectra of the LuPdBi films, observed by hard X-ray photoelectron spectroscopy, correspond very well with the ab initio-calculated density of states.

Magnetic and electrical properties of layered magnets Tl(Cr,Mn,Co)Se{sub 2}  

SciTech Connect (OSTI)

Tl(Cr,Mn,Co)Se{sub 2} crystals were synthesized at T {approx} 1050 K. X-ray diffraction analysis showed that TlCrSe{sub 2}, TlMnSe{sub 2}, and TlCoSe{sub 2} compounds crystallize in the hexagonal crystal system with the lattice parameters: a = 3.6999 A, c = 22.6901 A, c/a {approx} 6.133, z = 3, {rho}{sub x} = 6.209 g/cm{sup 3}; a = 6.53 A, c = 23.96 A, c/a {approx} 3.669, z = 8, {rho}{sub x} = 6.71 g/cm{sup 3}; and a = 3.747 A, c = 22.772 A, c/a {approx} 6.077, z = 3, {rho}{sub x} = 7.577 g/cm{sup 3}, respectively. Magnetic and electrical studies in the temperature range from 80-400 K showed that TlCrSe{sub 2} is a semiconductor ferromagnet, TlMnSe{sub 2} is a semiconductor antiferromagnet, and TlCoSe{sub 2} is a ferrimagnet with a conductivity characteristic of metals. A rather large deviation in the experimental effective magnetic moment for TlCrSe{sub 2} (3.05 {mu}B) from the theoretical value (3.85 {mu}B) is attributed to two-dimensional magnetic ordering in the paramagnetic region of the noticeably layered ferromagnet TlCrSe{sub 2}. In TlCrSe{sub 2}, a correlation between magnetic and electrical properties was detected.

Improved thermoelectric performance in polycrystalline p -type Bi 2 Te 3 via an alkali metal salt hydrothermal nanocoating treatment approach  

Science Journals Connector (OSTI)

We report herein a proof-of-principle study of grain boundary engineering in the polycrystalline p -type Bi 2 Te 3 system. Utilizing the recently developed hydrothermal nanocoating treatment technique we fabricated an alkali-metal(s)-containing surface layer on the p -Bi 2 Te 3 bulk grain which in turn became part of the grain boundary upon hot pressing densification. Compared to the untreated bulk reference the dimensionless figure of merit Z T has been improved by ? 30 % in the Na-treated sample chiefly due to the reduced thermal conductivity and ? 38 % in the Rb-treated sample mainly owing to the improved power factor. The grain boundary phase provides a new avenue by which one can potentially decouple the otherwise inter-related electrical resistivity Seebeck coefficient and thermal conductivity within one thermoelectric material.

Temperature dependent photoexcited carrier dynamics in multiferroic BiFeO{sub 3} film: A hidden phase transition  

SciTech Connect (OSTI)

The ultrafast carrier dynamics of the multiferroic BiFeO{sub 3} film in a broad temperature range is investigated using optical pump-probe spectroscopy. The photoexcited electrons release their energy with optical phonons emission through electron-phonon coupling in about 1 ps. The following intermediate process is identified as dynamical spin-lattice coupling in several picoseconds. Furthermore, the peak values of the optical reflectivity and the time constants of carrier relaxation channels show significant changes while the temperature varies from 137.5?K to around 195?K, this aligns with the previously reported hidden phase transition. Our study demonstrates that ultrafast spectroscopy is a sensitive method to look into the dynamical interactions among the on-site high-energy electrons accumulated in the p conduction band of Bi, coherent optical phonon, as well as the spin degree of freedom. These features play crucial roles in the characterization of phase transitions.

Insulation coating of silver tapes using an organometallic solution of Zr and Ca for application to Bi-based superconductors  

Science Journals Connector (OSTI)

Silver tapes were spray coated using an organometallic solution as the carrier liquid. When this solution was annealed in air at 825 °C, ~4% of its total weight remained as CaZrO3. Mixtures of Bi2O3, SrCO3 and CaCO3 have been prepared with seven different stoichiometries. An organometallic solution was mixed with ceramic oxide powders and spray coated onto silver tapes. Electrical insulation tests were performed applying a dc potential, and insulation survived more than 30 V. Coated tapes were coiled to progressively decreasing diameters down to 1 mm diameter with no sign of cracking, indicating the possibility of metallic bonding and diffusion. This technique appears to be suitable for use in the insulation of Bi-based superconducting tapes and wires, since it does not contain any element that is chemically reactive to this system.

Magnetoresistance and electronic structure of the half-metallic ferrimagnet BiCu3Mn4O12  

Science Journals Connector (OSTI)

A cubic ordered perovskite BiCu3Mn4O12 has been synthesized under 6GPa and 1000°C. BiCu3Mn4O12 is a ferrimagnet with TC=350K and its saturated magnetic moment is 10.5?B?f.u. The material showed low-resistive metallic behavior and magnetoresistance (MR) below TC. Its MR was observed over a wide temperature range, and the low-field MR reached ?28% at 5K. An electronic structure calculation revealed that it had a half-metallic nature and that the large MR observed under a low magnetic field was attributed to a spin-polarized tunneling or spin-dependent scattering effect at grain boundaries.

InGaAsBi alloys on InP for efficient near- and mid-infrared light emitting devices  

SciTech Connect (OSTI)

We present the band parameters such as band gap, spin-orbit splitting energy, band offsets and strain of InGaAsBi on InP based on recent experimental data. It is shown that InGaAsBi is promising for near- and mid-infrared photonic devices operating from 0.3–0.8?eV (1.5–4??m) on conventional InP substrates. We also show how bismuth may be used to form alloys whereby the spin-orbit splitting energy (?{sub SO}) is large and controllable and can, for example, be made larger than the band gap (E{sub g}) thereby providing a means of suppressing non-radiative hot-hole producing Auger recombination and inter-valence band absorption both involving the spin-orbit band. This is expected to improve the high-temperature performance and thermal stability of light emitting devices.

Directed Assembly of Bi Metallic Nanoparticles by Pulsed Laser Induced Dewetting: a Unique Nanoscale Time and Length Scale Regime  

SciTech Connect (OSTI)

Pulsed laser induced dewetting (PLiD) was used to assemble patterned, nanoscale metallic thin film features into bi metallic nanoparticles. The liquid-phase flow is related to a conventional droplet impact test and in appropriate dimensions have inertial and viscoinertial flow characteristics. The final size, morphology, composition, and inter-diffusion of the nanoparticles is governed by the interplay of capillary, inertial and viscous forces and an appropriate dimensional regime defined by competing Rayleigh-Plateau and spinodal instabilities.

Performance of Anode-Supported Solid Oxide Fuel Cell with Thin Bi-Layer Electrolyte by Pulsed Laser Deposition  

SciTech Connect (OSTI)

Anode-supported yttria stabilized zirconia (YSZ)/samaria doped ceria (SDC) bi-layer electrolytes with uniform thickness and high density were fabricated by pulsed laser deposition at 1000 degrees C. Fuel cells with such bi-layer electrolytes were fabricated and tested, yielding open circuit voltages from 0.94 to 1.0 V at 600-700 degrees C. Power densities from 0.4 to 1.0 W cm{sup -2} at 0.7 V were achieved in air at temperatures of 600-700 degrees C. Cell performance was improved in flowing oxygen, with an estimated peak power density of over 2 W cm{sup -2} at 650 degrees C, assuming the same overall resistance over the entire range of current density. The high cell performance was attributed to the very low ohmic resistance of the fuel cell, owing to the small thickness of the electrolyte. Stable performance was also demonstrated in that the voltage of the fuel cell showed very little change at a constant current density of 1 A cm{sup -2} during more than 400 hours of operation at 650 degrees C in flowing oxygen. SEM analysis of the fuel cell after testing showed that the bi-layer electrolyte had retained its chemical and mechanical integrity.

RESPONSE OF BI-LEVEL AND RANDOM COPOLYMER BRUSHES BASED ON POLY(N-ISOPROPYLACRYLAMIDE) AND POLY(METHACRYLIC ACID)  

SciTech Connect (OSTI)

Because conformations and interactions are intimately linked, the rich phase behavior exhibited by multicomponent polymer-modified interfaces, and in particular multicomponent polymer brushes, offers new opportunities for manipulating interfacial properties. Despite the widespread use of a variety of grafting to and grafting from approaches for making polymer brushes, there are few reports of synthesis and responsive behavior of stratified block copolymer brushes. In this presentation we describe our efforts to create bi-level and random copolymer brushes consisting of poly(N-isopropylacrylamide) and poly(methacrylic acid) using surface initiated, photoiniferter-mediated photopolymerization. Pre-addition of a source of deactivating radicals combined with judicious choice of photopolymerization conditions enables the formation of bi-level brushes. In situ, multi-angle ellipsometry measurements show that the blocks of the bi-level brushes actuate independently to changes in pH and temperature, but respond in concert to changes in ionic strength. Efforts to examine the nanoscale structure of these systems as a function of pH and temperature using neutron reflectometry will also be highlighted.

Polymorphism and optical properties in [NH{sub 4}][InSe{sub 2}  

SciTech Connect (OSTI)

The solvothermal synthesis and characterization of two indium selenides with stoichiometry [NH{sub 4}][InSe{sub 2}] is described. Yellow [NH{sub 4}][InSe{sub 2}] (1), which exhibits a layered structure, was initially prepared in an aqueous solution of trans-1,4-diaminocyclohexane, and subsequently using a concentrated ammonia solution. A red polymorph of one-dimensional character, [NH{sub 4}][InSe{sub 2}] (2), was obtained using 3,5-dimethylpyridine as solvent. [NH{sub 4}][InSe{sub 2}] (1) crystallizes in the non-centrosymmetric space group Cc (a=11.5147(6), b=11.3242(6), c=15.9969(9) Å and ?=100.354(3)°). The structural motif of the layers is the In{sub 4}Se{sub 10} adamantane unit, composed of four corner-linked InSe{sub 4} tetrahedra. These units are linked by their corners, forming [InSe{sub 2}]{sup ?} layers which are stacked back to back along the c-direction, and interspaced by [NH{sub 4}]{sup +}cations. The one-dimensional polymorph, (2), crystallizes in the tetragonal space group, I4/mcm (a=8.2519(16), c=6.9059 (14) Å). This structure contains infinite chains of edge-sharing InSe{sub 4} tetrahedra separated by [NH{sub 4}]{sup +} cations. - Graphical abstract: Two polymorphic forms of [NH{sub 4}][InSe{sub 2}], which are yellow and red, have been prepared and their optical properties investigated. Highlights: • Two new indium selenides prepared by a solvothermal method. • Depending on synthesis conditions, two polymorphic forms of [NH{sub 4}][InSe{sub 2}] prepared. • Layered polymorph contains In{sub 4}Se{sub 10} adamantane clusters, linked by their corners. • One-dimensional polymorph contains [InSe{sub 2}]{sup ?} chains of edge-sharing tetrahedra. • Non-centrosymmetric layered polymorph shows a second harmonic generation response.

Characterization of ZnSe scintillating bolometers for Double Beta Decay  

E-Print Network [OSTI]

ZnSe scintillating bolometers are good candidates for future Double Beta Decay searches, because of the 82Se high Q-value and thanks to the possibility of alpha background rejection on the basis of the scintillation signal. In this paper we report the characteristics and the anomalies observed in an extensive study of these devices. Among them, an unexpected high emission from alpha particles, accompanied with an unusual pattern of the light vs. heat scatter plot. The perspectives for the application of this kind of detectors to search for the Neutrinoless Double Beta Decay of 82Se are presented.

Interband electronic transitions and phase transformation of multiferroic Bi{sub 1?x}La{sub x}Fe{sub 1?y}Ti{sub y}O{sub 3} ceramics revealed by temperature-dependent spectroscopic ellipsometry  

SciTech Connect (OSTI)

Optical properties and phase transition of Bi{sub 1?x}La{sub x}Fe{sub 1?y}Ti{sub y}O{sub 3} (BLFTO) ceramics with different composition (0.02???x???0.10, 0.01???y???0.06) have been investigated by spectroscopic ellipsometry (SE) in the temperature range of ?70–450?°C. The real part of the complex dielectric function ?{sub 1} increases with the temperature. Meanwhile, the imaginary part ?{sub 2} in the low-energy region decreases with the temperature and has an opposite trend in the high-energy side. Four typical interband transitions (E{sub a} ? 2.50?eV, E{sub b} ? 2.70?eV, E{sub c} ? 3.60?eV, and E{sub d} ? 4.25?eV) can be observed from the second derivative of the complex dielectric functions with aid of the standard critical point model. The critical point (CP) transition becomes broadening and shifts to a lower energy side as La and Ti compositions increase. Moreover, the CP transition energies show a red-shift trend with increasing the temperature until 320?°C, due to the lattice thermal expansion and electron-phonon interaction. The typical interband transitions and partial spectral weight present anomalies in the proximity of antiferromagnetic transition owing to the coupling between magnetic and ferroelectric order parameters and spin-lattice coupling for BLFTO multiferroic materials. It was found that the Néel temperature of BLFTO ceramics decreases from 364 to 349?°C with increasing doping composition of La and Ti elements. These phenomena can be attributed to the modification of electronic structure and magnetic order because the differences of electronegativity and ionic radii between Bi and La, Fe and Ti induce the variations on the bond angle and bond length between cations and anions. Moreover, the substitution for magnetic Fe{sup 3+} ions with nonmagnetic Ti{sup 4+} ions can reduce the exchange interaction between adjacent magnetic moments. Therefore, SE technique can be sensitive for detecting the phase/structural transitions of multiferroic oxides.

Bi-conformal symmetry and static Green functions in the Schwarzschild-Tangherlini spacetimes  

E-Print Network [OSTI]

We study static massless minimally coupled scalar field created by a source in a static D-dimensional spacetime. We demonstrate that the corresponding equation for this field is invariant under a special transformation of the background metric. This transformation consists of the static conformal transformation of the spatial part of the metric accompanied by a properly chosen transformation of the red-shift factor. Both transformations are determined by one function of the spatial coordinates. We show that in a case of higher dimensional spherically symmetric black holes one can find such a bi-conformal transformation that the symmetry of the D-dimensional metric is enhanced after its application. Namely, the metric becomes a direct sum of the metric on a unit sphere and the metric of 2D anti-de Sitter space. The method of the heat kernels is used to find the Green function in this new space, that allows one, after dimensional reduction, to obtain a static Green function in the original space of the static black hole. The general useful representation of static Green functions is obtained in the Schwarzschild-Tangherlini spacetimes of arbitrary dimension. The exact explicit expressions for the static Green functions are obtained in such metrics for D Green function coincides with the Copson solution.

Dust-ion-acoustic Gardner solitons in a dusty plasma with bi-Maxwellian electrons  

SciTech Connect (OSTI)

The nonlinear propagation of dust-ion-acoustic (DIA) waves in a dusty plasma with bi-Maxwellian electrons, namely, lower and higher temperature electrons (composed of negatively charged stationary dust, inertial ions, and non-inertial two-temperature-electrons) is investigated by deriving the Gardner equation using the reductive perturbation technique. The basic features (amplitude, width, etc.) of the hump (positive potential) and dip (negative potential) shaped DIA solitons (Gardner solitons, i.e., GSs) are found to exist beyond the Korteweg-de Vries (K-dV) limit. These DIA-GSs are qualitatively different from the K-dV and modified K-dV solitons. It is also shown that depending on the parameter {sigma} (where {sigma}=T{sub e1}/T{sub e2}, T{sub e1} and T{sub e2} being the temperatures of two distinct electrons and T{sub e1} Much-Less-Than T{sub e2}), the DIA-GSs exhibit hump and dip shape solitary structures. The implications of our results in understanding the localized nonlinear electrostatic perturbations observed in double-plasma machines, rf discharge plasma, noctilucent cloud region in Earths atmosphere, etc., where population of two thermal electrons can significantly dominate the wave dynamics, are also briefly addressed.

Design of a high-current downlink using Bi-based superconductors  

SciTech Connect (OSTI)

Recent processing developments in Bi{sub 1.8}Pb{sub 0.4}Sr{sub 2}Ca{sub 2}Cu{sub 3}0{sub x} (BSCCO-2223) bars have produced bulk BSCCO-2223 bars with properties advantageous for power applications. Cold isostatically pressed (CIP) and sinter-forged BSCCO-2223 both have low AC loss, which make them desirable for use in power devices. Thermal conductivity of the CIP bars is lower than that of the previously used sinter-forged samples by a factor of 2. CIP bars with cross-sectional areas of =0.75 cm{sup 2} and carrying 250 A RMS transport current have AC loss values of 30 pJ/cycle-cm at 50 Hz and 77 K. A pair of prototype downlinks were designed and built with sinter forged bars to deliver a continuous AC current of 1500 A over a temperature gradient of 77 to 4.2 K while delivering about -200 MW of heat to the liquid-helium-cooled end. This paper will discuss the design considerations and modeling of downlinks, which supply high AC currents over the 77 to 4.2 K temperature gradient with low thermal losses.

Synthesis and structural characterization of new dithiocarbamate complexes from Sb(III) and Bi(III)  

SciTech Connect (OSTI)

Twenty new antimony and bismuth dithiocarbamate complexes which employed ten different type of amines have been successfully synthesized.

Low-temperature photoacoustic spectra of BiI3 single crystals  

Science Journals Connector (OSTI)

The photoacoustic (PA) spectra of layer halide BiI3 has been studied by a piezoelectric transducer as a detector in the temperature region from 115 K to room temperature. Four peaks of G (1.97 eV), A (2.03 eV), B (2.17 eV), and C (2.38 eV) are observed in the PA spectra at 115 K. Peaks A and B are explained by the transition of the ground and the first excited states of the direct exciton. The onset of the transitions from the spin-orbit split valence band occurs at peak C. The decrease of the PA signal which begins at peak C is interpreted by the generation of the different pathways for the relaxation of the excited carriers. Since the intensity of the peak G varies from sample to sample and the peak has not been observed in the photoluminescence measurements, the origin of the peak G is attributed to the nonradiative transitions of the extrinsic centers. This capability to observe the nonradiative-decay processes is one of the chief advantages for the PA measurements.

Thermoelectric properties of polycrystalline In4Se3 and In4Te3  

SciTech Connect (OSTI)

High thermoelectric performance of a single crystal layered compound In{sub 4}Se{sub 3} was reported recently. We present here an electrical and thermal transport property study over a wide temperature range for polycrystalline samples of In{sub 4}Se{sub 3} and In{sub 4}Te{sub 3}. Our data demonstrate that these materials are lightly doped semiconductors, leading to large thermopower and resistivity. Very low thermal conductivity, below 1 W/m K, is observed. The power factors for In{sub 4}Se{sub 3} and In{sub 4}Te{sub 3} are much smaller when compared with state-of-the-art thermoelectric materials. This combined with the very low thermal conductivity results in the maximum ZT value of less than 0.6 at 700 K for In{sub 4}Se{sub 3}.

Empty 4f1-State Magneto-Optical Spectroscopy in LaSe  

Science Journals Connector (OSTI)

We report the first observation of the magneto-optical signal of an empty spin-polarized 4f state in a paramagnetic metal. At 1.5 K and in a magnetic field of 10 T the Kerr rotation spectrum of LaSe shows a remarkably sharp positive peak of 2.1° at 2.77 eV and a broader and smaller structure at 3.01 eV. A comparison with CeSe, which displays a similar sharp peak with opposite sign but no second peak, gives evidence that the LaSe signal is due to 5d?4f (J=5/2) and 5d?4f (J=7/2) transitions, while the magneto-optical signal in CeSe corresponds to a 4f (J=5/2)?5d transition.

Donor bound excitons in ZnSe nanoresonators - Applications in quantum information science  

SciTech Connect (OSTI)

Here we summarize the advantages of excitons bound to isolated fluorine donor in ZnSe/ZnMgSe quantum well nano-structures. Devices based on these semiconductors, are particularly suited to implement concepts of the optical manipulation of quantum states in solid-state material. The fluorine donor in ZnSe provides a physical qubit with potential advantages over previously researched qubits. In this context we show several initial demonstrations of devices, such as a low-threshold microdisk laser and an indistinguishable single photon source. Additionally we demonstrate the realization of a controllable three-level-system qubit consisting of a single Fluorine donor in a ZnSe nano-pillar, which provides an optical accessible single electon spin qubit.

Breast Imaging Reporting and Data System (BI-RADS) breast composition descriptors: Automated measurement development for full field digital mammography  

SciTech Connect (OSTI)

Purpose: The Breast Imaging Reporting and Data System (BI-RADS) breast composition descriptors are used for standardized mammographic reporting and are assessed visually. This reporting is clinically relevant because breast composition can impact mammographic sensitivity and is a breast cancer risk factor. New techniques are presented and evaluated for generating automated BI-RADS breast composition descriptors using both raw and calibrated full field digital mammography (FFDM) image data.Methods: A matched case-control dataset with FFDM images was used to develop three automated measures for the BI-RADS breast composition descriptors. Histograms of each calibrated mammogram in the percent glandular (pg) representation were processed to create the new BR{sub pg} measure. Two previously validated measures of breast density derived from calibrated and raw mammograms were converted to the new BR{sub vc} and BR{sub vr} measures, respectively. These three measures were compared with the radiologist-reported BI-RADS compositions assessments from the patient records. The authors used two optimization strategies with differential evolution to create these measures: method-1 used breast cancer status; and method-2 matched the reported BI-RADS descriptors. Weighted kappa (?) analysis was used to assess the agreement between the new measures and the reported measures. Each measure's association with breast cancer was evaluated with odds ratios (ORs) adjusted for body mass index, breast area, and menopausal status. ORs were estimated as per unit increase with 95% confidence intervals.Results: The three BI-RADS measures generated by method-1 had ? between 0.25–0.34. These measures were significantly associated with breast cancer status in the adjusted models: (a) OR = 1.87 (1.34, 2.59) for BR{sub pg}; (b) OR = 1.93 (1.36, 2.74) for BR{sub vc}; and (c) OR = 1.37 (1.05, 1.80) for BR{sub vr}. The measures generated by method-2 had ? between 0.42–0.45. Two of these measures were significantly associated with breast cancer status in the adjusted models: (a) OR = 1.95 (1.24, 3.09) for BR{sub pg}; (b) OR = 1.42 (0.87, 2.32) for BR{sub vc}; and (c) OR = 2.13 (1.22, 3.72) for BR{sub vr}. The radiologist-reported measures from the patient records showed a similar association, OR = 1.49 (0.99, 2.24), although only borderline statistically significant.Conclusions: A general framework was developed and validated for converting calibrated mammograms and continuous measures of breast density to fully automated approximations for the BI-RADS breast composition descriptors. The techniques are general and suitable for a broad range of clinical and research applications.

Pulsed Laser Deposition of Photoresponsive Two-Dimensional GaSe Nanosheet Networks  

SciTech Connect (OSTI)

Here we explore pulsed laser deposition (PLD), a well known and versatile synthesis method principally used for epitaxial oxide thin film growth, for the synthesis of functional metal chalcogenide (GaSe) nanosheet networks by stoichiometric transfer of laser vaporized material from bulk GaSe targets in Ar background gas. Uniform coverage of interconnected, crystalline, few-layer, photoresponsive GaSe nanosheets in both in-plane and out-of-plane orientations were achieved under different ablation plume conditions over ~1.5 cm2 areas. Plume propagation was characterized by in situ ICCD-imaging. High (1 Torr) Ar background gas pressures were found to be crucial for the stoichiometric growth of GaSe nanosheet networks. Individual 1-3 layer GaSe triangular nanosheets of ~ 200 nm domain size were formed within 30 laser pulses, coalescing to form nanosheet networks in as few as 100 laser pulses. The thickness of the deposited networks increased linearly with pulse number, adding layers in a two-dimensional (2D) growth mode while maintaining a surface roughness of 2 GaSe layers for increasing overall thickness. Field effect transistors using these interconnected crystalline GaSe networks showed p-type semiconducting characteristics with mobilities reaching as high as 0.1 cm2V-1s-1. Spectrally-resolved photoresponsivities and external quantum efficiencies ranged from 0.4 AW-1 and 100% at 700 nm, to 1.4 AW-1 and 600 % at 240 nm, respectively. Pulsed laser deposition under these conditions appears to provide a versatile and rapid approach to stoichiometrically transfer and deposit photoresponsive networks of 2D nanosheets with digital thickness control and substrate-scale uniformity for a variety of applications.

Absorption and spectra of optical parameters in amorphous solid solutions of the Se-S system  

SciTech Connect (OSTI)

A study of the optical properties of the Se-S system has revealed a correlation between the dependences of optical absorption coefficient {alpha}, effective concentration of charged defects N{sub t}, and characteristic energy E{sub 0} corresponding to the Urbach optical absorption in the spectral region where the Urbach rule works for the Se-S system on the S concentration. These optical properties are controlled by charged defects. It is shown that concentrations of intrinsic charged defects can be changed by variation in composition of the Se-S system. Reflectance spectra of amorphous solid solutions of the Se-S system are studied within the energy range 1-6 eV. Using the Kramers-Kronig method, spectral dependences of optical constants and derivative optical and dielectric functions are calculated. Variation in the spectra of optical parameters with composition of the Se-S system are explained within a cluster model in which the density of electron states is a function of atomic configurations in clusters, i.e., of the character of a short-range order.

Synthesis of CuInSe2 nanopowders by microwave assisted solvothermal method  

Science Journals Connector (OSTI)

CuInSe2 (CISe) nanopowders were synthesised using the innovative microwave assisted solvothermal method. We studied the impact of the synthesis temperature as well as the precursor composition on the morphological, compositional, and structural properties of the nanopowders. We have found that for the synthesis of stoichiometric CISe particulates with chalcopyrite phase structure, temperatures equal to 230°C and In concentration in excess in the reaction solution with respect to Cu are required. At lower temperatures (200°C) and In excess, the presence of binary phases such as CuxSe and In2Se3 is clearly detected indicating a inadequate In incorporation. At intermediate temperatures (215°C), CISe is mainly formed but preferentially with the Cu-Au polytype structure. The method presented here may be very interesting for the possible mass production of CISe nanopowders due to the facile temperature control, the fast reaction process, and the easy scalability.

Assessment of the SE2-ANL code using EBR-II temperature measurements  

SciTech Connect (OSTI)

The SE2-ANL code is a modified version of the SUPERENERGY-2 code [1]. This code is used at Argonne National Laboratory (ANL) to compute the core-wide temperature profiles in Liquid Metal Reactor (LMR) cores. The accuracy of this code has recently been tested by comparing the predicted temperatures with measured values in the Experimental Breeder Reactor R (EBR-II). The detailed temperature distributions in two experimental subassemblies and the mixed mean subassembly outlet temperatures were used in this validation study. The SE2-ANL predictions were found to agree well with measured values. It was also found that SE2-ANL yields results with accuracy comparable to the more detailed COBRA-WC [2] calculations at much lower computational cost.

Hydrothermal synthesis of [C{sub 6}H{sub 16}N{sub 2}][In{sub 2}Se{sub 3}(Se{sub 2})]: A new one-dimensional indium selenide  

SciTech Connect (OSTI)

A new organically templated indium selenide, [C{sub 6}H{sub 16}N{sub 2}][In{sub 2}Se{sub 3}(Se{sub 2})], has been prepared hydrothermally from the reaction of indium, selenium and trans-1,4-diaminocyclohexane in water at 170 deg. C. This material was characterised by single-crystal and powder X-ray diffraction, thermogravimetric analysis, UV-vis diffuse reflectance spectroscopy, FT-IR and elemental analysis. The compound crystallises in the monoclinic space group C2/c (a=12.0221(16) A, b=11.2498(15) A, c=12.8470(17) A, {beta}=110.514(6){sup o}).

Experimental Cross Sections for Reactions of Heavy Ions and 208Pb, 209Bi, 238U, and 248Cm Targets  

SciTech Connect (OSTI)

The study of the reactions between heavy ions and {sup 208}Pb, {sup 209}Bi, {sup 238}U, and {sup 248} Cm targets was performed to look at the differences between the cross sections of hot and cold fusion reactions. Experimental cross sections were compared with predictions from statistical computer codes to evaluate the effectiveness of the computer code in predicting production cross sections. Hot fusion reactions were studied with the MG system, catcher foil techniques and the Berkeley Gas-filled Separator (BGS). 3n- and 4n-exit channel production cross sections were obtained for the {sup 238}U({sup 18}O,xn){sup 256-x}Fm, {sup 238}U({sup 22}Ne,xn){sup 260-x}No, and {sup 248}Cm({sup 15}N,xn){sup 263-x}Lr reactions and are similar to previous experimental results. The experimental cross sections were accurately modeled by the predictions of the HIVAP code using the Reisdorf and Schaedel parameters and are consistent with the existing systematics of 4n exit channel reaction products. Cold fusion reactions were examined using the BGS. The {sup 208}Pb({sup 48}Ca,xn){sup 256-x}No, {sup 208}Pb({sup 50}Ti,xn){sup 258-x}Rf, {sup 208}Pb({sup 51}V,xn){sup 259-x}Db, {sup 209}Bi({sup 50}Ti,xn){sup 259-x}Db, and {sup 209}Bi({sup 51}V,xn){sup 260-x}Sg reactions were studied. The experimental production cross sections are in agreement with the results observed in previous experiments. It was necessary to slightly alter the Reisdorf and Schaedel parameters for use in the HIVAP code in order to more accurately model the experimental data. The cold fusion experimental results are in agreement with current 1n- and 2n-exit channel systematics.

Method of fabricating high-efficiency Cu(In,Ga)(SeS).sub.2 thin films for solar cells  

DOE Patents [OSTI]

A process for producing a slightly Cu-poor thin film of Cu(In,Ga)(Se,S).sub.2 comprises depositing a first layer of (In,Ga).sub.x (Se,S).sub.y followed by depositing just enough Cu+(Se,S) or Cu.sub.x (Se,S) to produce the desired slightly Cu-poor material. In a variation, most, but not all, (about 90 to 99%) of the (In,Ga).sub.x (Se,S).sub.y is deposited first, followed by deposition of all the Cu+(Se,S) or Cu.sub.x (Se,S) to go near stoichiometric, possibly or even preferably slightly Cu-rich, and then in turn followed by deposition of the remainder (about 1 to 10%) of the (In,Ga).sub.x (Se,S).sub.y to end with a slightly Cu-poor composition. In yet another variation, a small portion (about 1 to 10%) of the (In,Ga).sub.x (Se,S).sub.y is first deposited as a seed layer, followed by deposition of all of the Cu+(Se,S) or Cu.sub.x (Se,S) to make a very Cu-rich mixture, and then followed deposition of the remainder of the (In,Ga).sub.x (Se,S).sub.y to go slightly Cu-poor in the final Cu(In,Ga)(Se,S).sub.2 thin film.

Formation of phases in the films of a Ag-In-Se system  

SciTech Connect (OSTI)

Processes of electron-diffraction structure analysis have been used to study the processes of phase formation and phase transitions in thin layers of a Ag-In-Se system. The phases formed at the onset of interaction between the films and phase transformations occurring during annealing of the samples in vacuum are established. It is found that thin films of the AgInSe{sub 2} compound formed as a result of simultaneous or consecutive deposition of components are amorphous, and crystallization brings about the formation of textured films with high structural quality

Note on the relationship between the speed of light and gravity in the bi-metric theory of gravity  

E-Print Network [OSTI]

Relationship between the speed of gravity c_g and the speed of light c_e in the bi-metric theory of gravity is discussed. We reveal that the speed of light is a function of the speed of gravity which is a primary fundamental constant. Thus, experimental measurement of relativistic bending of light propagating in time-dependent gravitational field directly compares the speed of gravity versus the speed of light and tests if there is any aether associated with the gravitational field considered as a transparent `medium' with the constant refraction index.

BiOI nanosheets decorated TiO2 nanofiber: Tailoring water purification performance of photocatalyst in structural and photo-responsivity aspects  

Science Journals Connector (OSTI)

Abstract Microscopic structure and photo-responsive characters are two important facets that dominate the synthetic performance of photocatalysts in environment remediation. In the present investigation, we report the simultaneous tailoring of these two facets toward improving the water purification performance of TiO2 based photocatalyst. Electrospinning-derived TiO2 nanofibers were decorated with the visible-light responsive BiOI nanosheets via a simple hydrothermal reaction approach, constructing heterostructured composite fibers. The obtained hierarchical TiO2@BiOI fibers demonstrated improved reactivity toward decomposition of Rhodamine B in the visible-light range over the pristine TiO2 nanofibers, meanwhile possessed high recycling convenience. The mechanism for advancement of the photocatalytic reactivity of the TiO2@BiOI fibers was elucidated by analyzing the results of photoluminescence and transient photocurrent response.

Photovoltaic effect of a bilayer thin film with (Na0.5Bi0.5)1?xBaxTiO3/BiFeO3 heterostructure  

Science Journals Connector (OSTI)

A bilayer film containing (Na0.5Bi0.5)1?xBaxTiO3 (NBT–BT)/BiFeO3(BFO) heterostructure was produced by chemical solution deposition. An enhancement of photovoltaic performance of the bilayer film was discovered. It leads to a short circuit current density of 18.9 µA cm?2 and an open circuit voltage of 0.5 V, these values are much higher than that of BFO film. When transparent indium tin oxide (ITO) was used to substitute gold (Au) as top electrode, the photovoltaic voltage and photocurrent density, respectively, improved to ~0.71 V and ~45 µA cm?2. A theoretical band diagram model considering the ferroelectric polarization, heterostructure on the interface, and energy band bending effect was constructed to depict the mechanism of photovoltaic enhancement of the bilayer film. Temperature-dependent I–V measurements were carried out to explore the barrier height of the Au/BFO/NBT–BT/FTO heterostructure, and a total barrier height of 0.54 eV was obtained. Our work opens up a promising new method that has the potential for enhancing the photovoltaic performance for ferroelectric thin film, and provides deeper understanding of the photovoltaic mechanism of ferroelectric films.

Ferroelectric and ferromagnetic properties of epitaxial BiFeO{sub 3}-BiMnO{sub 3} films on ion-beam-assisted deposited TiN buffered flexible Hastelloy  

SciTech Connect (OSTI)

Growth of multifunctional thin films on flexible substrates is of great technological significance since such a platform is needed for flexible electronics. In this study, we report the growth of biaxially aligned (BiFeO{sub 3}){sub 0.5}:(BiMnO{sub 3}){sub 0.5} [BFO-BMO] films on polycrystalline Hastelloy by using a biaxially aligned TiN as a seed layer deposited by ion-beam-assisted deposited and a La{sub 0.7}Sr{sub 0.3}MnO{sub 3} (LSMO) as a buffer layer deposited by pulsed laser deposition. The LSMO is used not only as a buffer layer but also as the bottom electrode of the BFO-BMO films. X-ray diffraction showed that the BFO-BMO films are biaxially oriented along both in-plane and out-of-plane directions. The BFO-BMO films on flexible metal substrates showed a polarization of 22.9??C/cm{sup 2}. The magnetization of the BFO-BMO/LSMO is 62?emu/cc at room temperature.

Spray Deposition of High Quality CuInSe2 and CdTe Films: Preprint  

SciTech Connect (OSTI)

A number of different ink and deposition approaches have been used for the deposition of CuInSe2 (CIS), Cu(In,Ga)Se2 (CIGS), and CdTe films. For CIS and CIGS, soluble precursors containing Cu, In, and Ga have been developed and used in two ways to produce CIS films. In the first, In-containing precursor films were sprayed on Mo-coated glass substrates and converted by rapid thermal processing (RTP) to In2Se3. Then a Cu-containing film was sprayed down on top of the In2Se3 and the stacked films were again thermally processed to give CIS. In the second approach, the Cu-, In-, and Ga-containing inks were combined in the proper ratio to produce a mixed Cu-In-Ga ink that was sprayed on substrates and thermally processed to give CIGS films directly. For CdTe deposition, ink consisting of CdTe nanoparticles dispersed in methanol was prepared and used to spray precursor films. Annealing these precursor films in the presence of CdCl2 produced large-grained CdTe films. The films were characterized by x-ray diffraction (XRD) and scanning electron microscopy (SEM). Optimized spray and processing conditions are crucial to obtain dense, crystalline films.

Size effect on the electronic and optical band gap of CdSe QD  

SciTech Connect (OSTI)

Present paper deals with a critical and comprehensive analysis of the dependence of photo emission (PE) electronic band gap and optical absorption (OA) excitonic band gap on the size of CdSe QD, via connecting it with excitonic absorbance wavelength. Excitonic absorbance wavelength is determined through an empirical fit of established experimental evidences. Effective excitonic charge and Bohr radius is determined as a function of size. Increase in size of the CdSe QD results in greater Bohr radius and smaller effective excitonic charge. Excitonic binding energy as a degree of size of QD is also calculated which further relates with the difference in PE electronic and OA optical band gaps. It is also shown that with increase in size of CdSe QD, the excitonic binding energy decreases which consequently increases differences in two band gaps. Our results are very well comparable with the established results. Explanation for the origin of the unusual optical properties of CdSe QD has been also discussed.

Enhanced quality thin film Cu(In,Ga)Se.sub.2 for semiconductor device applications by vapor-phase recrystallization  

DOE Patents [OSTI]

Enhanced quality thin films of Cu.sub.w (In,Ga.sub.y)Se.sub.z for semiconductor device applications are fabricated by initially forming a Cu-rich, phase-separated compound mixture comprising Cu(In,Ga):Cu.sub.x Se on a substrate to form a large-grain precursor and then converting the excess Cu.sub.x Se to Cu(In,Ga)Se.sub.2 by exposing it to an activity of In and/or Ga, either in vapor In and/or Ga form or in solid (In,Ga).sub.y Se.sub.z. Alternatively, the conversion can be made by sequential deposition of In and/or Ga and Se onto the phase-separated precursor. The conversion process is preferably performed in the temperature range of about 300.degree.-600.degree. C., where the Cu(In,Ga)Se.sub.2 remains solid, while the excess Cu.sub.x Se is in a liquid flux. The characteristic of the resulting Cu.sub.w (In,Ga).sub.y Se.sub.z can be controlled by the temperature. Higher temperatures, such as 500.degree.-600.degree. C., result in a nearly stoichiometric Cu(In,Ga)Se.sub.2, whereas lower temperatures, such as 300.degree.-400.degree.

The highest ZT of 1.11 at 800 K is obtained for the Co{sub 4}Sb{sub 11.3}Te{sub 0.58}Se{sub 0.12} sample. -- Abstract: A series of double-substituted Co{sub 4}Sb{sub 11.3}Te{sub 0.7?x}Se{sub x} skutterudites have been fabricated by combining the solid state reaction and the spark plasma sintering method, and the effects of Se substitution on the thermoelectric properties are characterized by measurements of the electrical conductivity, the Seebeck coefficient and the thermal conductivity in the temperature range of 300–800 K. Doping Se into the Co{sub 4}Sb{sub 11.3}Te{sub 0.7?x}Se{sub x} matrix suppresses the carrier concentration, and the electrical conductivity actually decreases with the Se content. However, moderate Se doping is effective in enhancing the thermoelectric performance of the n-type Co{sub 4}Sb{sub 11.3}Te{sub 0.7?x}Se{sub x}, because of the resulted dramatically decreased thermal conductivity. Analyses indicate that the heightened point-defect scattering induced by Se doping together with the electron–phonon scattering induced by Te doping is responsible for the reduction of lattice thermal conductivity of these compounds.

Optical transitions in MnGa{sub 2}Se{sub 4}  

SciTech Connect (OSTI)

The dependence of the absorption coefficient on incident photon energy in a MnGa{sub 2}Se{sub 4} single crystal has been investigated in the temperature range 110-295 K. Using group-theory analysis of the electron state symmetry and comparison of the symmetry of the energy spectrum of MnGa{sub 2}Se{sub 4} and its isoelectronic analogs, a conclusion about the character of optical transitions has been drawn. It is shown that the features observed at 2.31 and 2.45 eV are related to the intracenter transitions {sup 6}A{sub 1}{sup 1} {yields} {sup 4}T{sub 2}({sup 4}G) and {sup 6}A{sub 1}{sup 2} {yields} {sup 4}T{sub 2}({sup 4}G). The {sup 6}A{sub 1} state is split by the crystal field.

Modified magnetism within the coherence volume of superconducting FeSeTe  

SciTech Connect (OSTI)

Neutron Scattering is used to probe magnetic interactions as superconductivity develops in opti- mally doped Fe_(1+ )Se_xTe_(1 x). Applying the first moment sum-rule to comprehensive neutron scatter- ing data, we extract the change in magnetic exchange energy [J_(R-R ) S_R S_R ] in the superconducting state referenced to the normal state. Oscillatory changes are observed for Fe-Fe displacements | R| < , where = 1.3(1) nm is the superconducting coherence length. Dominated by a large reduction in the second nearest neighbor exchange energy (-1.2(2) meV/Fe), the overall reduction in magnetic interaction energy is Hmag = 0.31(9) meV/Fe. Comparison to the superconducting condensation energy E_sc = 0.013(1) meV/Fe, which we extract from specific heat data, suggests the modified magnetism we probe drives superconductivity in Fe_(1+ )Se_xTe_(1 x)

Synthesis and thermoelectric properties of Cu excess Cu2ZnSnSe4  

SciTech Connect (OSTI)

Quaternary stannites with an excess of copper were successfully synthesized by reacting the constituent elements and subsequent solid state annealing, followed by densification by hot-pressing. The composition for each specimen was confirmed with a combination of Rietveld refinement and elemental analysis. Their high temperature thermoelectric properties were measured from 300 K to 800 K and compared with that of Cu2ZnSnSe4. The thermal conductivity decreases significantly with increasing Cu content at elevated temperatures due to the crystal structure of this material system. A maximum ZT value of 0.86 was obtained at 800 K for the specimen with the highest Cu content, Cu2.2Zn0.8SnSe4.

Optical nonlinear absorption characteristics of Sb{sub 2}Se{sub 3} nanoparticles  

SciTech Connect (OSTI)

In this work, we report for the first time, the nonlinear optical absorption properties of antimony selenide (Sb{sub 2}Se{sub 3}) nanoparticles synthesized through solvothermal route. X-ray diffraction results revealed the crystalline nature of the nanoparticles. Electron microscopy studies revealed that the nanoparticles are in the range of 10 - 40 nm. Elemental analysis was performed using EDAX. By employing open aperture z-scan technique, we have evaluated the effective two-photon absorption coefficient of Sb{sub 2}Se{sub 3} nanoparticles to be 5e-10 m/W at 532 nm. These nanoparticles exhibit strong intensity dependent nonlinear optical absorption and hence could be considered to have optical power limiting applications in the visible range.

Electroluminescent and current–voltage characteristics of the developed hybrid device with the turn-on voltage of 5.5 V and the radiation wavelength of 515 nm have been obtained. Semiconductor nanoplatelets like CdSe are attractive for the fabrication of hybrid \\{LEDs\\} with low operating voltages, spectrally pure color and short-wavelength electroluminescence, which is required for RGB devices.

Raman spectra have been obtained on 2H-TaSe2 at room temperature and in the commensurate charge-density-wave, superlattice state. At low temperatures six new low frequency modes are seen having symmetries consistent only with a symmetric, three-charge-density wave. A microscopic model of the lattice dynamics of this state is fitted to the four strongest new Raman lines. These are assigned to amplitude and phase modes of the charge-density wave.

Science Journals Connector (OSTI)

A 0 + state in Se72 at 936 keV has been identified through in-beam measurements with Ge70(?,2n)Se72. The beam-related time distribution of conversion electrons from the 936-keV E0 transition yields a half-life of 19.3±0.4 ns. With a Ge72 target and an ?-beam sweeper the half-life of the 690-keV E0 transition in Ge72 was 404±45 ns. For both transitions identification of the emitting nucleus was obtained from the energy separation of the K and L electrons. The KL intensity ratio was intermediate between the theoretical results of Hager and Seltzer and those of Church and Weneser. The reduced E0 nuclear matrix elements are ?=(0.304±0.003)(1-5.01×10-3f) and ?=0.095±0.005 for Se72 and Ge72, respectively, which are 0.77 (for f?40) and 0.24, respectively, of Wilkinson's suggested single-particle unit for E0 matrix elements.

We report the photoacoustic investigations of the Zn1-xCoxSe system. The qualitative analysis of possible nonradiative deexcitation paths in the Co2+ ion is performed. It is shown that the pseudo-Jahn-Teller effect is responsible for accumulation of the electron-lattice interaction energy in the lowest 2T1 state. As a result, the effective path for nonradiative deexcitation of the system is opened.

Photoinduced Surface Oxidation and Its Effect on the Exciton Dynamics of CdSe Quantum Dots  

SciTech Connect (OSTI)

With increased interest in semiconductor nanoparticles for use in quantum dot solar cells there comes a need to understand the long-term photostability of such materials. Colloidal CdSe quantum dots (QDs) were suspended in toluene and stored in combinations of light/dark and N{sub 2}/O{sub 2} to simulate four possible benchtop storage environments. CdSe QDs stored in a dark, oxygen-free environment were observed to better retain their optical properties over the course of 90 days. The excited state lifetimes, determined through femtosecond transient absorption spectroscopy, of air-equilibrated samples exposed to light exhibit a decrease in average lifetime (0.81 ns) when compared to samples stored in a nitrogen/dark environment (8.3 ns). A photoetching technique commonly used for controlled reduction of QD size was found to induce energetic trap states to CdSe QDs and accelerate the rate of electron-hole recombination. X-ray absorption near edge structure (XANES) analysis confirms surface oxidation, the extent of which is shown to be dependent on the thickness of the ligand shell.

Bedload transport in SE Asian streams—Uncertainties and implications for reservoir management  

Science Journals Connector (OSTI)

Abstract This paper reviews the current state of knowledge regarding bedload transport in SE Asian streams and presents the results from a case study on bedload transport in a mountain stream in northern Thailand. Together, the review and new data help contextualize the paucity of work done in the region in the face of a rapid increase in development and reservoir building throughout SE Asia. Data from both the reviewed studies and the case study indicate that bedload transport in many SE Asian streams (e.g. catchment areas  4.5 m3 s?1), we believe our upper estimates for bedload variables (25% of the total sediment load; and a yield of 279 Mg Km?2 y?1) provide reasonable upper bounds. Finally, the bulk of bedload transport is episodic in nature, with a higher proportion moved during high energy tropical storms that occur late in the monsoon rainy season, as well as in response to both natural and anthropogenic landscape disturbances. The possibility that bedload proportion could exceed 20–40% for rivers and streams of various sizes reinforces the need for accurate estimates of both bedload and suspended solid loads prior to building dams in the region. Past examples of reservoir closure following rapid infilling possibly stem from underestimating sediment loads, particularly the bedload component, and failing to factor in the very high sediment loads associated with large storm events.

Light Induced Water Oxidation on Cobalt-Phosphate (Co-Pi) Catalyst Modified Semi-Transparent, Porous SiO2-BiVO4 Electrodes  

SciTech Connect (OSTI)

A facile and simple procedure for the synthesis of semi-transparent and porous SiO{sub 2}-BiVO{sub 4} electrodes is reported. The method involves a surfactant assisted metal-organic decomposition at 500 C. An earth abundant oxygen evolution catalyst (OEC), cobalt phosphate (Co-Pi), has been used to modify the SiO{sub 2}-BiVO{sub 4} electrode by electrodeposition (ED) and photoassisted electrodeposition (PED) methods. Modified electrodes by these two methods have been examined for light induced water oxidation and compared to the unmodified SiO{sub 2}-BiVO{sub 4} electrodes by various photoelectrochemical techniques. The PED method was a more effective method of OEC preparation than the ED method as evidenced by an increased photocurrent magnitude during photocurrent-potential (I-V) characterizations. Electrode surfaces catalyzed by PED exhibited a very large cathodic shift (420 mV) in the onset potential for water oxidation. The chopped-light I-V measurements performed at different intervals over 24-hour extended testing under illumination and applied bias conditions show a fair photostability for PED Co-Pi modified SiO{sub 2}-BiVO{sub 4}.

Features of the charge-transport mechanism in layered Bi{sub 2}Te{sub 3} single crystals doped with chlorine and terbium  

SciTech Connect (OSTI)

The temperature dependences (T = 5-300 K) of the resistivity in the plane of layers and in the direction perpendicular to the layers, as well as the Hall effect and the magnetoresistance (H < 80 kOe, T = 0.5-4.2 K) in Bi{sub 2}Te{sub 3} single crystals doped with chlorine and terbium, are investigated. It is shown that the doping of Bi{sub 2}Te{sub 3} with terbium atoms results in p-type conductivity and in increasing hole concentration. The doping of Bi{sub 2}Te{sub 3} with chlorine atoms modifies also the character of its conductivity instead of changing only the type from p to n. In the temperature dependence of the resistivity in the direction perpendicular to layers, a portion arises with the activation conductivity caused by the hopping between localized states. The charge-transport mechanism in Bi{sub 2}Te{sub 3} single crystals doped with chlorine is proposed.

Surface characterization of ordered intermetallic PtBi(0 0 1) surfaces by ultra-high vacuum–electrochemistry (UHV–EC)  

Science Journals Connector (OSTI)

Surface preparation and characterization of an ordered intermetallic PtBi(0 0 1) single crystal was performed by a combination of surface-sensitive electron spectroscopic techniques under ultra-high vacuum (UHV) conditions and conventional electrochemistry (EC). The atomic concentration of the clean surface was estimated (quantitative Auger analysis) as 54 at% Pt and 46 at% Bi; the LEED pattern exhibited a (1 × 1) structure. These results are in good agreement with expectations for a Pt-terminated PtBi(0 0 1) crystal surface. The electrochemical studies of the clean, well-ordered and smooth PtBi(0 0 1) single crystal were carried out in an H2SO4 supporting electrolyte and indicated that the electrode surface is Pt-terminated with a behavior similar to that of a pure Pt electrode. However, the intermetallic phase was found to be more prone to surface oxidation in the studied potential window (?0.30 V to +1.25 V vs. Ag/AgCl (sat’d NaCl)). Chemisorption of SO 4 2 - / HSO 4 - species was observed at potentials positive of the open circuit potential (OCP). Cycling in a supporting electrolyte gave rise to roughening of the electrode surface. This change is due to the presence of the chemisorbed species on the electrode surface.

Controlling the Carrier Concentration of the High-Temperature Superconductor Bi2Sr2CaCu2O8+? in Angle-resolved Photoemission Spectroscopy Experiments  

SciTech Connect (OSTI)

We study the variation of the electronic properties at the surface of a high-temperature superconductor as a function of vacuum conditions in angle-resolved photoemission spectroscopy experiments. Normally, under inadequate ultrahigh vacuum (UHV) conditions the carrier concentration of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} (Bi2212) increases with time due to the absorption of oxygen from CO{sub 2}/CO molecules that are prime contaminants present in UHV systems. We find that in an optimal vacuum environment at low temperatures, the surface of Bi2212 is quite stable (the carrier concentration remains constant); however at elevated temperatures the carrier concentration decreases due to the loss of oxygen atoms from the Bi-O layer. These two effects can be used to control the carrier concentration in situ. Our finding opens the possibility of studying the electronic properties of the cuprates as a function of doping across the phase diagram on the same surface of sample (i.e., with the same impurities and nondopant defects). We envision that this method could be utilized in other surface sensitive techniques such as scanning tunneling microscopy/spectroscopy.

Synthesis and characterization of rare-earth doped SrBi{sub 2}Nb{sub 2}O{sub 9} phase in lithium borate based nanocrystallized glasses  

SciTech Connect (OSTI)

Glass composites comprising of un-doped and samarium-doped SrBi{sub 2}Nb{sub 2}O{sub 9} nanocrystallites are fabricated in the glass system 16.66SrO-16.66[(1-x)Bi{sub 2}O{sub 3}-xSm{sub 2}O{sub 3}]-16.66Nb{sub 2}O{sub 5}-50Li{sub 2}B{sub 4}O{sub 7} (0<=x<=0.5, in mol%) via the melt quenching technique. The glassy nature of the as-quenched samples is established by differential thermal analyses. Transmission electron microscopic studies reveal the presence of about 15 nm sized spherical crystallites of the fluorite-like SrBi{sub 1.9}Sm{sub 0.1}Nb{sub 2}O{sub 9} phase in the samples heat treated at 530 deg. C. The formation of layered perovskite-type un-doped and samarium-doped SrBi{sub 2}Nb{sub 2}O{sub 9} nanocrystallites with an orthorhombic structure through the intermediate fluorite phase is confirmed by X-ray powder diffraction and micro-Raman spectroscopic studies. The influence of samarium doping on the lattice parameters, lattice distortions, and the Raman peak positions of SrBi{sub 2}Nb{sub 2}O{sub 9} perovskite phase is clarified. The dielectric constants of the perovskite SrBi{sub 2}Nb{sub 2}O{sub 9} and SrBi{sub 1.9}Sm{sub 0.1}Nb{sub 2}O{sub 9} nanocrystals are relatively larger than those of the corresponding fluorite-like phase and the precursor glass. - Graphical Abstract: This figure shows the XRD patterns at room temperature for the as-quenched and heat treated samples in Sm{sub 2}O{sub 3}-doped (x=0.1) glass. Based on these results, it is concluded that the formation of samarium-doped perovskite SBN phase takes place via an intermediate fluorite-like phase in the crystallization of this glass.

We report on the role of oxygen octahedral tilting in the monoclinic-to-tetragonal phase transition in ultra-thin BiFeO{sub 3} films grown on (001) SrTiO{sub 3} substrates. Reciprocal space maps clearly show the disappearance of the integer-order Bragg peak splitting associated with the monoclinic phase when the film thickness decreases below 20 unit cells. This monoclinic-to-tetragonal transition is accompanied by the evolution of the half-order diffraction peaks, which reflects untilting of the oxygen octahedra around the [110] axis, proving that the octahedral tilting is closely correlated with the transition. This structural change is thickness-dependent, and different from a strain-induced transition in the conventional sense.

Does it matter which Life Cycle Assessment (LCA) tool you choose? – a comparative assessment of SimaPro and GaBi  

Science Journals Connector (OSTI)

Abstract SimaPro and GaBi are the leading software tools used for life cycle assessments. Assessing product systems applying the exact same unit process foundation would be expected to yield comparable result sets with either tool. The software performances are compared based on a random sample of 100 unit processes. The research question investigated here is; can there be a difference between SimaPro and GaBi influencing the results and the decisions based on them? In many cases the results are identical between SimaPro and GaBi or nearly so, but in other cases the results reveal differences. Some of these differences are so large that they could influence the conclusions. For some of the 100 unit processes, six elementary flows were inventoried differently in SimaPro and GaBi, with an extreme maximum comparative ratio of 109. The implementation of the impact assessment methodologies shows notable differences. For the same life cycle inventory the maximum result ratio for the characterized results is 0.0076 for Terrestrial Ecotoxicity Potential. The observed differences appear to originate primarily from errors in the software databases for both inventory and impact assessment. SimaPro and GaBi are used by many Life Cycle Assessment (LCA) practitioners worldwide as a decision-support tool; if the results of the present analysis are representative of the differences obtained when using either one or the other, then the implications of this paper are worrying. It is clearly in the interest of both software developers and LCA practitioners that the observed differences be addressed, for example through ring tests comparing the tools.

Single-Neutron Excitations in Neutron-Rich 83Ge and 85Se  

SciTech Connect (OSTI)

The 2H(82Ge,p)83Ge and 2H(84Se,p)85Se reactions were studied with radioactive beams of 82Ge and 84Se at beam energies of Ebeam = 330 and 380 MeV, respectively. Excitation energies, proton angular distributions, and asymptotic normalization coefficients have been determined for the lowest lying states of 83Ge and 85Se. Spectroscopic factors have also been extracted under normal assumptions of the bound-state potential properties in the DWBA analysis. However, the peripheral character of the measurements leads to large uncertainties in this extraction. Shell model calculations have been performed in the region above 78Ni, comparing the single-particle properties of the even-Z, N = 51 nuclei up to 91Zr and including 83Ge and 85Se. Direct-semidirect neutron capture calculations to 83Ge and 85Se have also been performed using the spectroscopic input from these (d,p) reaction measurements.

Effect of radical fluorination on mono- and bi-layer graphene in Ar/F{sub 2} plasma  

SciTech Connect (OSTI)

Fluorinated graphene has the possibility to achieve unique properties and functions in graphene. We propose a highly controlled fluorination method utilizing fluorine radicals in Ar/F{sub 2} plasma. To suppress ion bombardments and improve the reaction with fluorine radicals on graphene, the substrate was placed 'face down' in the plasma chamber. Although monolayer graphene was more reactive than bilayer, fluorination of bilayer reached the level of I{sub D}/I{sub G} {approx} 0.5 in Raman D peak intensity at 532 nm excitation. Annealing fluorinated samples proved reversibility of radical fluorination for both mono- and bi-layer graphenes. X-ray photoelectron spectroscopy showed the existence of carbon-fluorine bonding.

Lightweight PV Inverters: Dual Bi-Directional IGBTs Modules Enables Breakthrough PV Inverter Using Current Modulation Topology  

SciTech Connect (OSTI)

Solar ADEPT Project: PV inverters convert DC power generated by modules into usable AC power. IPC’s initial 30kW 94lb. PV inverter reduces the weight of comparable 30kW PV inverters by 90%—reducing the cost of materials, manufacturing, shipping, and installation. With ARPA-E support, new bi-directional silicon power switches will be developed, commercialized, and utilized in IPC’s next-generation PV inverter. With these components, IPC will produce 100kW inverters that weight less than 100lb., reducing the weight of conventional 3,000lb. 100kW inverters by more than 95%. The new power switches will cut IPC’s $/W manufacturing cost in half, as well as further reduce indirect shipping and installation costs.

Gap-Inhomogeneity-Induced Electronic States in Superconducting Bi2Sr2CaCu2O8+delta  

SciTech Connect (OSTI)

In this Letter, we analyze, using scanning tunneling spectroscopy, the density of electronic states in nearly optimally doped Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} in zero magnetic field. Focusing on the superconducting gap, we find patches of what appear to be two different phases in a background of some average gap, one with a relatively small gap and sharp large coherence peaks and one characterized by a large gap with broad weak coherence peaks. We compare these spectra with calculations of the local density of states for a simple phenomenological model in which a 2{zeta}{sub 0} x 2{zeta}{sub 0} patch with an enhanced or suppressed d-wave gap amplitude is embedded in a region with a uniform average d-wave gap.

Ansatz of Leptonic Mixing: The Alliance of Bi-Maximal Mixing with a Single-Angle Rotation  

E-Print Network [OSTI]

We introduce an ansatz of the PMNS matrix that consists of specific types of transformations. Bi-maximal mixing is taken for the neutrino masses, while a single-angle rotation in the 1-2 block is taken for the charged lepton masses. Motivated by the implications of the recent results on neutrino oscillations, $\\theta_{23}$ in the first octant and non-zero $\\theta_{13}$ are predicted by the ansatz. Three physical mixing angles are expressed in terms of a single variable, the 1-2 angle of charged leptons, so that a simple relation among the angles has been obtained: $\\tan\\theta_{13}=\\sqrt{2}(\\sin\\theta_{23}-\\sin\\theta_{12})$. It follows that a model of the inverted hierarchy that can produce the given ansatz is proposed.

Lightest Isotope of Bh Produced Via the 209Bi(52Cr,n)260BhReaction  

SciTech Connect (OSTI)

The lightest isotope of Bh known was produced in the new {sup 209}Bi({sup 52}Cr,n){sup 260}Bh reaction at the Lawrence Berkeley National Laboratory's 88-Inch Cyclotron. Positive identification was made by observation of eight correlated alpha particle decay chains in the focal plane detector of the Berkeley Gas-Filled Separator. {sup 260}Bh decays with a 35{sub -9}{sup +19} ms half-life by alpha particle emission mainly by a group at 10.16 MeV. The measured cross section of 59{sub -20}{sup +29} pb is approximately a factor of four larger than compared to recent model predictions. The influences of the N = 152 and Z = 108 shells on alpha decay properties are discussed.

Density-functional theory of macroscopic stress: Gradient-corrected calculations for crystalline Se  

Science Journals Connector (OSTI)

We generalize the Nielsen-Martin stress theorem beyond the local-density approximation (LDA) and present an alternative derivation of the whole theorem. We show that the exchange-correlation stress becomes anisotropic in the most general case: its explicit form is given within a gradient-corrected (GC) scheme. As a test implementation, we use the generalized theorem to achieve fast structural optimization in crystalline Se. In this material LDA predicts a rather poor structure period. Our GC calculation is in much better agreement with the experiment.

Low-temperature recrystallization of Ge nanolayers on ZnSe  

SciTech Connect (OSTI)

The in situ X-ray photoelectron spectroscopy observation of low-temperature recrystallization of an amorphous Ge layer deposited on a ZnSe film at room temperature is reported. It is shown that the experimentally measured shifts of the Ge 3d core level are consistent with the changes observed in the crystal structure of the layer by the high-energy electron diffraction technique in the reflection mode of measurements. The shifts can be attributed to successive nanometer-scaled structural changes in the Ge layer with increasing temperature.

SeZnSb alloy and its nano tubes, graphene composites properties  

SciTech Connect (OSTI)

Composite can alter the individual element physical property, could be useful to define the specific use of the material. Therefore, work demonstrates the synthesis of a new composition Se{sub 96}-Zn{sub 2}-Sb{sub 2} and its composites with 0.05% multi-walled carbon nano tubes and 0.05% bilayer graphene, in the glassy form. The diffused amorphous structure of the multi walled carbon nano tubes and bilayer gaphene in the Se{sub 96}-Zn{sub 2}-Sb{sub 2} alloy have been analyzed by using the Raman, X-ray photoluminescence spectroscopy, Furrier transmission infrared spectra, photoluminescence, UV/visible absorption spectroscopic measurements. The diffused prime Raman bands (G and D) have been appeared for the multi walled carbon nano tubes and graphene composites, while the X-ray photoluminescence core energy levels peak shifts have been observed for the composite materials. Subsequently the photoluminescence property at room temperature and a drastic enhancement (upto 80%) in infrared transmission percentage has been obtained for the bilayer graphene composite, along with optical energy band gaps for these materials have been evaluated 1.37, 1.39 and 1.41 eV.

Carrier multiplication yields in PbS and PbSe nanocrystals measured by transient photoluminescence  

Science Journals Connector (OSTI)

We report here an assessment of carrier multiplication (CM) yields in PbSe and PbS nanocrystals (NCs) by a quantitative analysis of biexciton and exciton dynamics in transient photoluminescence decays. Interest in CM, the generation of more than one electron and hole in a semiconductor after absorption of one photon, has renewed in recent years because of reports suggesting greatly increased efficiencies in nanocrystalline materials compared to the bulk form, in which CM was otherwise too weak to be of consequence in photovoltaic energy conversion devices. In our PbSe and PbS NC samples, however, we estimate using transient photoluminescence that at most 0.25 additional e-h pairs are generated per photon, even at photon energies five times larger than the first exciton energy, instead of the much higher values reported in the literature. We argue by comparing NC CM estimates and reported bulk values on an absolute energy basis, which we justify as appropriate on physical grounds, that the data reported thus far are inconclusive with respect to the importance of nanoscale-specific phenomena in the CM process.

First-principles investigation of the structural and vibrational properties of vitreous GeSe2  

Science Journals Connector (OSTI)

Using a density-functional scheme, we study the structural and vibrational properties of vitreous germanium diselenide (v-GeSe2). Through the use of classical and first-principles molecular-dynamics methods, we generate a set of structural models showing a varying degree of chemical disorder. In particular, two types of structural concepts are represented: one in which the tetrahedral order is preserved to a very large extent, and one which reproduces the high degree of disorder in first-neighbor shells found in first-principles molecular-dynamics simulations of the liquid. The investigated structural properties include the angular distributions, the atomic arrangements in the first-neighbor shells, and the pair-correlation functions. In reciprocal space, we have calculated the x-ray and neutron total structure factors and the partial structure factors. Comparison with experiment gives overall good agreement for the models of either structural conception. We then investigate the vibrational properties via the vibrational density of states and the inelastic neutron spectrum. The considered models yield similar spectra and agree with experimental data. We also obtain infrared and Raman spectra through a density-functional scheme based on the application of finite electric fields. For these spectra, significant differences appear among the models. The comparison with experiment favors a model showing a high degree of chemical order. The Raman intensity is analyzed in terms of the underlying atomic vibrations. The assignment of the Raman companion line to Se motions in edge-sharing tetrahedra is supported.
