P-type doping of GaN  

SciTech Connect (OSTI)

After implantation of As, As + Be, and As + Ga into GaN and annealing for short durations at temperatures as high as 1500 C, the GaN films remained highly resistive. It was apparent from c-RBS studies that although implantation damage did not create an amorphous layer in the GaN film, annealing at 1500 C did not provide enough energy to completely recover the radiation damage. Disorder recovered significantly after annealing at temperatures up to 1500 C, but not completely. From SIMS analysis, oxygen contamination in the AIN capping layer causes oxygen diffusion into the GaN film above 1400 C. The sapphire substrate (A1203) also decomposed and oxygen penetrated into the backside of the GaN layer above 1400 C. To prevent donor-like oxygen impurities from the capping layer and the substrate from contaminating the GaN film and compensating acceptors, post-implantation annealing should be done at temperatures below 1500 C. Oxygen in the cap could be reduced by growing the AIN cap on the GaN layer after the GaN growth run or by depositing the AIN layer in a ultra high vacuum (UHV) system post-growth to minimize residual oxygen and water contamination. With longer annealing times at 1400 C or at higher temperatures with a higher quality AIN, the implantation drainage may fully recover.

The Classification of M1-78  

E-Print Network [OSTI]

The published properties of M1-78 are discussed with the purpose to resolve the object's classification as either a planetary nebula or an ultracompact HII region. A classification as a planetary nebula is rejected primarily because of the high luminosity of the object, but because of the chemical composition and expansion velocity of the nebula, a novel classification is proposed instead: that of an ultracompact HII region with a post-main sequence central star (possibly a WN star). It must therefore follow that observable ultracompact HII regions persist beyond the main sequence lifetimes of at least some massive stars, and so cannot be transient phenomena that are seen only during pre-main sequence or early main sequence evolution.

Maskless lateral epitaxial overgrowth of GaN on sapphire  

SciTech Connect (OSTI)

The authors demonstrate a technique of lateral epitaxial overgrowth (LEO) of GaN, termed maskless LEO, in which no mask is deposited prior to LEO regrowth. Instead, a bulk (> 2 {micro}m) GaN layer on sapphire is selectively dry etched, leaving {approximately} 5 {micro}m-wide stripe mesas oriented in the <10{bar 1}0>{sub GaN} direction, with a 20 {micro}m period. These stripes serve as seeds for LEO GaN growth, which proceeds from the tops of the stripes and expands laterally, resulting in a T, or overhang, morphology. As for LEO over an SiO{sub 2} mask, significant defect reduction (from {approximately} 10{sup 9} cm{sup {minus}2} to {approximately} 10{sup 6} cm{sup {minus}2}) is observed in cross-sectional transmission electron microscopy (TEM). Atomic force microscopy of the top surface of the LEO GaN reveals that no threading dislocations with screw component terminate at the surfaces of laterally overgrown regions. X-ray diffraction measurements reveal that the wings exhibit a crystallographic tilt away from the seed regions in an azimuth perpendicular to the stripe direction; the tilt angle ({approximately} 0.4--0.5{degree}) is relatively independent of growth temperature and wing aspect ratio.

Si in GaN -- On the nature of the background donor  

SciTech Connect (OSTI)

A characterization of the Si impurity in GaN is performed by Raman spectroscopy. Applying hydrostatic pressure up to 25 GPa the authors study the behavior of the LO phonon-plasmon mode in a series of high mobility Si doped GaN films. In contrast to earlier results on unintentionally doped bulk GaN crystals no freeze out of the free carriers could be observed in Si doped samples. The authors find that Si is a shallow hydrogenic donor throughout the pressure range studied. This result positively excludes Si incorporation as a dominant source of free electrons in previously studied bulk GaN samples.

This paper reviews the various types of structural defects observed by Transmission Electron Microscopy in GaN heteroepitaxial layers grown on foreign substrates and homoepitaxial layers grown on bulk GaN substrates. The structural perfection of these layers is compared to the platelet self-standing crystals grown by High Nitrogen Pressure Solution. Defects in undoped and Mg doped GaN are discussed. Some models explaining the formation of inversion domains in heavily Mg doped layers that are possible defects responsible for the difficulties of p-doping in GaN are also reviewed.

Dynamic Model of Hydrogen in GaN  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Dynamic Model of Hydrogen in GaN by S. M. Myers and A. F. Wright Motivation-Hydrogen is incorporated into p-type GaN during MOCVD growth, producing highly stable passivation of the Mg acceptors. Complete acceptor activation by thermal H release requires temperatures that threaten material integrity, prompting compromises in device processing. At lower temperatures, forward bias of p-n junctions or electron-beam irradiation produces a metastable, reversible activation without H release. To understand and control such effects, we are developing a mathematical model of H behavior wherein state energies from density-functional theory are employed in diffusion-reaction equations. Previously, we used the greatly simplifying assumptions of local equilibrium among states

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.

Two-photon E1-M1 optical clock  

Science Journals Connector (OSTI)

An allowed E1-M1 excitation scheme creates optical access to the 1S0?3P0 clock transition in group-II-type atoms. This method does not require the hyperfine mixing or application of an external magnetic field of other optical clock systems. The advantages of this technique include a Doppler-free excitation scheme and increased portability with the use of vapor cells. We will discuss technical mechanisms of a monochromatic excitation scheme for a hot E1-M1 clock and briefly discuss a bichromatic scheme to eliminate light shifts. We determine the optimal experimental parameters for Hg, Yb, Ra, Sr, Ba, Ca, Mg, and Be and calculate that neutral Hg has ideal properties for a hot, portable frequency standard.

The E2/M1 ratio in {Delta} photoproduction  

SciTech Connect (OSTI)

The properties of the transition from the nucleon to the {Delta}(1232) serve as a benchmark for models of nucleon structure. To first order, N {r_arrow} {Delta} photo-excitation is dominated by a simple M1 quark spin-flip transition. At higher order, small L = 2 components in the N and {Delta} wavefunctions allow this excitation to proceed via an electric quadrupole transition. Since Nucleon models differ greatly on the mechanisms used to generate these L = 2 components,, the ratio of E2/M1 transitions (EMR) provides a sensitive test for structure models. Here, new high-precision measurements of p({rvec {gamma}}, {pi}) and p({rvec {gamma}}, {gamma}) cross sections and beam asymmetries have been combined with other polarization ratios in a simultaneous analysis of both reactions. Compton scattering has provided two important new constraints on the photo-pion amplitude. The E2/M1 mixing ratio for the N {r_arrow} {Delta} transition extracted from this analysis is EMR = {minus}3.0% {+-} 0.3 (stat+sys) {+-} 0.2 (model).

Optical resonance modes in GaN pyramid microcavities  

SciTech Connect (OSTI)

An array of GaN hexagonal pyramids with a side length of 8.0 {mu}m was fabricated by selective epitaxial overgrowth. These microsized pyramids are highly efficient microcavities. Three types of optical resonance modes with mode spacings of 10, 5.0, and 6.0 {Angstrom} were observed when a single pyramid was pumped optically by an intense ultraviolet laser beam. An optical ray tracing method has been developed for calculating the optical resonance modes inside the pyramid microcavities. It was shown that a single pyramidal cavity can support several different types of optical resonance modes. The calculated mode spacing agrees very well with the observations. The uniqueness and advantages of this class of hexagonal pyramidal microcavities over the other microcavities are discussed. The implications of our finding on the future GaN microcavity light emitters including micro-light-emitting diodes, microcavity lasers, and vertical-cavity-surface emitting lasers are also discussed. {copyright} {ital 1999 American Institute of Physics.}

In situ studies of the effect of silicon on GaN growth modes.  

SciTech Connect (OSTI)

We present real-time X-ray scattering studies of the influence of silicon on the homoepitaxial growth mode of GaN grown by metal-organic vapor-phase epitaxy. Both annealing of Si-doped GaN and surface dosing of GaN with disilane are shown to change the mode of subsequent growth from step-flow to layer-by-layer. By comparing the growth behavior induced by doped layers which have been annealed to that induced by surface dosing, we extract an approximate diffusion coefficient for Si in GaN of 3.5 x 10{sup -18} cm{sup 2}/s at 810{sup o}C.

Thermal annealing characteristics of Si and Mg-implanted GaN thin films  

SciTech Connect (OSTI)

In this letter, we report the results of ion implantation of GaN using {sup 28}Si and {sup 24}Mg species. Structural and electrical characterizations of the GaN thin films after thermal annealing show that native defects in the GaN films dominate over implant doping effects. The formation energies of the annealing induced defects are estimated to range from 1.4 to 3.6 eV. A 40 keV 10{sup 14} cm{sup {minus}2} Mg implant results in the decrease of the free-carrier concentration by three orders of magnitude compared to unimplanted GaN up to an annealing temperature of 690{degree}C. Furthermore, we have observed the correlation between these annealing-induced defects to both improved optical and electrical properties. {copyright} {ital 1996 American Institute of Physics.}

The effectiveness of stuttering treatments in Germany  

Science Journals Connector (OSTI)

AbstractPurpose Persons who stutter (PWS) should be referred to the most effective treatments available, locally or regionally. A prospective comparison of the effects of the most common stuttering treatments in Germany is not available. Therefore, a retrospective evaluation by clients of stuttering treatments was carried out. Method The five most common German stuttering treatments (231 single treatment cases) were rated as to their perceived effectiveness, using a structured questionnaire, by 88 PWS recruited through various sources. The participants had received between 1 and 7 treatments for stuttering. Results Two stuttering treatments (stuttering modification, fluency shaping) showed favorable and three treatments (breathing therapy, hypnosis, unspecified logopedic treatment) showed unsatisfactory effectiveness ratings. The effectiveness ratings of stuttering modification and fluency shaping did not differ significantly. The three other treatments were equally ineffective. The differences between the effective and ineffective treatments were of large effect sizes. The typical therapy biography begins in childhood with an unspecified logopedic treatment administered extensively in single and individual sessions. Available comparisons showed intensive or interval treatments to be superior to extensive treatments, and group treatments to be superior to single client treatments. Conclusion The stuttering treatment most often prescribed in Germany, namely a weekly session of individual treatment by a speech-language pathologist, usually with an assorted package of mostly unknown components, is of limited effectiveness. Better effectiveness can be expected from fluency shaping or stuttering modification approaches, preferably with an intensive time schedule and with group sessions. Educational objectives: Readers will be able to: (a) discuss the five most prevalent stuttering treatments in Germany; (b) summarize the effectiveness of these treatments; and (c) describe structural treatment components that seem to be preferable across different kinds of treatments.

Nanostructural engineering of nitride nucleation layers for GaN substrate dislocation reduction.  

SciTech Connect (OSTI)

With no lattice matched substrate available, sapphire continues as the substrate of choice for GaN growth, because of its reasonable cost and the extensive prior experience using it as a substrate for GaN. Surprisingly, the high dislocation density does not appear to limit UV and blue LED light intensity. However, dislocations may limit green LED light intensity and LED lifetime, especially as LEDs are pushed to higher current density for high end solid state lighting sources. To improve the performance for these higher current density LEDs, simple growth-enabled reductions in dislocation density would be highly prized. GaN nucleation layers (NLs) are not commonly thought of as an application of nano-structural engineering; yet, these layers evolve during the growth process to produce self-assembled, nanometer-scale structures. Continued growth on these nuclei ultimately leads to a fully coalesced film, and we show in this research program that their initial density is correlated to the GaN dislocation density. In this 18 month program, we developed MOCVD growth methods to reduce GaN dislocation densities on sapphire from 5 x 10{sup 8} cm{sup -2} using our standard delay recovery growth technique to 1 x 10{sup 8} cm{sup -2} using an ultra-low nucleation density technique. For this research, we firmly established a correlation between the GaN nucleation thickness, the resulting nucleation density after annealing, and dislocation density of full GaN films grown on these nucleation layers. We developed methods to reduce the nuclei density while still maintaining the ability to fully coalesce the GaN films. Ways were sought to improve the GaN nuclei orientation by improving the sapphire surface smoothness by annealing prior to the NL growth. Methods to eliminate the formation of additional nuclei once the majority of GaN nuclei were developed using a silicon nitride treatment prior to the deposition of the nucleation layer. Nucleation layer thickness was determined using optical reflectance and the nucleation density was determined using atomic force microscopy (AFM) and Nomarski microscopy. Dislocation density was measured using X-ray diffraction and AFM after coating the surface with silicon nitride to delineate all dislocation types. The program milestone of producing GaN films with dislocation densities of 1 x 10{sup 8} cm{sup -2} was met by silicon nitride treatment of annealed sapphire followed by the multiple deposition of a low density of GaN nuclei followed by high temperature GaN growth. Details of this growth process and the underlying science are presented in this final report along with problems encountered in this research and recommendations for future work.

Transport properties, specific heat and thermal conductivity of GaN nanocrystalline ceramic  

SciTech Connect (OSTI)

The structural and transport properties (resistivity, thermopower and Hall effect), specific heat and thermal conductivity have been measured for GaN nanocrystalline ceramic prepared by hot pressing. It was found that the temperature dependence of resistivity in temperature range 10-300 K shows the very low activation energy, which is ascribed to the shallow donor doping originating in amorphous phase of sample. The major charge carriers are electrons, what is indicated by negative sign of Hall constant and Seebeck coefficient. The thermopower attains large values (-58 {mu}V/K at 300 K) and was characterized by linear temperature dependence which suggests the diffusion as a major contribution to Seebeck effect. The high electron concentration of 1.3x10{sup 19} cm{sup -3} and high electronic specific heat coefficient determined to be 2.4 mJ/molK{sup 2} allow to conclude that GaN ceramic demonstrates the semimetallic-like behavior accompanied by very small mobility of electrons ({approx}0.1 cm{sup 2}/V s) which is responsible for its high resistivity. A low heat conductivity of GaN ceramics is associated with partial amorphous phase of GaN grains due to high pressure sintering. - Graphical Abstract: Thermal resistivity and thermopower measurements indicates the high phonon scattering and lack of phonon-drag contribution to thermopower in GaN nanoceramics pressed under 4 GPa at 800 {sup o}C.

Germany and America: Crisis of confidence  

SciTech Connect (OSTI)

The paper examines the deterioration in German-American relations. The reasons for this downturn in German-American relations are quite simple. Washington views the Persian Gulf crisis as a defining moment in European-American relations and in the creation of a new world order. It is also the first diplomatic test of a unified Germany and a new German-American relationship. It is a test that Germany is thus far seen as having failed for three reasons. First, from the outset many Americans sensed that Germans did not comprehend what this crisis meant for the United States. A second and, in many ways, more worrying factor was the growing sense that the Germans were not being good Europeans. The third and most serious American concern, however, was the unsettling appearance of a very selective German definition of collective defense and common security. The result has been a crisis of confidence in the performance of the German political elite that goes beyond the problems in German-American relations during the early 1980s and the INF debate.

Effect of buffer layer growth temperature on epitaxial GaN films deposited by magnetron sputtering  

SciTech Connect (OSTI)

Epitaxial GaN films were deposited by reactive sputtering of a GaAs target in 100 % nitrogen at 700 deg. C on ZnO buffer layers grown at different substrate temperatures over sapphire substrates. High resolution X-ray diffraction measurements and the corresponding analysis show that the growth temperature of buffer layers significantly affects the micro-structural parameters of GaN epilayer, such as lateral coherence length, tilt and twist, while the vertical coherence length remains unaffected. The optimum substrate temperature for buffer layer growth has been found to be 300 deg. C. High epitaxial quality GaN film grown on such a buffer layer exhibited micro strain of 1.8x10{sup -4} along with screw and edge type dislocation densities of 7.87x10{sup 9} and 1.16x10{sup 11}, respectively.

Green light emitting diode grown on thick strain-reduced GaN template  

Science Journals Connector (OSTI)

Abstract We report a green light-emitting diode (LED) grown on thick strain-reduced GaN template. As the injection current changes from 20 mA to 120 mA, blue-shift of EL peak wavelength reduces from 9.3 nm for the LED on sapphire substrate to 6.8 nm for the LED grown on thick strain-reduced GaN template. Furthermore, the light output power and external quantum efficiency of the LED on thick strain-reduced GaN template are respectively 1.48 mW and 2.5% at the forward current of 20 mA, which is twice as much as the LED on sapphire substrate. In contrast, the reverse current is 2 ?A lower than that of the LED on the sapphire at ?8 V.

Physical Properties of GaN Nanotubes as Revealed by Computer Simulation  

SciTech Connect (OSTI)

Single-crystalline wurtzite GaN nanotubes have been synthesized recently with proposed applications in nanoscale electronics, optoelectronics and the biochemical-sensing field. Molecular dynamics methods with a Stillinger-Weber potential are used to investigate the melting behavior, thermal conductivity and mechanical properties of these wurtzite-type single crystalline GaN nanotubes. Four major topical areas are summarized in this chapter. (1) The melting temperature of the GaN nanotubes increases with the thickness of the nanotubes to a saturation value, which is close to the melting temperature of bulk GaN. The simulations result reveal that the nanotubes begin to melt at the surface, and then the melting rapidly extends to the interior of the nanotubes as the temperature increases. (2) The thermal conductivity of nanotubes is smaller than that of the bulk GaN single crystal. The thermal conductivity is also found to decrease with temperature and increase with increasing wall thickness of the nanotubes. The change of phonon spectrum and surface inelastic scattering may account for the reduction of thermal conductivity in the nanotubes, while thermal softening and high frequency phonon interactions at high temperatures may provide an explanation for its decrease with increasing temperature. (3) At low temperatures, the simulation results show that the nanotubes exhibit brittle properties; whereas at high temperatures, they behave as ductile materials. The brittle to ductile transition temperature generally increases with increasing wall thickness of the nanotubes and increasing strain rate. (4) The simulation temperature, tube length and strain rate affect the buckling behavior of GaN nanotubes. The critical stress decreases with the increase of simulation temperature and tube length. The dependence of buckling on tube length is consistent with the analysis of equivalent continuum structures using Euler buckling theory.

Lattice dynamics of GaN: Effects of 3d electrons  

Science Journals Connector (OSTI)

We perform first-principles calculations of structural, dielectric, and lattice-dynamical properties of cubic GaN. The equilibrium structure is obtained using the plane-wave pseudopotential approach within the density-functional theory and local-density approximation. The dielectric and vibrational properties are computed within the density-functional perturbation theory. The effect of the Ga 3d electrons is treated by taking into account the nonlinear core corrections for the exchange and correlation energy. The importance of 3d electrons for the bonding strength is determined, and their influence on the dielectric and dynamical properties of GaN is analyzed and discussed.

Partially filled intermediate band of Cr-doped GaN films  

SciTech Connect (OSTI)

We investigated the band structure of sputtered Cr-doped GaN (GaCrN) films using optical absorption, photoelectron yield spectroscopy, and charge transport measurements. It was found that an additional energy band is formed in the intrinsic band gap of GaN upon Cr doping, and that charge carriers in the material move in the inserted band. Prototype solar cells showed enhanced short circuit current and open circuit voltage in the n-GaN/GaCrN/p-GaN structure compared to the GaCrN/p-GaN structure, which validates the proposed concept of an intermediate-band solar cell.

Nucleation and Growth of GaN on GaAs (001) Substrates  

SciTech Connect (OSTI)

The nucleation of GaN thin films on GaAs is investigated for growth at 620 "C. An rf plasma cell is used to generate chemically active nitrogen from N2. An arsenic flux is used in the first eight monolayer of nitride growth to enhance nucleation of the cubic phase. Subsequent growth does not require an As flux to preserve the cubic phase. The nucleation of smooth interfaces and GaN films with low stacking fault densities is dependent upon relative concentrations of active nitrogen species in the plasma and on the nitrogen to gallium flux ratio.

Selective etching of dislocations in GaN grown by low-pressure solution growth  

Science Journals Connector (OSTI)

This work presents an experimental study on the identification and quantification of different types of dislocations in GaN grown by low-pressure solution growth. A reliable defect selective etching procedure in a NaOH-KOH melt is developed and validated using transmission electron microscopy that permits to define groups of etch pits that belong each to dislocations with a specific Burgers vector. This way a comparably fast method is provided for determining the total, the specific dislocation densities and the type of dislocation in a statistically representative way. The results for the solution grown samples are compared to those obtained for MOCVD GaN.

Ge doped GaN with controllable high carrier concentration for plasmonic applications  

SciTech Connect (OSTI)

Controllable Ge doping in GaN is demonstrated for carrier concentrations of up to 2.4?×?10{sup 20} cm{sup ?3}. Low temperature luminescence spectra from the highly doped samples reveal band gap renormalization and band filling (Burstein-Moss shift) in addition to a sharp transition. Infrared ellipsometry spectra demonstrate the existence of electron plasma with an energy around 3500?cm{sup ?1} and a surface plasma with an energy around 2000?cm{sup ?1}. These findings open possibilities for the application of highly doped GaN for plasmonic devices.

M1 Giant Resonance in Pb208 From Threshold Photoneutron Measurements  

Science Journals Connector (OSTI)

From threshold photoneutron cross-section and angular-distribution measurements on Pb208, seven 1+ states have been detected, which have a total M1 strength of 51 eV. This M1 strength, centered at an excitation energy of 7.9 MeV and spread over a range of 700 keV, constitutes at least half and perhaps all of the total M1 strength obtained from shell-model calculations.

High Efficiency m-plane LEDs on Low Defect Density Bulk GaN Substrates  

SciTech Connect (OSTI)

Solid-state lighting is a key technology for reduction of energy consumption in the US and worldwide. In principle, by replacing standard incandescent bulbs and other light sources with sources based on light-emitting diodes (LEDs), ultimate energy efficiency can be achieved. The efficiency of LEDs has improved tremendously over the past two decades, however further progress is required for solid- state lighting to reach its full potential. The ability of an LED at converting electricity to light is quantified by its internal quantum efficiency (IQE). The material of choice for visible LEDs is Gallium Nitride (GaN), which is at the basis of blue-emitting LEDs. A key factor limiting the performance of GaN LEDs is the so-called efficiency droop, whereby the IQE of the LED decreases significantly at high current density. Despite decades of research, efficiency droop remains a major issue. Since high-current operation is necessary for practical lighting applications, reducing droop is a major challenge for the scientific community and the LED industry. Our approach to solving the droop issue is the use of newly available low-defect-density bulk GaN non-polar substrates. In contrast to the standard foreign substrates (sapphire, silicon carbide, silicon) used in the industry, we have employed native bulk GaN substrates with very low defect density, thus ensuring exquisite material quality and high IQE. Whereas all commercial LEDs are grown along the c-plane crystal direction of GaN, we have used m-plane non-polar substrates; these drastically modify the physical properties of the LED and enable a reduction of droop. With this approach, we have demonstrated very high IQE performance and low droop. Our results focused on violet and blue LEDs. For these, we have demonstrated very high peak IQEs and current droops of 6% and 10% respectively (up to a high current density of 200A.cm-2). All these results were obtained under electrical operation. These high IQE and low droop values are in line with the program’s milestones. They demonstrate that bulk non-polar GaN substrates represent a disruptive technology for LED performance. Application of this technology to real-world products is feasible, provided that the cost of GaN substrates is compatible with the market’s requirement.

Ab initio density functional theory study of non-polar (101{sup ¯}0),?(112{sup ¯}0) and semipolar (202{sup ¯}1) GaN surfaces  

SciTech Connect (OSTI)

The atomic structures of non-polar GaN(101{sup ¯}0),?(112{sup ¯}0) and semipolar GaN(202{sup ¯}1),?(202{sup ¯}1{sup ¯}) surfaces were studied using ab initio calculations within density functional theory. The bulk-like truncated (1?×?1) structure with buckled Ga-N or Ga-Ga dimers was found stable on the non-polar GaN(101{sup ¯}0) surface in agreement with previous works. Ga-N heterodimers were found energetically stable on the GaN(112{sup ¯}0)-(1?×?1) surface. The formation of vacancies and substitution site defects was found unfavorable for non-polar GaN surfaces. Semipolar GaN(202{sup ¯}1)-(1?×?1) surface unit cells consist of non-polar (101{sup ¯}0) and semipolar (101{sup ¯}1) nano-facets. The (101{sup ¯}1) nano-facets consist of two-fold coordinated atoms, which form N-N dimers within a (2?×?1) surface unit cell on a GaN(202{sup ¯}1) surface. Dimers are not formed on the GaN(202{sup ¯}1{sup ¯}) surface. The stability of the surfaces with single (101{sup ¯}0) or (101{sup ¯}1) nano-facets was analyzed. A single non-polar (101{sup ¯}0)-(1?×?1) nano-facet was found stable on the GaN(202{sup ¯}1) surface, but unstable on the GaN(202{sup ¯}1{sup ¯}) surface. A single (101{sup ¯}1) nano-facet was found unstable. Semipolar GaN surfaces with (202{sup ¯}1) and (202{sup ¯}1{sup ¯}) polarity can be stabilized with a Ga overlayer at Ga-rich experimental conditions.

Substrate-dependent wetting layer formation during GaN growth: Impact on the morphology of the films  

SciTech Connect (OSTI)

We have compared epitaxial growth of GaN films on 6H-SiC(0001)-({radical}(3)x{radical}(3))R30 deg. -Ga and on (0001)-sapphire. Predeposited Ga layers were nitrided by ion beam assisted molecular beam epitaxy. Whereas on SiC the initially deposited Ga covers the substrate surface completely, on sapphire only Ga droplets are present. The different distribution of the predeposited Ga affects the morphology of GaN significantly. Scanning electron microscopy and atomic force microscopy analysis of the grown films show that the complete wetting of the SiC substrate with Ga enhances finally the size and the flatness of GaN terraces and thus the quality of the film. X-ray photoelectron spectroscopy measurements reveal that metallic Ga resides also on top of the GaN films during the growth.

Ultra-low resistance ohmic contacts to GaN with high Si doping concentrations grown by molecular beam epitaxy  

SciTech Connect (OSTI)

Ti/Al/Ni/Au ohmic contacts were formed on heavily doped n{sup +} metal-polar GaN samples with various Si doping concentrations grown by molecular beam epitaxy. The contact resistivity (R{sub C}) and sheet resistance (R{sub sh}) as a function of corresponding GaN free carrier concentration (n) were measured. Very low R{sub C} values (<0.09 {Omega} mm) were obtained, with a minimum R{sub C} of 0.035 {Omega} mm on a sample with a room temperature carrier concentration of {approx}5 Multiplication-Sign 10{sup 19} cm{sup -3}. Based on the systematic study, the role of R{sub C} and R{sub sh} is discussed in the context of regrown n{sup +} GaN ohmic contacts for GaN based high electron mobility transistors.

Influence of growth temperature and temperature ramps on deep level defect incorporation in m-plane GaN  

SciTech Connect (OSTI)

The dependence of deep level defect incorporation in m-plane GaN films grown by metal-organic chemical vapor deposition on bulk m-plane GaN substrates as a function of growth temperature (T{sub g}) and T{sub g} ramping method was investigated using deep level optical spectroscopy. Understanding the influence of T{sub g} on GaN deep level incorporation is important for InGaN/GaN multi-quantum well (MQW) light emitting diodes (LEDs) and laser diodes (LDs) because GaN quantum barrier (QB) layers are grown much colder than thin film GaN to accommodate InGaN QW growth. Deep level spectra of low T{sub g} (800?°C) GaN films grown under QB conditions were compared to deep level spectra of high T{sub g} (1150?°C) GaN. Reducing T{sub g}, increased the defect density significantly (>50×) through introduction of emergent deep level defects at 2.09?eV and 2.9?eV below the conduction band minimum. However, optimizing growth conditions during the temperature ramp when transitioning from high to low T{sub g} substantially reduced the density of these emergent deep levels by approximately 40%. The results suggest that it is important to consider the potential for non-radiative recombination in QBs of LED or LD active regions, and tailoring the transition from high T{sub g} GaN growth to active layer growth can mitigate such non-radiative channels.

Growth and characterizations of GaN micro-rods on graphene films for flexible light emitting diodes  

SciTech Connect (OSTI)

We report the growth of GaN micro-rods and coaxial quantum-well heterostructures on graphene films, together with structural and optical characterization, for applications in flexible optical devices. Graphene films were grown on Cu foil by means of chemical vapor deposition, and used as the substrates for the growth of the GaN micro-rods, which were subsequently transferred onto SiO{sub 2}/Si substrates. Highly Si-doped, n-type GaN micro-rods were grown on the graphene films using metal–organic chemical vapor deposition. The growth and vertical alignment of the GaN micro-rods, which is a critical factor for the fabrication of high-performance light-emitting diodes (LEDs), were characterized using electron microscopy and X-ray diffraction. The GaN micro-rods exhibited promising photoluminescence characteristics for optoelectronic device applications, including room-temperature stimulated emission. To fabricate flexible LEDs, In{sub x}Ga{sub 1–x}N/GaN multiple quantum wells and a p-type GaN layer were deposited coaxially on the GaN micro-rods, and transferred onto Ag-coated polymer substrates using lift-off. Ti/Au and Ni/Au metal layers were formed to provide electrical contacts to the n-type and p-type GaN regions, respectively. The micro-rod LEDs exhibited intense emission of visible light, even after transfer onto the flexible polymer substrate, and reliable operation was achieved following numerous cycles of mechanical deformation.

We discuss systematics of the {ital M}1 scissors mode within the interacting boson model when the {ital g}-boson degree of freedom is included explicitly and microscopically motivated choices of model parameters are adopted. We try to relate the {ital M}1 centroid energy to the energetics of deformation. We conclude that, with the introduction of a hexadecapole-hexadecapole interaction and a {ital g}-boson admixture in the ground state of only a few percent, we can obtain reasonable estimates of the {ital M}1 centroid energy, without invoking a Majorana interaction. If one takes seriously variations in microscopic estimates of boson {ital g} factors, then the summed {ital M}1 strength near midshell can be interpreted in terms of boson occupation numbers which saturate. {copyright} {ital 1996 The American Physical Society.}

Design and Simulation of Novel Enhancement Mode 5–20 kV GaN Vertical Superjunction High Electron Mobility Transistors for Smart Grid Applications  

Science Journals Connector (OSTI)

We report on the design, simulations and optimization of a novel enhancement mode 5–20 kV GaN vertical superjunction (SJ) high electron mobility transistor (HEMT). We optimize the space charge in GaN pillars using GaN SJ p–n diode for the best trade-off between breakdown voltage (BV) and specific on-resistance (Ronsp), by varying the pillar dosage, length and width. The resulting GaN SJ field effect transistor (FET) structure is projected to have, for example, Ronsp of 4.2 m? cm2 with BV of 12.4 kV.

Identification of the gallium vacancy-oxygen pair defect in GaN  

SciTech Connect (OSTI)

Cation vacancies like V{sub Ga}, V{sub Al} and their complexes with oxygen are predicted to be abundant in III-nitrides and to play an important role in nonradiative recombination. Appearing in triple or double negatively charged states, they are not paramagnetic and have not so far been detected by magnetic resonance even under illumination. In this Brief Report, we demonstrate an efficient way to make cation vacancy defects in GaN detectable by electron paramagnetic resonance and present our identification of the V{sub Ga}O{sub N} pair in GaN which is the model material for the III-nitrides and their alloys.

Subpicosecond time-resolved Raman studies of nonequilibrium excitations in wurtzite GaN  

SciTech Connect (OSTI)

Non-equilibrium electron distributions as well as phonon dynamics in wurtzite GaN have been measured by subpicosecond time-resolved Raman spectroscopy. The experimental results have demonstrated that for electron densities n {ge} 5 {times} 10{sup 17} cm{sup {minus}3}, the non-equilibrium electron distributions in wurtzite GaN can be very well described by Fermi-Dirac distribution functions with the temperature of electrons substantially higher than that of the lattice. The population relaxation time of longitudinal optical phonons was directly measured to be {tau} {approx_equal} 5 {+-} 1 ps at T = 25 K. The experimental results on the temperature dependence of the lifetime of longitudinal optical phonons suggest that the primary decay channels for these phonons are the decay into (1) one transverse optical phonon and one high energy, longitudinal or transverse acoustical phonons; and (2) one transverse optical phonon and one E{sub 2} phonon.

Charge transfer in Fe-doped GaN: The role of the donor  

SciTech Connect (OSTI)

Several nitride-based device structures would benefit from the availability of high quality, large-area, freestanding semi-insulating GaN substrates. Due to the intrinsic n-type nature of GaN, however, the incorporation of compensating centers such as Fe is necessary to achieve the high resistivity required. We are using electron paramagnetic resonance (EPR) to explore charge transfer in 450 um thick GaN:Fe plates to understand the basic mechanisms related to compensation so that the material may be optimized for device applications. The results suggest that the simple model based on one shallow donor and a single Fe level is insufficient to describe compensation. Rather, the observation of the neutral donor and Fe3+ indicates that either the two species are spatially segregated or additional compensating and donor defects must be present.

Theoretical and experimental study of dynamics of photoexcited carriers in GaN  

SciTech Connect (OSTI)

We present a theoretical and experimental study of the sub-picosecond dynamics of photo-excited carriers in GaN. In the theoretical model, interaction with an external ultrafast laser pulse is treated coherently and to account for the scattering mechanisms and dephasing processes, a generalized Monte-Carlo simulation is used. The scattering mechanisms included are carrier interactions with polar optical phonons and acoustic phonons, and carrier-carrier Coulomb interactions. We study the effect of different scattering mechanisms on the carrier densities. In the case that the excitation energy satisfies the threshold for polar optical scattering, phonon contribution is the dominant process in relaxing the system, otherwise, carrier-carrier mechanism is dominant. Furthermore, we present the temperature and pulse power dependent normalized luminescence intensity. The results are presented over a range of temperatures, electric field, and excitation energy of the laser pulse. For comparison, we also report the experimental time-resolved photoluminescence studies on GaN samples. There is a good agreement between the simulation and experiment in normalized luminescence intensity results. Therefore, we show that we can explain the dynamics of the photo-excited carriers in GaN by including only carrier-carrier and carrier-phonon interactions and a relatively simple two-band electronic structure model.

Anisotropy of effective electron masses in highly doped nonpolar GaN  

SciTech Connect (OSTI)

The anisotropic effective electron masses in wurtzite GaN are determined by generalized infrared spectroscopic ellipsometry. Nonpolar (112{sup ¯}0) oriented thin films allow accessing both effective masses, m{sub ?}{sup *} and m{sub ?}{sup *}, by determining the screened plasma frequencies. A n-type doping range up to 1.7?×?10{sup 20}?cm{sup ?3} is investigated. The effective mass ratio m{sub ?}{sup *}/m{sub ?}{sup *} is obtained with highest accuracy and is found to be 1.11 independent on electron concentration up to 1.2?×?10{sup 20}?cm{sup ?3}. For higher electron concentrations, the conduction band non-parabolicity is mirrored in changes. Absolute values for effective electron masses depend on additional input of carrier concentrations determined by Hall effect measurements. We obtain m{sub ?}{sup *}=(0.239±0.004)m{sub 0} and m{sub ?}{sup *}=(0.216±0.003)m{sub 0} for the parabolic range of the GaN conduction band. Our data are indication of a parabolic GaN conduction band up to an energy of approximately 400?meV above the conduction band minimum.

Red light emitting solid state hybrid quantum dot–near-UV GaN LED devices  

Science Journals Connector (OSTI)

We produced core–shell (CdSe)ZnSe quantum dots by direct colloidal chemical synthesis and the surface-passivation method—an overcoating of the core CdSe with a larger-bandgap material ZnSe. The (CdSe)ZnSe quantum dots(QDs) play the role of a colour conversion centre. We call these quantum dots nanophosphors. We fabricated red light emitting hybrid devices of (CdSe)ZnSe QDs and a near-UV GaN LED by combining red light emitting (CdSe)ZnSe quantum dots (as a colour conversion centre) with a near-UV(NUV) GaN LED chip (as an excitation source). A few good red phosphors have been known for UV excitation wavelengths, and red phosphors for UV excitation have been sought for a long time. Here we tested the possibility of using (CdSe)ZnSe QDs as red nanophosphors for UV excitation. The fabricated red light emitting hybrid device of (CdSe)ZnSe and a NUV GaN LED chip showed a good luminance. We demonstrated that the (CdSe)ZnSe quantum dots were promising red nanophosphors for NUV excitation and that a red LED made of QDs and a NUV excitation source was a highly efficient hybrid device.

A survey of environmental needs and innovative technologies in Germany  

SciTech Connect (OSTI)

The International Technology Program (IT?), formerly the international Technology Exchange Program (ITEP), of the Department of Energy`s (DOE`s) Office of Environmental Restoration and Waste Management (EM) is responsible for promoting: (1) the import of innovative technologies to better address EM`s needs; and (2) the export of US services into foreign markets to enhance US competitiveness. Under this program: (1) the environmental restoration market in Germany was evaluated, including the description of the general types of environmental problems, the environmental regulations, and specific selected contaminated sites; and (2) potentially innovative environmental restoration technologies, either commercially available or under development in Germany, were identified, described and evaluated. It was found that: (1) the environmental restoration market in Germany is very large, on the order of several billion US dollars per year, with a significant portion possibly available to US businesses; and (2) a large number (54) of innovative environmental restoration technologies, which are either commercially available or under development in Germany, may have some benefit to the DOE EM program and should be considered for transfer to the US.

Scanning tunneling microscopy on unpinned GaN(11¯00) surfaces: Invisibility of valence-band states  

Science Journals Connector (OSTI)

We investigated the origins of the tunnel current in scanning tunneling microscopy (STM) and spectroscopy experiments on GaN(11¯00) surfaces. By calculating the tunnel currents in the presence of a tip-induced band bending for unpinned n-type GaN(11¯00) surfaces, we demonstrate that only conduction-band states are observed at positive and negative voltage polarities independent of the doping concentration. Valence-band states remain undetectable because tunneling out of the electron-accumulation zone in conduction-band states dominates by four orders of magnitude. As a result band-gap sizes cannot be determined by STM on unpinned GaN(11¯00) surfaces. Appropriate band-edge positions and gap sizes can be determined on pinned surfaces.

Ab initio study on noncompensated CrO codoping of GaN for enhanced solar energy conversion  

SciTech Connect (OSTI)

We describe a novel photocatalyst obtained by codoping GaN with CrO, according to a new "noncompensated" codoping concept based on first-principles calculations. The approach enables controllable narrowing of the GaN band gap with significantly enhanced carrier mobility and photocatalytic activity in the visible light region and thus offers immense potential for application in solar energy conversion, water splitting, and a variety of solar-assisted photocatalysis. Our calculations indicate that the formation energy for the cation doping is greatly reduced by noncompensated codoping with an anion. Although Cr doping alone can split the band gap with the formation of an intermediate band, the mobility is low due to carrier trapping by the localized states. The first-principles calculations also demonstrate that CrO codoping of GaN shifts the Fermi level into the conduction band resulting in high carrier density and mobility.

SciTech Connect (OSTI)

This paper presents a summary of work accomplished within the scope of the DOE-Gosatomnadzor (GAN) Agreement to reduce vulnerability to theft of direct-use nuclear materials in Russia. The DOE-GAN agreement concerns the Russian Academy of Science B.P. Konstantinov Petersburg Nuclear Physics Institute (PNPI), located 45 kilometers from St. Petersburg. The PNPI operates facilities to research basic nuclear physics. Current world conditions require particular attention to the issue of Material Protection, Control, and Accounting (MPC&A) of nuclear materials. The long-term plan to increase security at the facility is outlined, including training, physical protection upgrades, and material control and accountability. 4 figs.

The impact of nanoperforation on persistent photoconductivity and optical quenching effects in suspended GaN nanomembranes  

SciTech Connect (OSTI)

We report on fabrication of suspended ?15?nm thick GaN membranes nanoperforated in an ordered fashion using direct writing of negative charges by focused ion beam and subsequent photoelectrochemical etching of GaN epilayers. Both continuous and nanoperforated membranes exhibit persistent photoconductivity (PPC), which can be optically quenched under excitation by 546?nm radiation. Optical quenching of PPC occurs also under relatively intense intrinsic excitation of nanoperforated membranes by 355?nm radiation at T?

Nanoscale size dependence parameters on lattice thermal conductivity of Wurtzite GaN nanowires  

SciTech Connect (OSTI)

Graphical abstract: Temperature dependence of calculated lattice thermal conductivity of Wurtzite GaN nanowires. Highlights: Black-Right-Pointing-Pointer A modified Callaway model is used to calculate lattice thermal conductivity of Wurtzite GaN nanowires. Black-Right-Pointing-Pointer A direct method is used to calculate phonon group velocity for these nanowires. Black-Right-Pointing-Pointer 3-Gruneisen parameter, surface roughness, and dislocations are successfully investigated. Black-Right-Pointing-Pointer Dislocation densities are decreases with the decrease of wires diameter. -- Abstract: A detailed calculation of lattice thermal conductivity of freestanding Wurtzite GaN nanowires with diameter ranging from 97 to 160 nm in the temperature range 2-300 K, was performed using a modified Callaway model. Both longitudinal and transverse modes are taken into account explicitly in the model. A method is used to calculate the Debye and phonon group velocities for different nanowire diameters from their related melting points. Effect of Gruneisen parameter, surface roughness, and dislocations as structure dependent parameters are successfully used to correlate the calculated values of lattice thermal conductivity to that of the experimentally measured curves. It was observed that Gruneisen parameter will decrease with decreasing nanowire diameters. Scattering of phonons is assumed to be by nanowire boundaries, imperfections, dislocations, electrons, and other phonons via both normal and Umklapp processes. Phonon confinement and size effects as well as the role of dislocation in limiting thermal conductivity are investigated. At high temperatures and for dislocation densities greater than 10{sup 14} m{sup -2} the lattice thermal conductivity would be limited by dislocation density, but for dislocation densities less than 10{sup 14} m{sup -2}, lattice thermal conductivity would be independent of that.

Science Journals Connector (OSTI)

Using conventional time to pulse-height techniques, the lifetimes of the low-lying levels in La137 and Kr83 have been measured, despite the low ?-ray energies (10 and 9.3 keV) and the large internal conversion coefficients (130 and 11). The results of 89±4 and 147±4 nsec, respectively, correspond to retardation factors of 370 and 45 over the single-particle model predictions for those M1 transitions.

Doping and isolation of GaN, InGaN and InAlN using ion implantation  

SciTech Connect (OSTI)

Both n- and p-type doping have been achieved in GaN using Si{sup +} or Mg{sup +}/P{sup +} implantation, respectively, followed annealing at {ge} 1050{degrees}C. Using proximity rapid thermal annealing (10sec) the GaN surface retains both smooth morphology and its original stoichiometry. Variable temperature Hall measurements reveal approximate energy levels of 62meV for the implanted Si and 171meV for the Mg, which are similar to their values in epitaxially grown GaN. Implant isolation of both n- and p-type GaN, and n-type In{sub 0.75}Al{sub 0.25}N with multiple energy inert species (e.g. N{sup +} or F{sup +}) produces high resistivity ({ge}10{sup 8}{omega}/{open_square}) after subsequent annealing in the range 600-700{degrees}C. Smaller increases in sheet resistance are observed for In{sub x}Ga{sup 1-x}N (x=0.33-0.75) under the same conditions due to the smaller energy bandgaps and the shallower energy levels of the damage-related states controlling the resistivity.

First-principles calculations of the structural and electronic properties of clean GaN(0001) surfaces  

Science Journals Connector (OSTI)

We employ density-functional theory (DFT) within the local-density approximation (LDA) and generalized-gradient approximation (GGA) to study structural and electronic properties of clean GaN(0001) surfaces. The pseudopotential method is used to investigate surfaces with (1×1), (2×2), and (3×3)R30° reconstructions. We also report calculations for the N2 molecule and for the bulk phases of Ga and GaN. We find that GGA give better results than LDA for the cohesive energies, but not for the structural properties. Bulk band structures are found to be very similar for both exchange-correlation potentials. Examining the clean GaN(0001) surfaces we conclude that both potentials give very similar relaxations and an almost identical dispersion for the surface states. We also report results for ionization energies, electron affinities, and work function for the GaN(0001) surfaces. As a general trend the ionization energy decreases monotonically with the increasing of the Ga-coverage.

Is Germany?s energy transition a case of successful green industrial policy? Contrasting wind and solar PV  

Science Journals Connector (OSTI)

Abstract In this paper, we address the challenge of Germany?s energy transition (Energiewende) as the centrepiece of the country?s green industrial policy. In addition to contributing to global climate change objectives, the Energiewende is intended to create a leading position for German industry in renewable energy technologies, boost innovative capabilities and create employment opportunities in future growth markets at the least possible cost. The success in reaching these aims, and indeed the future of the entire concept, is hotly debated. The paper aims to provide an up-to-date assessment of what has become a fierce controversy by comparing solar photovoltaic (PV) and wind energy along five policy objectives: (1) competitiveness, (2) innovation, (3) job creation, (4) climate change mitigation, and (5) cost. We find mixed evidence that Germany reaches its green industrial policy aims at reasonable costs. Wind energy seems to perform better against all policy objectives, while the solar PV sector has come under intense pressure from international competition. However, this is only a snapshot of current performance, and the long term and systemic perspective required for the energy sector transformation suggests a need for a balanced mix of a variety of clean energy sources.

Annealing of the radiation damage in Mg-implanted GaN thin films: Temperature development of lattice parameters and stresses  

Science Journals Connector (OSTI)

Heteroepitaxial GaN thin films implanted with Mg ions with a concentration of 1.3 × 1019 cm?3 are analyzed using in-situ X-ray diffraction in the temperature range of 20–700 °C. The temperature dependence of unstressed lattice parameters and stresses in the implanted films is evaluated and compared with the results from a virgin GaN thin film. The measurements indicate that the annealing of the radiation damage in the implanted GaN is accompanied by a unique temperature hysteresis of the GaN structural characteristics and the main part of the radiation damage is removed during heating in the temperature range of 100–300 °C. The temperature of 1620 °C is extrapolated as an important annealing limit in order to significantly decrease implantation-induced disorder in the films.

Challenges dealing with depleted uranium in Germany - Reuse or disposal  

SciTech Connect (OSTI)

During enrichment large amounts of depleted Uranium are produced. In Germany every year 2.800 tons of depleted uranium are generated. In Germany depleted uranium is not classified as radioactive waste but a resource for further enrichment. Therefore since 1996 depleted Uranium is sent to ROSATOM in Russia. However it still has to be dealt with the second generation of depleted Uranium. To evaluate the alternative actions in case a solution has to be found in Germany, several studies have been initiated by the Federal Ministry of the Environment. The work that has been carried out evaluated various possibilities to deal with depleted uranium. The international studies on this field and the situation in Germany have been analyzed. In case no further enrichment is planned the depleted uranium has to be stored. In the enrichment process UF{sub 6} is generated. It is an international consensus that for storage it should be converted to U{sub 3}O{sub 8}. The necessary technique is well established. If the depleted Uranium would have to be characterized as radioactive waste, a final disposal would become necessary. For the planned Konrad repository - a repository for non heat generating radioactive waste - the amount of Uranium is limited by the licensing authority. The existing license would not allow the final disposal of large amounts of depleted Uranium in the Konrad repository. The potential effect on the safety case has not been roughly analyzed. As a result it may be necessary to think about alternatives. Several possibilities for the use of depleted uranium in the industry have been identified. Studies indicate that the properties of Uranium would make it useful in some industrial fields. Nevertheless many practical and legal questions are open. One further option may be the use as shielding e.g. in casks for transport or disposal. Possible techniques for using depleted Uranium as shielding are the use of the metallic Uranium as well as the inclusion in concrete. Another possibility could be the use of depleted uranium for the blending of High enriched Uranium (HEU) or with Plutonium to MOX-elements. (authors)

Investigations of chemical vapor deposition of GaN using synchrotron radiation  

SciTech Connect (OSTI)

The authors apply synchrotron x-ray analysis techniques to probe the surface structure of GaN films during synthesis by metal-organic chemical vapor deposition (MOCVD). Their approach is to observe the evolution of surface structure and morphology in real time using grazing incidence x-ray scattering (GIXS). This technique combines the ability of x-rays to penetrate the chemical vapor deposition environment for in situ measurements, with the sensitivity of GIXS to atomic scale structure. In this paper they present examples from some of their studies of growth modes and surface evolution as a function of process conditions that illustrate the capabilities of synchrotron x-ray analysis during MOCVD growth. They focus on studies of the homoepitaxial growth mode, island coarsening dynamics, and effects of impurities.

Structural Properties of Eu-Doped GaN Investigated by Raman Spectroscopy  

SciTech Connect (OSTI)

Rare-earth (RE) impurities doped GaN are highly promising candidates for light emitting device applications due to their efficient electroluminescence properties at room temperature. Among those, Eu doped GaN has been identified as an excellent material for the red spectral region due to its strong emission at 620 nm. As a transition internal to the Eu doping atom (4f-4f), light emission originates in a much smaller complex than the more flexibly controllable quantum structures of wells, wires, and dots. This is thought to make the center less susceptible to structural defects and in particular radiation damage in the lattice host. Nevertheless, the lattice host is crucial for providing the excitation in from of free electrons and holes. In this respect, the actual lattice site Eu occupies in the host lattice, i.e. in GaN, is important. A large fraction of Eu atoms are typically inactive which must be attributed to their lattice site and local environment. GaN films implanted with Eu to concentrations of {approx}10{sup 18} cm{sup -3} were subjected to a highly directed beam of 500 keV He{sup +} at a dose of 5 x 10{sup 14} cm{sup -2}. By means of a shadow mask, irradiated and unexposed regions lie very close to each other on the same sample. We used optical and structural analysis to identify the exerted radiation damage. At the full radiation dose, photoluminescence intensity has decayed to {approx}0.01 of its initial value. From the dose dependence of the radiation decay we previously concluded, that this decay is in part due to the destruction of radiative Eu sites [J.W. Tringe, unpublished (2006)]. Along the transition from virgin to irradiated material we analyze the accumulated damage in terms of surface morphology (atomic force microscopy), crystallinity (x-ray diffraction), and phonon dispersion using micro-Raman spectroscopy. In addition to the well-studied E{sub 2}(high) mode, two new vibrational modes at 659 cm{sup -1} and 201 cm{sup -1} were observed in the Eu implanted and annealed sample, prior to He{sup +} irradiation. These modes are either remnants of the implantation damage or related to the Eu impurity. As such they can be indicative of the actual lattice site the Eu atom resides on. After irradiation, broad Raman modes at 300 cm-1 are being observed. This band indicates disorder activated Raman scattering (DARS) due to the radiation damage. An additional narrow mode appears at 672 cm{sup -1}, which can possibly be due to a nitrogen vacancy related vibrational mode. The continuous transition from irradiated to un-irradiated sample allows the direct evolution of radiation damage and its coordinated effects in structural, optical and vibrational properties. By its systematic correlation we anticipate to be able to elucidate the Eu lattice interaction and the processes of radiation damage.

First observation of the M1 transition $?(3686)\\to ??_c(2S)$  

E-Print Network [OSTI]

Using a sample of 106 million \\psi(3686) events collected with the BESIII detector at the BEPCII storage ring, we have made the first measurement of the M1 transition between the radially excited charmonium S-wave spin-triplet and the radially excited S-wave spin-singlet states: \\psi(3686)\\to\\gamma\\eta_c(2S). Analyses of the processes \\psi(2S)\\to \\gamma\\eta_c(2S) with \\eta_c(2S)\\to \\K_S^0 K\\pi and K^+K^-\\pi^0 gave an \\eta_c(2S) signal with a statistical significance of greater than 10 standard deviations under a wide range of assumptions about the signal and background properties. The data are used to obtain measurements of the \\eta_c(2S) mass (M(\\eta_c(2S))=3637.6\\pm 2.9_\\mathrm{stat}\\pm 1.6_\\mathrm{sys} MeV/c^2), width (\\Gamma(\\eta_c(2S))=16.9\\pm 6.4_\\mathrm{stat}\\pm 4.8_\\mathrm{sys} MeV), and the product branching fraction (\\BR(\\psi(3686)\\to \\gamma\\eta_c(2S))\\times \\BR(\\eta_c(2S)\\to K\\bar K\\pi) = (1.30\\pm 0.20_\\mathrm{stat}\\pm 0.30_\\mathrm{sys})\\times 10^{-5}). Combining our result with a BaBar measurement of \\BR(\\eta_c(2S)\\to K\\bar K \\pi), we find the branching fraction of the M1 transition to be \\BR(\\psi(3686)\\to\\gamma\\eta_c(2S)) = (6.8\\pm 1.1_\\mathrm{stat}\\pm 4.5_\\mathrm{sys})\\times 10^{-4}.

Fiftieth CCR reformer goes on stream in Germany  

SciTech Connect (OSTI)

The fiftieth continuous catalytic reformer built since this technology was introduced by UOP Process Division in 1971 has gone on stream in West Germany. The 21,300-b/sd unit is in Deutsche Shell AG's Godorf refinery. It is the sixth such unit put in service by Shell International. Others are in refineries at Harburg, West Germany; Shellhaven, England; Palau Bokum, Singapore; Pernis, Netherlands; and Geelong, Australia. CCR units operate at much higher severity than older reforming units. Severity is a function of higher octane, lower pressure, and feedstock. The operating severity or catalyst deactivation rate may be 20 times that of high pressure, low octane units. Continuous catalyst regeneration is then the key for maintaining long-term operations at steady state conditions. To facilitate continuous catalyst regeneration, the three reactors are stacked. This design permits the catalyst to move in essentially plug flow through the reactors at a rate determined by the rate of catalyst withdrawal to the regeneration section.

Efficient Switches for Solar Power Conversion: Four Quadrant GaN Switch Enabled Three Phase Grid-Tied Microinverters  

SciTech Connect (OSTI)

Solar ADEPT Project: Transphorm is developing power switches for new types of inverters that improve the efficiency and reliability of converting energy from solar panels into useable electricity for the grid. Transistors act as fast switches and control the electrical energy that flows in an electrical circuit. Turning a transistor off opens the circuit and stops the flow of electrical current; turning it on closes the circuit and allows electrical current to flow. In this way a transistor can be used to convert DC from a solar panel into AC for use in a home. Transphorm’s transistors will enable a single semiconductor device to switch electrical currents at high-voltage in both directions—making the inverter more compact and reliable. Transphorm is using Gallium Nitride (GaN) as a semiconductor material in its transistors instead of silicon, which is used in most conventional transistors, because GaN transistors have lower losses at higher voltages and switching frequencies.

An attempt has been made to measure the internal conversion coefficients of the M1+E2 radiations of Au199 and Au195 with sufficient accuracy to check the effect of the finite nuclear size on internal conversion in this region of Z. In the case of Au199 a direct comparison of the 158-kev pure E2 transition with the 208-kev M1+E2 radiation was possible. Comparison of the gamma-ray intensities determined from scintillation spectrometry with conversion line intensities measured in a small shaped-field spectrometer yielded K, L, M, total shell coefficients. Comparison of these gamma-ray intensities with conversion line intensities photographically recorded in a higher resolution permanent-field spectrometer led to L-subshell coefficients. The results for the 208-kev transition are: aK=0.71±0.05, aL=0.144±0.01, aLI=0.114±0.007, aLII=0.0227±0.0007, aLIII=0.0065±0.0005, aM=0.042±0.04, and aN+O=0.0083±0.001. The empirical multiplicative factors f by which point-nucleus theoretical values are to be reduced, presumably due to the finite nuclear effect, and the E2 mixing ratio r have been determined: fK=0.762±0.08, fLI=0.78±0.13, fLII=1.00±0.06, fLIII=1.0, and r=0.11±0.03. These results, insofar as they may be compared, are not inconsistent with Sliv's predictions (fK=0.8). An experimental value of 0.60 was found for the screening correction to Rose's M-shell coefficients for this Z and energy region.In the case of Au195 only permanent-field spectrograph measurements of the L- and M-subshell conversion of the 98-kev M1+E2 transition were accurate enough for analysis. A comparison of the experimental ratios with the corresponding theoretical point-nucleus L and M values, the latter being corrected empirically for screening, gives: fLI=0.82±0.10, fLII=0.73±0.20, r=0.014±0.003. In this analysis it has been assumed that LIII shell correction is negligible.More accurate energy values and branching ratios have been obtained. For the radiations of Au199 we find energies of 49.7, 158.3, and 208.0 kev with corresponding relative intensities 8%, 76%, and 16%. The Au195 energies and relative transition rates are 30.8, 98.5, and 129.4 kev, 20%, 72%, and 8%, respectively. Energy values are internally consistent to 0.10 kev.

Photoluminescence from GaN layers at high temperatures as a candidate for in situ monitoring in MOVPE  

Science Journals Connector (OSTI)

Abstract Efficient photoluminescence (PL) spectra from GaN and InGaN layers at temperatures up to 1100 K are observed with low noise floor and high dynamic resolution. A number of detailed spectral features in the PL can be directly linked to physical properties of the epitaxial grown layer. The method is suggested as an in situ monitoring tool during epitaxy of nitride LED and laser structures. Layer properties like thickness, band gap or film temperature distribution are feasible.

Study of gain and photoresponse characteristics for back-illuminated separate absorption and multiplication GaN avalanche photodiodes  

SciTech Connect (OSTI)

The gain and photoresponse characteristics have been numerically studied for back-illuminated separate absorption and multiplication (SAM) GaN avalanche photodiodes (APDs). The parameters of fundamental models are calibrated by simultaneously comparing the simulated dark and light current characteristics with the experimental results. Effects of environmental temperatures and device dimensions on gain characteristics have been investigated, and a method to achieve the optimum thickness of charge layer is obtained. The dependence of gain characteristics and breakdown voltage on the doping concentration of the charge layer is also studied in detail to get the optimal charge layer. The bias-dependent spectral responsivity and quantum efficiency are then presented to study the photoresponse mechanisms inside SAM GaN APDs. It is found the responsivity peak red-shifts at first due to the Franz-Keldysh effect and then blue-shifts due to the reach-through effect of the absorption layer. Finally, a new SAM GaN/AlGaN heterojunction APD structure is proposed for optimizing SAM GaN APDs.

Determination of gamma from Charmless B --> M1 M2 Decays Using U-Spin  

E-Print Network [OSTI]

In our previous paper we applied U-spin symmetry to charmless hadronic B+- --> M0 M+- decays for the purpose of precise extraction of the unitarity angle gamma. In this paper we extend our approach to neutral B0 and Bs --> M1 M2 decays. A very important feature of this method is that no assumptions regarding relative sizes of topological decay amplitudes need to be made. As a result, this method avoids an uncontrollable theoretical uncertainty that is often related to the neglect of some topological diagrams (e.g., exchange and annihilation graphs) in quark-diagrammatic approaches. In charged B+- decays, each of the four data sets, P0 P+-, P0 V+-, V0 P+- and V0 V+-, with P=pseudoscalar and V=vector, can be used to obtain a value of gamma. Among neutral decays, only experimental data in the B0, Bs --> P- P+ subsector is sufficient for a U-spin fit. Application of the U-spin approach to the current charged and neutral B decay data yields: gamma=(80^{+6}_{-8}) degrees. In this method, which is completely data dr...

Proposals in for Czech firms; cooperation likely with eastern Germany  

SciTech Connect (OSTI)

Two Western groups - Shell and a consortium made up of Agip, Conoco, and Total - have offered to buy the refining operations of Chemopetrol Litvinov and Kaucuk Kralupy, both in the Czech republic. Meanwhile, Amoco, Neste, and PCD are looking at the possibility of acquiring some of the plastics plants at Litvinov. Amoco is interested in the polypropylene operations, Neste in polyethylene, and PCD in both. The two Czech firms are included in the second wave of privatization, which will begin in midyear. So far, there have been no offers for the 80,000-m.t./year polystyrene and 60,000-m.t./year styrene butadiene rubber operations belonging to Kralupy, although Atochem representatives recently visited the plants. Litvinov is carrying out revamping operations at its core unit, a 12-year-old, 450,000-m.t./year ethylene plant. The plant, currently running at 400,000 m.t./year, supplies downstream plants, Neratovice, and sells on the export markets. An existing ethylene pipeline between Litvinov and Bohlen in eastern Germany, which used to supply an average 100,000 m.t./year of ethylene to Bohen in exchange for naphtha, is virtually unused. One proposal involves reactivating this exchange to secure ethylene feedstock for plants in eastern Germany. According to some sources, a preliminary decision has been made to shut down the 100,000-m.t./year ethylene plant at Leuna and possibly to expand the Bohlen cracker by 100,000 m.t./year, to 400,000 m.t./year by the late 1990s.

Characterization of GaN nanowires grown on PSi, PZnO and PGaN on Si (111) substrates by thermal evaporation  

SciTech Connect (OSTI)

In this research, we used an easy and inexpensive method to synthesize highly crystalline GaN nanowires (NWs); on different substrates such as porous silicon (PSi), porous zinc oxide (PZnO) and porous gallium nitride (PGaN) on Si (111) wafer by thermal evaporation using commercial GaN powder without any catalyst. Micro structural studies by scanning electron microscopy and transmission electron microscope measurements reveal the role of different substrates in the morphology, nucleation and alignment of the GaN nanowires. The degree of alignment of the synthesized nanowires does not depend on the lattice mismatch between wires and their substrates. Further structural and optical characterizations were performed using high resolution X-ray diffraction and energy-dispersive X-ray spectroscopy. Results indicate that the nanowires are of single-crystal hexagonal GaN. The quality and density of grown GaN nanowires for different substrates are highly dependent on the lattice mismatch between the nanowires and their substrates and also on the size of the porosity of the substrates. Nanowires grown on PGaN have the best quality and highest density as compared to nanowires on other substrates. By using three kinds of porous substrates, we are able to study the increase in the alignment and density of the nanowires.

Temperature dependence of photoconductivity in Zn-doped GaN  

SciTech Connect (OSTI)

In agreement with predictions from a model that explained an abrupt thermal quenching of the blue luminescence (BL) band in high-resistivity Zn-doped GaN [Reshchikov et al., Phys. Rev. B 84, 075212 (2011) and Phys. Rev. B 85, 245203 (2012)], we observed the stepwise decrease of photoconductivity in this material with increasing temperature. For the sample studied in this work, the decrease in photoconductivity occurred in two steps at characteristic temperatures T{sub 1} and T{sub 2}. The characteristic temperatures increased with increasing excitation intensity, very similar to the photoluminescence (PL) behavior. The steps in photoconductivity at about 100 K and 200 K are attributed to drop in the concentration of free electrons due to the thermal emission of holes from a shallow acceptor and the Zn{sub Ga} acceptor, respectively, to the valence band and their recombination with electrons via nonradiative centers. This finding supports the model suggested previously and helps to explain other examples of tunable photoconductivity reported in literature.

Polarity determination for MOCVD growth of GaN on Si(111) by convergent beam electron diffraction[Metal Organic Chemical Vapor Deposition  

SciTech Connect (OSTI)

The polarity of laterally epitaxially overgrown (LEO) GaN on Si(111) with an AlN buffer layer grown by MOCVD has been studied by convergent beam electron diffraction (CBED). The LEO GaN was studied by cross-section and plan-view transmission electron microscopy (TEM). The threading dislocation density is less than 10{sup 8} cm{sup {minus}2} and no inversion domains were observed. CBED patterns were obtained at 200 kV for the <1 {bar 1} 00> zone. Simulation was done by many-beam solution with 33 zero-order beams. The comparison of experimental CBED patterns and simulated patterns indicates that the polarity of GaN on Si(111) is Ga face.

An overview of solar photovoltaic energy in Mexico and Germany  

Science Journals Connector (OSTI)

Abstract Energy is essential for our preservation and the improvement of our life-style. Today all major production of energy is generated from fossil fuels, which are non-renewable and significantly pollute the environment. Access to clean and reliable energy is crucial for assuring the development of countries such as Mexico. Mexico's economy is based on producing energy from fossil fuels11 91% of Mexico's energy is produced from non-renewable energy sources. Moreover, 36% of primarily renewable energy corresponds to the use of firewood for cooking used in a non-healthy and non-sustainable way [42]. GTZ is the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) GmbH (German Technical Cooperation, German Federal Ministry for Economic Cooperation and Development). and the change to sustainable ways of life is still uncertain. It becomes essential to look at developed countries where the transition to sustainability has been rapidly increasing. This paper gives an overview of energy policies and the potential of solar photovoltaic energy in two countries: Germany, a world leader in the generation and development of photovoltaic technology; and Mexico, a country with great solar photovoltaic potential. It also describes the characteristics, advantages and disadvantages of photovoltaic technology, including BIPV systems.

Large low-energy $M1$ strength for $^{56,57}$Fe within the nuclear shell model  

E-Print Network [OSTI]

A strong enhancement at low $\\gamma$-ray energies has recently been discovered in the $\\gamma$-ray strength function of $^{56,57}$Fe. In this work, we have for the first time obtained theoretical $\\gamma$ decay spectra for states up to $\\approx 8$ MeV in excitation for $^{56,57}$Fe. We find large $B(M1)$ values for low $\\gamma$-ray energies that provide an explanation for the experimental observations. The role of mixed $E2$ transitions for the low-energy enhancement is addressed theoretically for the first time, and it is found that they contribute a rather small fraction. Our calculations clearly show that the high-$\\ell$ ($=f$) diagonal terms are most important for the strong low-energy $M1$ transitions. As such types of $0\\hbar\\omega$ transitions are expected for all nuclei, our results indicate that a low-energy $M1$ enhancement should be present throughout the nuclear chart. This could have far-reaching consequences for our understanding of the $M1$ strength function at high excitation energies, with profound implications for astrophysical reaction rates.

Highly mismatched crystalline and amorphous GaN(1-x)As(x) alloys in the whole composition range  

SciTech Connect (OSTI)

Alloying is a commonly accepted method to tailor properties of semiconductor materials for specific applications. Only a limited number of semiconductor alloys can be easily synthesized in the full composition range. Such alloys are, in general, formed of component elements that are well matched in terms of ionicity, atom size, and electronegativity. In contrast there is a broad class of potential semiconductor alloys formed of component materials with distinctly different properties. In most instances these mismatched alloys are immiscible under standard growth conditions. Here we report on the properties of GaN1-xAsx, a highly mismatched, immiscible alloy system that was successfully synthesized in the whole composition range using a nonequilibrium low temperature molecular beam epitaxy technique. The alloys are amorphous in the composition range of 0.17GaN to ~;;0.8 eV at x~;;0.85. The reduction in the band gap can be attributed primarily to the downward movement of the conduction band for alloys with x>0.2, and to the upward movement of the valence band for alloys with x<0.2. The unique features of the band structure offer an opportunity of using GaN1-xAsx alloys for various types of solar power conversion devices.

GaN nanorod light emitting diodes with suspended graphene transparent electrodes grown by rapid chemical vapor deposition  

SciTech Connect (OSTI)

Ordered and dense GaN light emitting nanorods are studied with polycrystalline graphene grown by rapid chemical vapor deposition as suspended transparent electrodes. As the substitute of indium tin oxide, the graphene avoids complex processing to fill up the gaps between nanorods and subsequent surface flattening and offers high conductivity to improve the carrier injection. The as-fabricated devices have 32% improvement in light output power compared to conventional planar GaN-graphene diodes. The suspended graphene remains electrically stable up to 300?°C in air. The graphene can be obtained at low cost and high efficiency, indicating its high potential in future applications.

The E2/M1 mixing ratio in the excitation of the {Delta} from polarized photo-reactions  

SciTech Connect (OSTI)

In constituent quark models, a tensor interaction, mixing quark spins with their relative motion, is introduced to reproduce the observed baryon spectrum. This has a consequence completely analogous to the nuclear tensor force between the n and p in deuterium. A D state component is mixed into what would otherwise be a purely S-wave object. The D-wave component breaks spherical symmetry, resulting in a non-vanishing matrix element for the nucleon and a static quadrupole moment and deformation for its first excited state, the {Delta} resonance, at {approximately}325 MeV. The magnitude and sign of this D-state component are quite sensitive to the internal structure of the proton and have been of great interest in recent years. The intrinsic deformation of the spin 1/2 nucleon cannot be observed directly; it must be inferred from transition amplitudes such as N {yields} {Delta}. In a spherical bag model, the {Delta} is viewed as a pure quark-spin-flip transition proceeding only through M1 excitation. If there are D-state admixtures in the ground state of the nucleon and/or {Delta}, quadrupole excitation, in addition to spin-flip M1, is also allowed. The problem is to evaluate the relative magnitude of this E2 excitation in the presence of the dominant M1 transition. A variety of models predict this mixing ratio to be quite small, anywhere from {minus}0.9% to {minus}6%, so that a high degree of precision is demanded of experiment.

Why Are Residential PV Prices in Germany So Much Lower Than in the United

Why Are Residential PV Prices in Germany So Much Lower Than in the United Why Are Residential PV Prices in Germany So Much Lower Than in the United States? Speaker(s): Joachim Seel Date: April 11, 2013 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Ryan Wiser The installed price of residential PV is significantly lower in Germany than in the United States - in Q3 2012 German systems were priced on average at $2.50/W while U.S. systems were priced nearly twice as high around $5.20/W. These pricing differences accumulate to about $13,500 for a 5kW residential system and stem primarily from differences in "soft" costs, but little detail is known about how soft cost components differ between the two countries, or why. In order to better characterize the nature of these differences, LBNL fielded surveys of German PV installers,

Large area supersonic jet epitaxy of AlN, GaN, and SiC on silicon  

SciTech Connect (OSTI)

AlN, GaN, and SiC thin films were grown on 100 mm diameter Si(111) and Si(100) substrates using Supersonic Jet Epitaxy (SJE). Precursor gases were seeded in lighter mass carrier gases and free jets were formed using novel slit-jet apertures. The jet design, combined with substrate rotation, allowed for a uniform flux distribution over a large area of a 100 mm wafer at growth pressures of 1--20 mTorr. Triethylaluminum, triethylgallium, and ammonia were used for nitride growth, while disilane, acetylene, and methylsilane were used for SiC growth. The films were characterized by in situ optical reflectivity, x-ray diffraction (XRD), atomic force microscopy (AFM), and spectroscopic ellipsometry (SE).

The electricity supply industry in Germany: market power or power of the market?  

Science Journals Connector (OSTI)

This paper analyses the electricity supply industry in Germany, which was liberalized in April 1998. Noticeable aspects are the eligibility of all end-users, the lack of constraints on the vertical industry structure and the option for negotiated third party access. There is no sector-specific regulation. This paper argues that the vertically integrated firms concentrate on excessive network access charges, whereas the stages generation and retail appear to be relatively competitive. Empirical evidence suggests that in Germany network access charges make up a significantly higher share of end-user prices than in the UK, which is used as regulation-benchmark.

Establishing interconnection to the grid is a recognized barrier to the deployment of distributed energy generation. This report compares interconnection processes for photovoltaic projects in California and Germany. This report summarizes the steps of the interconnection process for developers and utilities, the average length of time utilities take to process applications, and paperwork required of project developers. Based on a review of the available literature, this report finds that while the interconnection procedures and timelines are similar in California and Germany, differences in the legal and regulatory frameworks are substantial.

On the influence of solution density on the formation of macroscopic defects in the liquid phase epitaxy of GaN  

Science Journals Connector (OSTI)

This paper reports on a new simple method for avoiding particle-induced macroscopic defects using the liquid phase epitaxy (LPE) of GaN as an example. In a series of growth experiments by LPE of GaN it is demonstrated that the number of particle-induced macrodefects in the epitaxial layers correlates strongly and reproducibly with the density of the solution. In solutions with a density higher than that of the deleterious particles, the particles float on the solution and hence are hindered to get into contact with the seed, which is placed at the bottom of the crucible. Consequently, so-called depressions — a typical particle-induced defect in GaN–LPE layers — are avoided. The principle of avoiding the formation of macroscopic defects originating from particles by adapting the density of the solution (density criterion) should be generally applicable to solution growth processes, regardless of the material system.

Confirmation of intrinsic electron gap states at nonpolar GaN(1-100) surfaces combining photoelectron and surface optical spectroscopy  

SciTech Connect (OSTI)

The electronic structure of GaN(1–100) surfaces is investigated in-situ by photoelectron spectroscopy (PES) and reflection anisotropy spectroscopy (RAS). Occupied surface states 3.1?eV below the Fermi energy are observed by PES, accompanied by surface optical transitions found in RAS around 3.3?eV, i.e., below the bulk band gap. These results indicate that the GaN(1–100) surface band gap is smaller than the bulk one due to the existence of intra-gap states, in agreement with density functional theory calculations. Furthermore, the experiments demonstrate that RAS can be applied for optical surface studies of anisotropic crystals.

This thesis analyzes German perspectives on the international security environment and offers judgments about the probable future role of nuclear deterrence in European security. The thesis begins with a survey of the role of nuclear deterrence in the security policy of the Federal Republic of Germany during the period prior to reunification in 1989-1990. This is followed by an analysis of German views on the West European nuclear powers: the United Kingdom and France. German views on the U.S. nuclear presence and U.S. commitments to Europe are then examined. German views on nuclear weapons in the former Soviet Union and the potential for proliferation on Europe's periphery complete the survey. For the short term, Germany will not change its present policies regarding nuclear deterrence in Europe. The German nation is likely to remain preoccupied with the re-unification process for several years, and German politicians are not disposed to seek a debate on nuclear deterrence. The Germans generally consider Britain and France incapable of providing adequate nuclear protection for the Federal Republic in the near term. so the Germans will continue to rely on the United States for a nuclear guarantee.

Sputtering of Si, SiC, InAs, InP, Ge, GaAs, GaSb, and GaN by electrosprayed nanodroplets  

SciTech Connect (OSTI)

This article presents a characterization of the damage caused by energetic beams of electrosprayed nanodroplets striking the surfaces of single-crystal semiconductors including Si, SiC, InAs, InP, Ge, GaAs, GaSb, and GaN. The sputtering yield (number of atoms ejected per projectile's molecule), sputtering rate, and surface roughness are measured as functions of the beam acceleration potential. The maximum values of the sputtering yields range between 1.9 and 2.2 for the technological important but difficult to etch SiC and GaN respectively, and 4.5 for Ge. The maximum sputtering rates for the non-optimized beam flux conditions used in our experiments vary between 409?nm/min for SiC and 2381?nm/min for GaSb. The maximum sputtering rate for GaN is 630?nm/min. Surface roughness increases modestly with acceleration voltage, staying within 2?nm and 20?nm for all beamlet acceleration potentials and materials except Si. At intermediate acceleration potentials, the surface of Si is formed by craters orders of magnitude larger than the projectiles, yielding surface roughness in excess of 60?nm. The effect of projectile dose is studied in the case of Si. This parameter is correlated with the formation of the large craters typical of Si, which suggests that the accumulation of damage following consecutive impacts plays an important role in the interaction between beamlet and target.

SciTech Connect (OSTI)

The hydrothermal Mo-V-based mixed oxide catalysts possessing the M1-phase structure were investigated by XANES and in situ X-ray diffraction under ambient and dynamic redox conditions in the presence of O{sub 2} and H{sub 2} at 693 K. Under ambient conditions, XANES, with the use of model compounds, suggested oxidation states of Nb, Te, Mo, and V close to 5+, 4+, 6+, and 4+, respectively, in the bulk M1 phase. The oxidation state changes of Nb, Te, and Mo were not detected under the dynamic redox conditions employed, while the pre-edge peak of vanadium in the M1 phase exhibited small, reproducible shifts, suggesting that VO{sub x} is the active catalytic species in the bulk M1-phase catalysts for selective (amm)oxidation of propane.

Potential of the Power-to-Heat Technology in District Heating Grids in Germany  

Science Journals Connector (OSTI)

Abstract The increasing amount of power generation from weather-dependent renewable sources in Germany is projected to lead to a considerable number of hours in which power generation exceeds power demand. One possibility to take advantage of this power surplus is through the Power-to-Heat technology. As combined heat and power (CHP)-plants can be upgraded relatively easily with a Power-to-Heat facility, a huge potential can be developed in German district heating grids which are mainly served by CHP-plants. In this paper the potential of the Power-to-Heat technology in district heating grids in Germany is evaluated for the years 2015 to 2030 under different assumptions.

Effects of defect clustering on optical properties of GaN by single and molecular ion irradiation  

SciTech Connect (OSTI)

The effects of irradiation by F, P, and PF{sub 4} on optical properties of GaN were studied experimentally and by atomistic simulations. Additionally, the effect of Ag was studied by simulation. The irradiation energy was 0.6?keV/amu for all projectiles. The measured photoluminescence (PL) decay time was found to be decreasing faster when irradiation was done by molecular ion compared to light ion irradiation. The PL decay time change is connected with the types of defect produced by different projectiles. Simulation results show that the light ions mainly produce isolated point defects while molecular and heavy ions produce clusters of point defects. The total amount of defects produced by the PF{sub 4} projectile was found to be very close to the sum of all defects produced in five individual cascades started by one P and four F single ions. This and the similar depth profiles of damage produced by molecular and light ion irradiations suggest that the defect clusters are one of the important reasons for fast PL decay. Moreover, the simulations of irradiation by Ag ions, whose mass is close to the mass of the PF{sub 4} molecule, showed that the produced defects are clustering in even bigger conglomerates compared to PF{sub 4} case. The latter has a tendency to split in the pre-surface region, reducing on average the density of the collision cascade.

Neutron-transmuted carbon-14 in neutron-irradiated GaN: Compensation of DX-like center  

SciTech Connect (OSTI)

The transmuted-C related luminescence and net carrier concentration are studied by combining photoluminescence, liquid scintillation, and Raman scattering. GaN single crystal films grown by metalorganic-vapor-phase epitaxy are irradiated with fast and thermal neutrons at fluxes of 3.9 × 10{sup 13} cm{sup ?2}s{sup ?1} and 8.15 × 10{sup 13} cm{sup ?2}s{sup ?1}, respectively. Irradiation time is 48 hours. The calculated {sup 72}Ge and {sup 14}C concentrations are 1.24 × 10{sup 18} cm{sup ?3} and 1.13 × 10{sup 18} cm{sup ?3}, respectively. The transmuted {sup 14}C is detected by the liquid scintillation method to survey ?-rays emitted in the process of {sup 14}C decays from {sup 14}N. Tritium ({sup 3}H) is also emitted by a (n,t) reaction of {sup 14}N due to the neutron irradiation above 4.5 MeV. Photoluminescence relating to C, DX-like center of Ge and yellow luminescence band are observed in 1000 °C annealed NTD-GaN. The free electron concentration estimated from Raman scattering is 4.97 × 10{sup 17} cm{sup ?3}. This value is lower than that from the transmuted Ge concentration, suggesting the compensation due to the transmuted {sup 14}C acceptors.

A comparative analysis of the development of renewable energy in Brazil and Germany  

Science Journals Connector (OSTI)

This paper aims at reviewing the applied strategies to stimulate the development of and investments in renewable energies in Germany and Brazil. It analyses governmental programs and provides an overview about the past, present, and future development of wind, solar, and hydro energy in both countries. By collecting and comparing different preconditions, structures and the overall development, the paper reveals pitfalls of strategies and mechanisms applied in both countries. Results indicate that while the structure and stage of development of economies in Brazil and Germany differ, both countries share the intention to change the configuration of electricity generation. On the one hand, Germany applies a range of costly incentive mechanisms increasing the share of renewable energy fundamentally. On the other hand, Brazil already has a significant share of renewable energy, but yet established a strategy that may lead to an increased share of fossil energy. Based on the comparison, the paper deduces hints to foster the development of sustainable energy generation in both countries.

Economic viability in thermal retrofit policies: Learning from ten years of experience in Germany  

Science Journals Connector (OSTI)

Germany aims to reduce CO2 emissions by 80% by 2050 compared to 1990 levels and has merged this target with mandatory Energy Saving Regulations for thermal renovation of existing homes: the policy uses the criterion of ‘economic viability’, whereby renovations must pay back through the space and water heating fuel savings they produce. This paper explores the extent to which economically viable thermal renovations can contribute to the 80% goal, based on an analysis of Germany’s experience. It finds that the theoretical savings being achieved, based on calculated pre- and post-renovation consumption, are around 33%, while actual savings, based on measured consumption, are likely to be around 25%. The difference appears to be due to the effects of household behaviour. Further, average measured consumption is estimated to be around 150–180 kWh/m2a nationally, and this would have to be reduced to 30–35 kWh/m2a to meet the 80% policy goal. This is beyond the limits of economically viable renovation technology, which currently achieves around 100 kWh/m2a. The paper suggests that policymakers should de-couple the criterion of economic viability from the 80% goal, emphasise other reasons for renovating to economically viable levels, and consider a more systematic approach to facilitate household behaviour change.

Review of green electricity products in the United Kingdom, Germany and Finland  

Science Journals Connector (OSTI)

Abstract In liberalized electricity markets, environmental aspects are often used in marketing in addition to price competition and a wide variety of green electricity products marketed as environmentally friendly is available for customers. We study these green electricity markets in the UK, Germany and Finland and discuss possible problems between voluntary markets and renewable energy policies in particular. We find that products are claimed to support new renewable capacity building and to offer other environmental benefits through different kinds of mechanisms. Demand is relative high in Germany but has remained modest in the UK. In Finland, many passive private customers have automatically been sold green electricity products. Price premiums depend on several factors but typically they are in the range of 0–5%. The interface between voluntary markets and renewable energy policies can create problems; in the UK there are concerns that some suppliers double count renewable energy so that they assign the already required renewable energy to green tariff customers. We found that the share of imported hydropower is very large in green electricity products in Germany, which is why real additional benefits can be small. In Finland green electricity usually originates from hydro and wind power. As hydropower capacity is large in the Nordic countries, the additional impacts on new capacity can remain modest. For consumers, being a shareholder in companies devoted only to building new capacity, and products where price premiums are transparently directed to specific funds, carry the least risk of buying green products with false expectations.

A stochastic programming approach for optimal microgrid economic operation under uncertainty using 2m?+?1 point estimate method  

Science Journals Connector (OSTI)

By increasing concern over climate change and the security of energy supplies wind power and photovoltaic are emerging as important sources of electrical energy throughout the world. The wind speed at a given location is continuously varying. There are changes in the annual mean wind speed from year to year (annual) changes with season (seasonal) with passing weather systems (synoptic) on a daily basis (diurnal) and from second to second (turbulence). Common sense tells us that irradiation varies regionally with the changing seasons and hourly with the daily variation of the sun's evaluation. This paper proposes a new method for optimal management of MicroGrids under uncertain environments. In this study the 2m?+?1 point estimate method is used to model the uncertainty in the load demands the market prices and the electric power generation of the wind farms and the photovoltaic systems. The Weibull Beta and normal distributions are used to handle the uncertain input variables in this study. Moreover a Self-Adaptive Bee Swarm Optimization algorithm is presented to achieve an optimal-operational planning with regard to the cost minimization. In the proposed framework four different moving patterns are suggested in order to make an adaptive and robust optimization algorithm for different problems with different fitness landscape. In the devised method each bee self-adaptively chooses one of the proposed moving patterns according to a probability model to update its position. The proposed probability model is based on the ability of each strategy to generate more optimal solutions in the past generations. The efficiency of the method is validated on a typical microgrid.

CHROMOSPHERIC EVAPORATION IN AN M1.8 FLARE OBSERVED BY THE EXTREME-ULTRAVIOLET IMAGING SPECTROMETER ON HINODE  

SciTech Connect (OSTI)

We discuss observations of chromospheric evaporation for a complex flare that occurred on 2012 March 9 near 03:30 UT obtained from the Extreme-ultraviolet Imaging Spectrometer (EIS) on board the Hinode spacecraft. This was a multiple event with a strong energy input that reached the M1.8 class when observed by EIS. EIS was in raster mode and fortunately the slit was almost at the exact location of a significant energy input. Also, EIS obtained a full-CCD spectrum of the flare, i.e., the entire CCD was readout so that data were obtained for about the 500 lines identified in the EIS wavelength ranges. Chromospheric evaporation characterized by 150-200 km s{sup -1} upflows was observed in multiple locations in multi-million degree spectral lines of flare ions such as Fe XXII, Fe XXIII, and Fe XXIV, with simultaneous 20-60 km s{sup -1} upflows in million degree coronal lines from ions such as Fe XII-Fe XVI. The behavior of cooler, transition region ions such as O VI, Fe VIII, He II, and Fe X is more complex, but upflows were also observed in Fe VIII and Fe X lines. At a point close to strong energy input in space and time, the flare ions Fe XXII, Fe XXIII, and Fe XXIV reveal an isothermal source with a temperature close to 14 MK and no strong blueshifted components. At this location there is a strong downflow in cooler active region lines from ions such as Fe XIII and Fe XIV, on the order of 200 km s{sup -1}. We speculate that this downflow may be evidence of the downward shock produced by reconnection in the current sheet seen in MHD simulations. A sunquake also occurred near this location. Electron densities were obtained from density sensitive lines ratios from Fe XIII and Fe XIV. Atmospheric Imaging Assembly (AIA) observations from the Solar Dynamics Observatory are used with JHelioviewer to obtain a qualitative overview of the flare. However, AIA data are not presented in this paper. In summary, spectroscopic data from EIS are presented that can be used for predictive tests of models of chromospheric evaporation as envisaged in the Standard Flare Model.

Heteroepitaxial growth and surface structure of L1{sub 0}-MnGa(111) ultra-thin films on GaN(0001)  

SciTech Connect (OSTI)

L1{sub 0}-structured MnGa(111) ultra-thin films were heteroepitaxially grown on GaN(0001) under lightly Mn-rich conditions using molecular beam epitaxy. Room-temperature scanning tunneling microscopy (STM) investigations reveal smooth terraces and angular step edges, with the surface structure consisting primarily of a 2 × 2 reconstruction along with small patches of 1 × 2. Theoretical calculations were carried out using density functional theory, and the simulated STM images were calculated using the Tersoff-Hamman approximation, revealing that a stoichiometric 1 × 2 and a Mn-rich 2 × 2 surface structure give the best agreement with the observed experimental images.

Detection of $^{133}$Xe from the Fukushima nuclear power plant in the upper troposphere above Germany  

E-Print Network [OSTI]

After the accident in the Japanese Fukushima Dai-ichi nuclear power plant in March 2011 large amounts of radioactivity were released and distributed in the atmosphere. Among them were also radioactive noble gas isotopes which can be used as tracers to test global atmospheric circulation models. This work presents unique measurements of the radionuclide $^{133}$Xe from Fukushima in the upper troposphere above Germany. The measurements involve air sampling in a research jet aircraft followed by chromatographic xenon extraction and ultra-low background gas counting with miniaturized proportional counters. With this technique a detection limit of the order of 100 $^{133}$Xe atoms in litre-scale air samples (corresponding to about 100 mBq/m$^3$) is achievable. Our results provide proof that the $^{133}$Xe-rich ground level air layer from Fukushima was lifted up to the tropopause and distributed hemispherically. Moreover, comparisons with ground level air measurements indicate that the arrival of the radioactive plume at high altitude over Germany occurred several days before the ground level plume.

Dependence of the Mg-related acceptor ionization energy with the acceptor concentration in p-type GaN layers grown by molecular beam epitaxy  

SciTech Connect (OSTI)

Hall effect and capacitance-voltage C(V) measurements were performed on p-type GaN:Mg layers grown on GaN templates by molecular beam epitaxy with a high range of Mg-doping concentrations. The free hole density and the effective dopant concentration N{sub A}-N{sub D} as a function of magnesium incorporation measured by secondary ion mass spectroscopy clearly reveal both a magnesium doping efficiency up to 90% and a strong dependence of the acceptor ionization energy Ea with the acceptor concentration N{sub A}. These experimental observations highlight an isolated acceptor binding energy of 245{+-}25 meV compatible, at high acceptor concentration, with the achievement of p-type GaN:Mg layers with a hole concentration at room temperature close to 10{sup 19} cm{sup -3}.

Evaluating the evaluations: Evidence from energy efficiency programmes in Germany and the UK  

Science Journals Connector (OSTI)

Abstract To make robust judgments of an energy efficiency programme's economic effectiveness, we need to know how much energy and CO2 is actually being saved through the financial support it provides. But most evaluations of home retrofit energy efficiency programmes depend on calculated, rather than measured, levels of energy consumption. This fails to take into account the discrepancies that have been observed in practice, between calculated and actual energy consumption both before and after refurbishment. Evaluations of energy efficiency programmes ideally need to consider rebound effects, free rider effects, reduced savings due to insufficient technical quality, and discrepancies between actual and calculated pre-refurbishment energy consumption. This paper investigates and compares evaluations of two prominent energy efficiency programmes in the Germany and UK–the CO2-Building Rehabilitation Programme and the Supplier Obligation. We show that evaluations of the Supplier Obligation explicitly address most of the reduction effects whereas this is not the case for the CO2-Building Rehabilitation Programme.

VI.5 Recycling of plastic waste, rubber waste and end-of-life cars in Germany  

Science Journals Connector (OSTI)

Publisher Summary Among different types of consumer waste in Germany, plastic waste, rubber waste, and end-of-life cars are closely intertwined. Processing techniques applied to these types of consumer waste are identical in many cases. This chapter outlines these similarities and discusses each type of consumer waste. The regulations for plastic waste recycling only apply to private households. Regulations are limited to packaging waste with the ordinance on packaging waste being the legal provision. The recycling of packaging remnants from production or defective production units is partially organized by producers themselves. Energy recovery of plastic packaging is limited to combined heat and power stations. Packaging waste that cannot be submitted to mechanical recycling is usually treated by the means of feedstock recycling. The treatment of plastic waste comprises fragmentation, sizing, sorting, washing and drying, agglomeration, and granulation. Rubber waste is unsuitable for deposition at landfill sites because of poor compressibility, resilient surfaces, extremely long rotting time, and forming of cavities with air inclusion. An increased utilization of rubber waste in the production of new tires depends directly on the quality of the vulcanization process.

Long time experience with the development of HTR fuel elements in Germany  

Science Journals Connector (OSTI)

The development of spherical fuel elements for HTR-designs in Germany is discussed. Special attention is given to the development, production and characterization (incl. kernel and coatings) as well as to the irradiation and post-irradiation examination of the different coated particle systems. It has been demonstrated in various irradiation tests which were supplemented by heating tests that for a modular HTR power plant (with a thermal output of 200 MJ s?1) during the specified normal operation as well as in the case of incidents and even accidents, where the maximum fuel temperature will be below 1620 °C, the fission product release is very low. In this context, it must be mentioned that the present coated particle design has not yet been optimized for the combination of high burn-up and high temperature resistance under accident conditions. The TRISO fuel available is a result from fuel development for large HTR's with steam turbines in a time when the modular concept was not yet been invented although its capabilities inspired the design of modular reactors. Thus, there is still a huge potential for improvement of coated particles especially when plutonium or actinide burning is also taken into account.

Documentation of the Range 8C rehabilitation demonstration project at Hohenfels Training Area, West Germany  

SciTech Connect (OSTI)

Continued and intensive tactical training for the last 35 years at the Hohenfels Training Area (HTA), Federal Republic of Germany, has resulted in extensive environmental damage and reduced training realism. The US Corps of Engineers Construction Engineering Research Laboratory is developing an Integrated Training Area Management (ITAM) Program for the Seventh Army Training Command for use at HTA. Argonne National Laboratory was asked to assist in one element of the ITAM program, a training range rehabilitation demonstration project. The rehabilitation project was begun in 1986 on a 62-ha watershed that included about 16 ha of meadow with training damage typical of HTA. On the basis of amount of plant ground cover, type and degree of erosion, and soil properties, 10 rehabilitation prescriptions were developed to reestablish plant cover, control erosion, and improve training realism. Prescriptions were installed by a local contractor in September 1986. A monitoring program is under way to determine the effectiveness of this effort. Results and experience gained from this project will be used in the ITAM program and for rehabilitation training courses conducted at HTA.

Heating and cooling performance analysis of a ground source heat pump system in Southern Germany  

Science Journals Connector (OSTI)

Abstract This paper examines thermal performance of a ground source heat pump (GSHP) system. The GSHP system was installed in an office building in Nuremberg city of Germany. In order to evaluate system performance the GSHP system has been continuously monitored for 4 years. Heating and cooling performance of the GSHP system is analyzed based on the accumulated data. Major findings of this work include: (1) coefficient of performance (COP) is estimated to be 3.9 for a typical winter day and energy efficiency ratio (EER) is assessed to be 8.0 for a typical summer day. These results indicate that the GSHP system has a higher efficiency for building cooling than building heating. (2) For a long-term period, the seasonal energy efficiency ratio (SEER) of the GSHP system is observed to increase by 8.7% annually, whereas the seasonal COP is decreased by 4.0% over a 4-year period. The heating and cooling performance of the GSHP system migrates in opposite trend is caused by the unevenly distributed heating and cooling load of the building. This phenomenon deserves serious attention in the design of future GSHP systems in order to avoid the reducing of energy efficiency over long-term operation.

Options for CO2-lean hydrogen export from Norway to Germany  

Science Journals Connector (OSTI)

Norway is a nation with an abundant supply of energy, both from fossil and renewable resources. Due to limited domestic demand, Norway is today exporting large amounts of petroleum products. For the future, various options for export of CO2-lean energy exist, both from Northern and Southern Norway, and both from fossil sources (including carbon capture and storage), and renewable energies (particularly wind power). Transport vectors are hydrogen pipelines, liquid hydrogen ships and HVDC cables, and a plausible customer is central Europe due to its proximity, high population density and lack of domestic energy resources. Within the framework of the “NorWays” project, various options to deliver energy for hydrogen-based transportation from Norway to Germany were studied. Eight CO2-lean well-to-wheel energy export chains were evaluated with respect to efficiency, GHG emissions and other environmental impacts, costs and utilisation of Norwegian R&D experience. In the chosen scenarios, energy export via hydrogen pipelines and ships appeared energetically and economically interesting against existing approaches as NG and electricity export. Furthermore, increased utilisation of Norwegian R&D experience and higher value creation is anticipated by the export of a higher refined product.

Propane ammoxidation over the Mo-V-Te-Nb-O M1 phase: Reactivity of surface cations in hydrogen abstraction steps  

SciTech Connect (OSTI)

Density functional theory calculations (GGA-PBE) have been performed to investigate the adsorption of C3 (propane, isopropyl, propene, and allyl) and H species on the proposed active center present in the surface ab planes of the bulk Mo-V-Te-Nb-O M1 phase in order to better understand the roles of the different surface cations in propane ammoxidation. Modified cluster models were employed to isolate the closely spaced V=O and Te=O from each other and to vary the oxidation state of the V cation. While propane and propene adsorb with nearly zero adsorption energy, the isopropyl and allyl radicals bind strongly to V=O and Te=O with adsorption energies, {Delta}E, being {le} -1.75 eV, but appreciably more weakly on other sites, such as Mo=O, bridging oxygen (Mo-O-V and Mo-O-Mo), and empty metal apical sites ({Delta}E > -1 eV). Atomic H binds more strongly to Te = O ({Delta}E {le} -3 eV) than to all the other sites, including V = O ({Delta}E = -2.59 eV). The reduction of surface oxo groups by dissociated H and their removal as water are thermodynamically favorable except when both H atoms are bonded to the same Te=O. Consistent with the strong binding of H, Te=O is markedly more active at abstracting the methylene H from propane (E{sub a} {le} 1.01 eV) than V = O (E{sub a} = 1.70 eV on V{sup 5+} = O and 2.13 eV on V{sup 4+} = O). The higher-than-observed activity and the loose binding of Te = O moieties to the mixed metal oxide lattice of M1 raise the question of whether active Te = O groups are in fact present in the surface ab planes of the M1 phase under propane ammoxidation conditions.

STEM HAADF Image Simulation of the Orthorhombic M1 Phase in the Mo-V-Nb-Te-O Propane Oxidation Catalyst  

SciTech Connect (OSTI)

A full frozen phonon multislice simulation of high angle annular dark field scanning transmission electron microscopy (HAADF STEM) images from the M1 phase of the Mo-V-Nb-Te-O propane oxidation catalyst has been performed by using the latest structural model obtained using the Rietveld method. Simulated contrast results are compared with experimental HAADF images. Good agreement is observed at ring sites, however significant thickness dependence is noticed at the linking sites. The remaining discrepancies between the model based on Rietveld refinement and image simulations indicate that the sampling of a small volume element in HAADF STEM and averaging elemental contributions of a disordered site in a crystal slab by using the virtual crystal approximation might be problematic, especially if there is preferential Mo/V ordering near the (001) surface.

Photoionization cross-section analysis for a deep trap contributing to current collapse in GaN field-effect transistors  

Science Journals Connector (OSTI)

We perform a more incisive numerical analysis of the photon energy dependence of the photoionization cross section of a prominent deep trap (conventionally labeled as Trap 1) which had been found [Klein et al. Appl. Phys. Lett. 75 4016 (1999)] to act as a contributor to current collapse phenomena in GaN metal-semiconductor field-effect transistors. The analytical expression for the photoionization cross section of Trap 1 is taken in the form of a convolution of a temperature-independent electronic part with a thermally broadened Franck–Condon (FC) factor which also applies to the relevant regime of large lattice relaxation. For a direct comparison with earlier results we specialize the present analysis to an electronic cross-section part represented by the Lucovsky model in combination with the semiclassical (Gaussian) approximation for the FC factor. In qualitative accordance with an earlier estimation by Klein et al. we obtain a value of E O ?1.9? eV for the classical opticalionization energy in combination with a full width at half maximum of 0.64 eV. The latter implies on the assumption for the average phonon energy to be of order 50 meV an apparently unusually large magnitude D?1.1? eV for the Franck–Condon shift. This parameter constellation is equivalent to a thermal ionization (electron binding) energy E T =E O ?D of about E T ?0.8 eV. Such a location of Trap 1 near the middle of the upper half of the fundamental gap of GaN E T ?E g /4 is at clear variance to the earlier suggestion by Klein et al. for Trap 1 to be a midgap level. The present estimation offers a chance for detecting the Trap 1 also by deep-level transient spectroscopy measurements. An eventual availability of photoionization cross-section data for different temperatures is seen to be the prerequisite for a decisive reduction of residual uncertainties concerning the configuration coordinate diagram.

Geophysical exploration in the Lautertal at the Combat Maneuver Training Center, Hohenfels, Germany  

SciTech Connect (OSTI)

Geophysical exploration was conducted in the Lautertal at the Combat Maneuver Training Center, Hohenfels, Germany, to determine the shallow geological framework of a typical dry valley in this karstic environment. The complementary methods of electromagnetic surveying, vertical electrical soundings, and seismic refraction profiling were successful in determining the depth and configuration of the bedrock surface, the character of the unconsolidated deposits resting on the bedrock surface, and the nature of the bedrock surface. Channels and other depressions in the bedrock surface are aligned with structurally induced fractures in the bedrock. The unconsolidated deposits consist of coarse alluvium and colluvium, which are confined to these channels and other depressions, and fine-grained loam and loess, which cover most of the Lautertal. Wide ranges in the electrical and elastic parameters of the bedrock surface are indicative of carbonate rock that is highly fractured and dissolved at some locations and competent at others. Most local groundwater recharge occurs in the uplands where the Middle Kimmeridge (Delta) Member of the Maim Formation (Jurassic) is widely exposed. These carbonate rocks are known to be susceptible to dissolution along the fractures and joints; thus, they offer meteoric waters ready access to the main shallow aquifers lower in the Malm Formation. These same rocks also form the bedrock surface below many of the dry valleys, but in the Lautertal, the infiltration of meteoric waters into the subsurface is generally impeded by the surficial layer of fine-grained loam and loess, which have low hydraulic conductivity. Further, the rocks of the Middle Kimmeridge Member appear to be closely associated with the localized occurrence of turbidity in such perennial streams as the Lauterach.

Homogeneous AlGaN/GaN superlattices grown on free-standing (1100) GaN substrates by plasma-assisted molecular beam epitaxy  

SciTech Connect (OSTI)

Two-dimensional and homogeneous growth of m-plane AlGaN by plasma-assisted molecular beam epitaxy has been realized on free-standing (1100) GaN substrates by implementing high metal-to-nitrogen (III/N) flux ratio. AlN island nucleation, often reported for m-plane AlGaN under nitrogen-rich growth conditions, is suppressed at high III/N flux ratio, highlighting the important role of growth kinetics for adatom incorporation. The homogeneity and microstructure of m-plane AlGaN/GaN superlattices are assessed via a combination of scanning transmission electron microscopy and high resolution transmission electron microscopy (TEM). The predominant defects identified in dark field TEM characterization are short basal plane stacking faults (SFs) bounded by either Frank-Shockley or Frank partial dislocations. In particular, the linear density of SFs is approximately 5 × 10{sup ?5} cm{sup ?1}, and the length of SFs is less than 15 nm.

Adsorption of propane, isopropyl, and hydrogen on cluster models of the M1 phase of Mo-V-Te-Nb-O mixed metal oxide catalyst  

SciTech Connect (OSTI)

The Mo-V-Te-Nb-O mixed metal oxide catalyst possessing the M1 phase structure is uniquely capable of directly converting propane into acrylonitrile. However, the mechanism of this complex eight-electron transformation, which includes a series of oxidative H-abstraction and N-insertion steps, remains poorly understood. We have conducted a density functional theory study of cluster models of the proposed active and selective site for propane ammoxidation, including the adsorption of propane, isopropyl (CH{sub 3}CHCH{sub 3}), and H which are involved in the first step of this transformation, that is, the methylene C-H bond scission in propane, on these active site models. Among the surface oxygen species, the telluryl oxo (Te=O) is found to be the most nucleophilic. Whereas the adsorption of propane is weak regardless of the MO{sub x} species involved, isopropyl and H adsorption exhibits strong preference in the order of Te=O > V=O > bridging oxygens > empty Mo apical site, suggesting the importance of TeO{sub x} species for H abstraction. The adsorption energies of isopropyl and H and consequently the reaction energy of the initial dehydrogenation of propane are strongly dependent on the number of ab planes included in the cluster, which points to the need to employ multilayer cluster models to correctly capture the energetics of surface chemistry on this mixed metal oxide catalyst.

Propane ammoxidation over Mo–V–Te–Nb–O M1 phase: Density functional theory study of propane oxidative dehydrogenation steps  

Science Journals Connector (OSTI)

Abstract Propane ammoxidation to acrylonitrile catalyzed by the bulk Mo–V–Te–Nb oxides has received considerable attention because it is more environmentally benign than the current process of propylene ammoxidation and relies on a more abundant feedstock. This process is proposed to consist of a series of elementary steps including propane oxidative dehydrogenation (ODH), ammonia and O2 activation, \\{NHx\\} insertion into C3 surface intermediates, etc. Density functional theory calculations were performed here to investigate the three sequential H abstraction steps that successively convert propane into isopropyl, propene, and ?-allyl on cation sites in the proposed selective and active center present in the ab plane of the Mo–V–Te–Nb–O M1 phase. The initial H abstraction from propane was found to be the rate-limiting step of this process, consistent with both the proposed reaction mechanism for propane ammoxidation on the Mo–V–Te–Nb oxides and current understanding of V5+ as the active site for alkane activation on V-based oxides. Te=O was found to be significantly more active than V5+=O for the H abstraction from propane, which suggests that the surface and bulk Te species may be different. The role of Mo=O is most likely limited to being an H acceptor from isopropyl to form propene under ammoxidation conditions.

Heavy fuel oil fired CHP plant -- Impact on environment: Case Germany  

SciTech Connect (OSTI)

In 1995 Waertsilae NSD Finland Oy got the order to build a 14 MWe CHP (simultaneous heat and power) diesel power plant for Cerestar GMBH in Germany. The order consisted of a complete delivery, installation and commissioning of the fuel treatment system, the diesel engine with alternator, the process control system, the exhaust gas cleaning system (SCR and DESOX) and the heat recovery system. The factory producing starch is situated in the city of Krefeld close to Dusseldorf. The process integration of the diesel power plant into the existing factory was done in a close cooperation between the client and Waertsilae and the result is a CHP-plant suiting well into the existing factory. The diesel power plant went into operation in January 1996. The operating experience has been very encouraging, the annual running time is above 8,000 h and by the end of December 1997 about 16,300 running hours had been accumulated. The power plant is fulfilling the strict TA-LUFT emission limits and even half TA-LUFT values regarding NO{sub x} and SO{sub x}. The measured total efficiency of the power plant is above 90%. The choice of the most economical DESOX-method is dependent on several factors: investment and running cost, plant size, environmental legislation requirements, commercially available heavy fuel oil brands, etc. In small diesel plants the NaOH-scrubber is the most competitive desulfurization (DESOX) method, due to the lower investment cost compared to other DESOX-systems. A wet NaOH scrubbers system is installed. The used reagent is an about 50 wt-% aqueous NaOH solution. Low SO{sub x}-emissions of the flue gas is easily achieved by adjusting the pH of the scrubber liquid. The dissolved salt in the generated liquid end-product consists mainly of Na{sub 2}SO{sub 4}, due to the high oxygen content of the diesel flue gas. Running experiences have shown that the installed wet NaOH scrubber is easy to operate and suits the factory in Krefeld well.

Time-resolved photoluminescence, positron annihilation, and Al0.23Ga0.77N/GaN heterostructure growth studies on low defect density polar and nonpolar freestanding GaN substrates grown by hydride vapor phase epitaxy  

Science Journals Connector (OSTI)

Time-resolved photoluminescence(TRPL) and positron annihilation measurements as well as Al0.23Ga0.77N/GaN heterostructuregrowth by metalorganic vapor phase epitaxy were carried out on very low defect density polar c-plane and nonpolar m-plane freestanding GaN (FS-GaN) substrates grown by hydride vapor phase epitaxy. Room-temperature photoluminescence(PL) lifetime for the near-band-edge (NBE) excitonic emission of the FS-GaN substrates increases with increasing positron diffusion length (L +); i.e. decreasing gross concentration of charged and neutral point defects and complexes. The best undoped c-plane FS-GaN exhibits record-long L + being 116?nm. The fast component of the PL lifetime for its NBE emission increases with temperature rise up to 100?K and levels off at approximately 1.1?ns. The result implies a saturation in thermal activation of nonradiative recombination centers. The surface and interface roughnesses for a Si-doped Al0.23Ga0.77N/GaN/Al0.18Ga0.82N/GaN heterostructure are improved by the use of FS-GaN substrates in comparison with the structure fabricated on a standard GaN template. The emission signals related to the recombination of a two-dimensional electron gas and excited holes are recognized for an Al0.23Ga0.77N/GaN single heterostructuregrown on the c-plane FS-GaN substrate.

Atmospheric Radiation Measurement (ARM) Data from Black Forest Germany for the Convective and Orographically Induced Precipitation Study (COPS)  

DOE Data Explorer [Office of Scientific and Technical Information (OSTI)]

The primary goal of the ARM Program is to improve the treatment of cloud and radiation physics in global climate models in order to improve the climate simulation capabilities of these models. ARM maintains four major, permanent sites for data collection and deploys the ARM Mobile Facility (AMF) to other sites as determined. In 2007 the AMF operated in the Black Forest region of Germany as part of the Convective and Orographically Induced Precipitation Study (COPS). Scientists studied rainfall resulting from atmospheric uplift (convection) in mountainous terrain, otherwise known as orographic precipitation. This was part of a six -year duration of the German Quantitative Precipitation Forecasting (QPF) Program. COPS was endorsed as a Research and Development Project by the World Weather Research Program. This program was established by the World Meteorological Organization to develop improved and cost-effective forecasting techniques, with an emphasis on high-impact weather. A large collection of data plots based on data streams from specific instruments used at Black Forest are available via a link from ARM's Black Forest site information page. Users will be requested to create a password, but the plots and the data files in the ARM Archive are free for viewing and downloading.

Individual characteristics and stated preferences for alternative energy sources and propulsion technologies in vehicles: A discrete choice analysis for Germany  

Science Journals Connector (OSTI)

With respect to the German goal of a transition to a lead market for electromobility within a short time period, this paper empirically examines the preferences for alternative energy sources or propulsion technologies in vehicles and particularly for electric vehicles. The data stem from a stated preference discrete choice experiment with 598 potential German car buyers. In order to simulate a realistic future purchase situation, seven vehicle types were incorporated in each of the six choice sets, i.e. hybrid, gas, biofuel, hydrogen, and electric vehicles besides common gasoline and diesel vehicles. The econometric analysis with flexible multinomial probit models reveals that potential car buyers in Germany currently have a low stated preference for electric, hydrogen, and hybrid vehicles. While our paper also discusses the impact of common vehicle attributes such as purchase price or service station availability, it particularly considers the effect of socio-demographic and environmental awareness variables. The estimation results reveal that younger potential car buyers have a higher stated preference for hydrogen and electric vehicles, males have a higher stated choice of hydrogen vehicles, and environmentally aware potential car buyers have a higher stated preference for hydrogen and electric vehicles. These results suggest that common policy instruments such as the promotion of research and development, taxation, or subsidization in the field of electromobility could be supplemented by strategies to increase the social acceptance of alternative vehicle types that are directly oriented to these population groups. Methodologically, our study highlights the importance of the inclusion of taste persistence across the choice sets and a high number of random draws in the Geweke–Hajivassiliou–Keane simulator in the simulated maximum likelihood estimation of the multinomial probit models.

Aspen for short-rotation coppice plantations on agricultural sites in Germany: Effects of spacing and rotation time on growth and biomass production of aspen progenies  

Science Journals Connector (OSTI)

The suitability of agricultural sites for the production of woody biomass using fast-growing trees in short-rotation coppice plantations is being investigated in a joint multi-discipline project. The basis of this project are two trial plantations, one in Bavaria (south Germany) and the other in Hesse (central Germany). At the trial plantation in Bavaria (Abbachhof), six aspen progenies were planted in 1983 and tested for their suitability in different short-rotation periods (5 and 10 years) and three different spacings. At the other location in Hesse (Canstein), 14 aspen progenies were planted in 1986 and tested in a 10-year rotation period at one spacing. The progenies tested resulted from cross-pollinations of selected trees of European (Populus tremula L.) and American aspen (P. tremuloides Michx.). The trials show that hybrid aspen have a higher biomass production in short-rotations than progenies from European or American aspen. This is due to a lower mortality rate as well as to a higher growth rate. Even on sites low in nutrients and only average water availability hybrid aspen are capable of producing biomass on an average of 100 t/ha (wood and bark including branches, absolutely dry) within a 10-year rotation period. The results show that the harvesting should be more than 10 years in order to achieve a maximum average biomass-production per year.

SciTech Connect (OSTI)

Systematic nuclear resonance fluorescence (NRF) experiments on all nine stable (seven even-even and two odd-mass) Xe isotopes have been performed at the bremsstrahlung facility of the 4.3-MV Stuttgart Dynamitron accelerator. For the first time thin-walled, high-pressure gas targets (about 70 bar) with highly enriched target material were used in NRF experiments. Precise excitation energies, transition strengths, spins, and decay branching ratios were obtained for numerous states, most of them previously unknown. The systematics of the observed E1 two-phonon excitations (2{sup +}x3{sup -}) and M1 excitations to 1{sup +} mixed-symmetry states in the even-even isotopes are discussed with respect to the new critical point symmetry E(5). The fragmentation of these fundamental dipole excitation modes in the odd-mass isotopes {sup 129,131}Xe is shown and discussed. In the even-even nuclei several low-lying E2 excitations were observed.

Uranium ores and depleted uranium in the environment, with a reference to uranium in the biosphere from the Erzgebirge/Sachsen, Germany  

Science Journals Connector (OSTI)

The Erzgebirge (‘Ore Mountains’) area in the eastern part of Germany was a major source of uranium for Soviet nuclear programs between 1945 and 1989. During this time, the former German Democratic Republic became the third largest uranium producer in the world. The high abundance of uranium in the geological formations of the Erzgebirge are mirrored in the discovery of uranium by M. Klaproth close to Freiberg City in 1789 and the description of the so-called ‘Schneeberg’ disease, lung cancer caused in miners by the accumulation of the uranium decay product, radon, in the subsurfaces of shafts. Since 1991, remediation and mitigation of uranium at production facilities, rock piles and mill tailings has taken place. In parallel, efforts were initiated to assess the likely adverse effects of uranium mining to humans. The costs of these activities amount to about 6.5 109 Euro. A comparison with concentrations of depleted uranium at certain sites is given.

Possibilities and limitations of life cycle assessment (LCA) in the development of waste utilization systems - Applied examples for a region in Northern Germany  

SciTech Connect (OSTI)

Against the background of increasing concerns about climate change, the reduction of greenhouse gas emissions has become an integral part of processes in both the waste management and the energy industries. This is reflected in the development of new waste treatment concepts, in which domestic and commercial waste is treated with the aim of utilizing its energy content, while at the same time recycling as much of its material content as possible. Life cycle assessment (LCA) represents a method of assessing the environmental relevance of a waste management system, the basis of which is a material flow analysis of the system in question. GHG emissions from different options for thermal treatment and energy recovery from waste as applied to a region in Northern Germany have been analyzed by the LCA approach and an indicative LCA, which only considers those emissions resulting from operating stages of the system. Operating stages have the main share of emissions compared to pre-processing stages. Results show that through specific separation of waste material flows and highly efficient energy recovery, thermal treatment and energy generation from waste can be optimized resulting in reduction of emissions of greenhouse gases. There are also other areas of waste utilization, currently given little attention, such as the solar drying of sewage sludge, which can considerably contribute to the reduction of greenhouse gas emissions.

Is a German Harbour Porpoise much more sensitive than a British one? Comparative analyses of mandatory measures for the protection of Harbour Porposes (Phocoena phocoena) during Offshore Wind Farm ramming in Germany, Denmark and the UK  

Science Journals Connector (OSTI)

Offshore wind farms (OWF) will soon contribute to significant growth in the renewable energy sector. At present just a few OWF have been built. As of 2012 Germany has an offshore wind capacity of little more than 200 MW whereas Denmark has already reached 875 MW and the UK soon will reach 2.000 MW. There are plans for another 114 GW in EU countries with a cumulative investment of 211 billion Euro. This expansion of offshore wind energy needs to be organized in a sustainable way. The Habitat Directive has to be considered in each European country in the same way. Currently the environmental impacts of the underwater noise on porpoises caused by jack-hammers that are mostly used to drive the pile foundations into the seabed are assessed differently amongst the forerunners of offshore wind energy like Denmark Great Britain and Germany. This paper includes an overview of the possible applied measures for avoiding damages as well as obligatory measures and the different thresholds of European countries. The analysis concludes by identifying a need for international standardization. The paper is result of research as part of the PhD thesis "Strategies for Sustainable Development of Offshore Wind Energy" of the author.

OMV studies ethylene expansion in Germany  

SciTech Connect (OSTI)

OMV(Vienna) is evaluating plans to debottleneck its ethylene plant at Burghausen from 310,000 m.t./year to at least 400,000 m.t./year. Senior v.p. Jochen Berger says OMV is studying the limits to which the cracker can be expanded. {open_quotes}We`re pretty sure we can go to 400,000 m.t./year, but in two months we`ll have a better idea,{close_quotes} says Berger. The expansion will also depend on the future requirements of downstream operations at the Burghausen site, which include OMV plastics subsidiary PCD`s high-density polyethylene and polypropylene units and the vinyl chloride monomer and polyvinyl chloride units operated by Hoechst-Wacker joint venture Vinnolit.

Down syndrome clusters in Germany after the Chernobyl accident  

SciTech Connect (OSTI)

In two independent studies using different approaches and covering West Berlin and Bavaria, respectively, highly significant temporal clusters of Down syndrome were found. Both sharp increases occurred in areas receiving relatively low Chernobyl fallout and concomitant radiation exposures. Only for the Berlin cluster was fallout present at the time of the affected meiosis, whereas the Nuremberg cluster preceded the radioactive contamination by 1 month. Hypotheses on possible causal relationships are compared. Radiation from the Chernobyl accident is an unlikely factor, because the associated cumulative dose was so low in comparison with natural background. Microdosimetric considerations would indicate that fewer than 1 in 200 oocyte nuclei would have experienced an ionizing event from Chernobyl radioactivity. Given the lack of understanding of what causes Down syndrome, other than factors associated with increased maternal age, additional research into environmental and infectious risk factors is warranted. 23 refs., 4 figs., 2 tabs.

Experience with solar systems for heating swimming pools in Germany  

SciTech Connect (OSTI)

The results of the demonstration programme [open quotes]Efficient Use of Energy in Swimming Pool Construction[close quotes] has had a positive effect on the dissipation of solar systems for swimming pools. Infrared measurements show how a homogeneous flow can be achieved in the absorber field. The fact that solar systems are acceptable can be clearly in evidence that the behaviour of visitors to purely solar-heated pools with variable water temperature does not differ in principle from conventionally-heated pools with constant temperature. Economic considerations of the operation show that swimming pool solar systems are competitive with conventional heating systems.
