Title: Silver photo-diffusion and photo-induced macroscopic surface deformation of Ge{sub 33}S{sub 67}/Ag/Si substrate

Abstract

Ge-chalcogenide films show various photo-induced changes, and silver photo-diffusion is one of them which attracts lots of interest. In this paper, we report how silver and Ge-chalcogenide layers in Ge{sub 33}S{sub 67}/Ag/Si substrate stacks change under light exposure in the depth by measuring time-resolved neutron reflectivity. It was found from the measurement that Ag ions diffuse all over the matrix Ge{sub 33}S{sub 67} layer once Ag dissolves into the layer. We also found that the surface was macroscopically deformed by the extended light exposure. Its structural origin was investigated by a scanning electron microscopy.

  • Silver complexes of the anionic forms of 2-(diphenylphosphino)benzenethiol [2-(Ph{sub 2}P)C{sub 6}H{sub 4}SH] (1) 2-(diphenylphosphino)-6-(trimethylsilyl)benzenethiol [2-(Ph{sub 2}P)-6-(Me{sub 3}Si)C{sub 6}H{sub 3}SH] (2), and 2-(diphenylphosphinyl)-6-(trimethylsilyl)benzenethiol [2-(Ph{sub 2}PO)-6-(Me{sub 3}Si)C{sub 6}H{sub 3}SH] (3) have been prepared by an electrochemical procedure and characterized by spectroscopic (IR, {sup 1}H, {sup 13}C, and {sup 31}P NMR) methods, and ligand 3 and [Ag{sub 4}{l_brace}2-(Ph{sub 2}P)-6-(Me{sub 3}Si)C{sub 6}H{sub 3}S{r_brace}{sub 4}] (5) and [Ag{sub 4}{l_brace}2-(Ph{sub 2}PO)-6-(Me{sub 3}Si)C{sub 6}H{sub 3}S{r_brace}{sub 4}] (6) complexes were characterized by X-ray crystallographic techniques. The (5) compound is tetranuclear with an array of four silver atoms bridged by four sulfur atoms. Each silver atom has a distortedmore » trigonal [AgS{sub 2}P] environment with each ligand acting as P,S bidentate S-bridging ligand. The (6) complex is also tetranuclear, but in this case two of the silver atoms are [AgO{sub 2}S{sub 2}] tetracoordinated and the other two Ag atoms are [AgS{sub 2}] two coordinated.« less
  • Evolution of surface roughness in epitaxial Si{sub 0.7}Ge{sub 0.3} alloys grown on Si(001) as a function of temperature (200-600 C), thickness ({ital t}=7.5-100 nm), and substrate miscut were investigated by atomic force microscopy and quantified in terms of the height-difference correlation function {ital G}({rho}), in which {rho} is lateral distance and [{ital G}({rho}{r_arrow}{infinity})]{sup 1/2} is proportional to the surface width. The films were deposited by ultrahigh vacuum ion-beam sputter deposition at 0.1 nms{sup {minus}1}. Strain-induced surface roughening was found to dominate in alloys grown on singular Si(001) substrates at {ital T}{sub {ital s}}{approx_gt}450{degree}C where [{ital G}({rho}{r_arrow}{infinity})]{sup 1/2} initially increases withmore » increasing {ital t} through the formation of coherent islanding. The islands are preferentially bounded along {l_angle}100{r_angle} directions and exhibit 105 faceting. This tendency is enhanced, with much better developed {l_angle}100{r_angle} islands separated by deep trenches{emdash}of interest for growth of self-assembled nanostructures{emdash}in films grown on Si(001)-4{degree}[100]. Increasing the film thickness above critical values for strain relaxation leads to island coalescence and surface smoothening. At very low growth temperatures ({ital T}{sub {ital s}}{le}250{degree}C), film surfaces roughen kinetically, due to limited adatom diffusivity, but at far lower rates than in the higher-temperature strain-induced regime. Si{sub 0.7}Ge{sub 0.3} alloy surfaces are smoother, while the films exhibit larger critical epitaxial thicknesses, than those of pure Si films grown in this temperature regime. There is an intermediate growth temperature range, however, over which the alloy film surfaces remain extremely smooth even at thicknesses near critical values for strain relaxation. This latter result is of potential importance for device fabrication. {copyright} {ital 1996 American Institute of Physics.}« less
  • The novel silver(I)thioantimonates(III) [C{sub 4}N{sub 2}H{sub 14}][Ag{sub 3}Sb{sub 3}S{sub 7}] (I) (C{sub 4}N{sub 2}H{sub 12}=1,4-diaminobutane) and [C{sub 2}N{sub 2}H{sub 9}]{sub 2}[Ag{sub 5}Sb{sub 3}S{sub 8}] (II) (C{sub 2}N{sub 2}H{sub 8}=ethylenediamine) were synthesized under solvothermal conditions using AgNO{sub 3}, Sb, S and the amines as structure directing molecules. Both compounds crystallize as orange needles with lattice parameters a=6.669(1) A, b=30.440(3) A, c=9.154(1) A for I (space group Pnma), and a=6.2712(4) A, b=15.901(1) A, c=23.012(2) A, {beta}=95.37(1){sup o} for II (space group P2{sub 1}/n). In both compounds the primary building units are trigonal SbS{sub 3} pyramids, AgS{sub 3} triangles and AgS{sub 4} tetrahedra.more » In I the layered [Ag{sub 3}Sb{sub 3}S{sub 7}]{sup 2-} anion is constructed by two different chains. An [Sb{sub 2}S{sub 4}] chain running along [100] is formed by vertex sharing of SbS{sub 3} pyramids. The second chain contains a Ag{sub 3}SbS{sub 5} group composed of the AgS{sub 4} tetrahedron, two AgS{sub 3} units and one SbS{sub 3} pyramid. The Ag{sub 3}SbS{sub 5} units are joined via S atoms to form the second chain which is also directed along [100]. The layered anion is then obtained by condensation of the two individual chains. The organic structure director is sandwiched by the inorganic layers and the shortest inter-layer distance is about 6.4 A. In II the primary building units are linked into different six-membered rings which form a honeycomb-like layer. Two such layers are connected via Ag-S bonds of the AgS{sub 4} tetrahedra giving the final undulated double layer anion. The structure directing ethylenediamine cations are located in pairs between the layers and a sandwich-like arrangement of alternating anionic layers and organic cations is observed. The inter-layer separation is about 5.4 A. Both compounds decompose in a more or less complex manner when heated in an argon atmosphere. The optical band gaps of about 1.9 eV for the two compounds proof the semiconducting behavior. For II the conductivity was measured with impedance spectroscopy and amounts to {sigma} {sub 295K}=7.6x10{sup -7} {omega}{sup -1} cm{sup -1}. At 80 deg. C the conductivity is significantly larger by one order of magnitude. - Graphical abstract: In the new silver thioantimonate, [C{sub 4}N{sub 2}H{sub 14}][Ag{sub 3}Sb{sub 3}S{sub 7}], the layered [Ag{sub 3}Sb{sub 3}S{sub 7}]{sup 2-} anion is constructed by two different chains.

  • Reversible and reproducible formation and dissolution of silver conductive filaments are studied in Ag-photodoped thin-film Ge{sub 40}S{sub 60} subjected to electric fields. A tip-planar geometry is employed, where a conductive-atomic-force microscopy tip is the tip electrode and a silver patch is the planar electrode. We highlight an inherent “memory” effect in the amorphous chalcogenide solid-state electrolyte, in which particular silver-ion migration pathways are preserved “memorized” during writing and erasing cycles. The “memorized” pathways reflect structural changes in the photodoped chalcogenide film. Structural changes due to silver photodoping, and electrically-induced structural changes arising from silver migration, are elucidated using Raman spectroscopy.more » Conductive filament formation, dissolution, and electron (reduction) efficiency in a lateral device geometry are related to operation of the nano-ionic Programmable Metallization Cell memory and to newly emerging chalcogenide-based lateral geometry MEMS technologies. The methods in this work can also be used for qualitative multi-parameter sampling of metal/amorphous-chalcogenide combinations, characterizing the growth/dissolution rates, retention and endurance of fractal conductive filaments, with the aim of optimizing devices.« less
  • Epitaxial growth of a compressively strained Ge quantum well (QW) on an ultrathin, 345 nm thick, Si{sub 0.4}Ge{sub 0.6}/LT-Si{sub 0.4}Ge{sub 0.6}/Si(001) virtual substrate (VS) has been demonstrated. The VS, grown with a low temperature Si{sub 0.4}Ge{sub 0.6} seed layer on a Si(001) substrate, is found to be fully relaxed and the Ge QW is fully strained. The temperature dependence of Hall mobility and carrier density clearly indicates a two-dimensional hole gas in the Ge QW. At room temperature, which is more relevant for electronic devices applications, the samples show a very high Hall mobility of 1235 cm{sup 2} V{sup -1}more » s{sup -1} at a carrier density of 2.36x10{sup 12} cm{sup -2}.« less
