[en] A hard sphere model is used to interpret atomic transport processes in indium-lead alloys. The experimental data lead to hard core diameters of 3.04A for indium and 3.40A for lead. The distances between the origin and the first minimum of the pair potential curves are 3.1A and 3.3 A for indium and lead respectively. Thus, within the accuracy of the data, the results obtained from theory and experiment are in good agreement

[en] The temperature-dependent PL properties of GaN-rich In_xGa_1-xN alloys is investigated and S-shaped temperature dependence is observed in all InGaN samples. It is found that the origin of localization effect in samples A and B are different from that in sample C. For samples A and B, In content fluctuations should be the origin of localization effect, while the localization effect can be attributed to In-rich clusters and metallic indium inclusions for sample C. In addition, the band-tail model is modified and the modified band-tail model is used to investigate the degree of localization effect in the three samples. (author)

[en] The methods of differential thermal, X-ray phase, microstructural analysis and measurements of microhardness are used to plot Cd-InP polythermal cross section. Unknown inclusions are found in alloys subjected to extreme quenching at temperatures above 500 deg C

[en] We investigated superconducting AuIn₂ by point-contact spectroscopy. Andreev reflexion was observed with nearly full excess current at contact sizes down to 0.15 nm. This implies, together with a large superconducting coherence length of 11 μm, almost ideal retroreflectivity. At the onset of lateral confinement of the ballistic electrons the Andreev-derived spectra broaden dramatically due to inelastic scattering at defects or the strain field near the contact. Lateral confinement does not suppress Andreev reflexion. (orig.). With 5 figs

[en] We report resistive measurements of the transition temperature of InGa alloys in the range of the fct structure in In. These results are interpreted in terms of the role of the ionic mass in superconductivity

[en] The electrical transport properties, namely, the electrical resistivity (𝜌), the thermoelectric power (Γ) and thermal conductivity (𝜎) of In_1-xBi_x binary alloy were calculated from the pseudopotential form factors and Percus–Yevick (PY) hard sphere structure factors of Ashcroft and Langreth. The well-known empty core model potential of Ashcroft is used with seven different local field correction functions in the present computation and found suitable for present study. It is concluded that the contrast of present and experimental findings is highly encouraging. (author)
