http://www.ioffe.ru/SVA/NSM/Semicond/GaN/ Web16 okt. 2010 · The minimum metallic conductivities and mobilities, the critical concentrations of main impurities and majority charge carriers, and the compensation coefficients of the n-GaAs, p-Ge, and p-CdSnAs2〈Cu〉 compounds have been presented. It has been shown that experimental data agree with the concept of mobility threshold.
WebGaAs Fig. 1 SIMS profiles of doping elements across the GaAs tunnel junction grown by LT LPE. We intended to make the tunnel junction SCRs with characteristics similar to those of the tunnel junctions in MSCs [1,2]. Concentration of Te and Ge atoms as impurities in GaAs tunnel p+-n+ junction were of the order of 1020 cm-3, (Fig.1) 0.00.51.01.52 ... http://pvlab.ioffe.ru/pdf/8AV.3.27.pdf
WebGaAs/GaSb tandem cells stacks have been irradiated by 3 MeV electrons. BOL efficiency of the cells for this experiment was 25.5 – 26.2% (AM0, 100 suns). The 17.5% EOL efficiency and 0.68 remaining factor of efficiency have been recorded in the GaAs/GaSb tandem after 1·1015cm-23 MeV electron exposure (Fig. 8). Webthe intensity and an effective growth rate of the phase of the average wave field, the Ioffe-Regel parameter (k) c at the mobility edges can be calculated and takes values from 0.3 to 1.2 depending on ρ. Thus, the Ioffe-Regel criterion of localization k< (k) c = const. ∼ 1 is valid only qualitatively and cannot be used as a quantitative
