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 Webelements. GaAs was first created by Goldschmidt and reported in 1929, but the first reported electronic properties of III–V compounds as semiconductors did not appear until 1952 [1]. The GaAs crystal is composed of two sublattices, each face centered cubic (fcc) and offset with respect to each other by half the diagonal of the fcc cube. This ...
