Abstract
Abstract Electron scattering mechanisms have been investigated in Se- and S-doped GaxIn1-xSb alloys by measuring the Hall mobilities as a function of hydrostatic pressures up to 25 kbar at temperatures down to 4.2 K. The analysis of the data shows that the Brooks-Herring theory of ionized impurities scattering could fit the experimental variations only overa narrow range of low pressures before carrier freeze-out into a resonant impurity level sets in. At higher pressures, good agreement between theory and experiment could be obtained by introducing an additional scattering mechanism due to the short-range central cell impurity potential.
