Evidence for alloy scattering from pressure-induced changes of electron mobility in In1−xGaxAsyP1−y

Abstract

The electron mobility in the quaternary alloy In1−xGaxAsyP1−y has been measured at pressures up to 16 kbar which produce significant changes in the effective mass. Both the pressure dependence and the temperature dependence indicate that alloy scattering has a strong influence on the electron mobility.
