Abstract
Electron drift and Hall mobilities in Ga0.47In0.53As are calculated over the temperature range 77 to 300K. Mathiessen's rule is not used: instead, all the relevant scattering rates are directly included in the Boltzmann equation which is solved by the numerical iterative technique. The alloy scattering potential is determined by fitting the calculated values to the experimental data for samples for which the effective masses have been measured. The alloy scattering potential is found to be different for different samples, varying from 0.7 to 1 eV.Keywords
