On the electron mobility in slightly compensated heavily doped GaAs at low temperatures

D. N. Quang, N. N. Dat, D. Vanan

The electron mobility at low temperatures is calculated for a slightly compensated heavily doped sample of GaAs which undergoes a thermal treatment. Account is taken of high-temperature ionic correlation and low-temperature electronic screening as well. The numerical result is found to be in very good agreement with experimental data, especially at the highest impurity concentrations.
