Abstract

The mobility of the two-dimensional electron gas in a square quantum well of ${\mathrm{In}}_{0.53}$${\mathrm{Ga}}_{0.47}$As is calculated over the temperature range 4\char21{}300 K, including the effects of ionized impurity, alloy, deformation-potential acoustic, piezoelectric, and polar-optic phonon scatterings. A numerical iterative solution of the Boltzmann equation is employed. Agreement with the experimental data for quantum wells of width 100 A\r{} is satisfactory.
