The scattering of conduction electrons from the GaAs-Ga 1-x Al x As heterojunction is calculated for a number of alloy concentrations. It is shown that the excitation of evanescent states derived from the higher conduction minima play a major part in the scattering process. Substantial deviations from effective-mass theory are found. It is shown how the numerical results may be incorporated into an evaluation of quantum well and superlattice systems.
