Abstract
Recently, Marsh and Inkson (1984) have suggested that there are substantial deviations between effective mass theory and pseudopotential theory in the description of electron scattering from GaAs-Ga1-xAlxAs interfaces. It is shown here that this conclusion is premature. A rigorous application of effective mass theory which takes into account the correct boundary conditions for a mass discontinuity is found to give quite good agreement with pseudopotential theory.Keywords
