Abstract
The valence-band offset between GaAs and AlGaAs has been found to be independent of crystal orientation, as deduced from measurements of the two-dimensional hole densities in As/GaAs heterojunctions. An analysis of the charge transfer yields a valence-band offset of 0.39±0.02 of the energy-gap difference.
