Abstract
We calculate the quasiparticle band structures of GaAs and AlAs and compare them with previous experimental assignments. Generally good agreement is obtained, except for the L conduction-band minimum in AlAs, which is found to be 0.8±0.2 eV above the X minimum rather than 0.3 eV as found in the literature. A new interpretation of the experimental data is therefore proposed.Keywords
