Abstract
Recently Zachau, Kash, and Masselink [Phys. Rev. B 44, 4048 (1991)] determined hole-subband dispersions in quantum wells experimentally with the use of hot-electron-acceptor luminescence. We present here results of multiple-band calculations, which are in very good agreement with these experiments. We also discuss the effects of subband anisotropy and its effect on the line shape. When the broadening is sufficiently small we predict a double-peak structure.
