Abstract
We report the use of optical pumping in p‐type GaxIn1−xAsyP1−y nearly lattice‐matched to InP. Analysis of the conduction‐electron spin‐polarized photoluminescence has been used to deduce the valence‐band light‐hole effective mass as a function of alloy composition. Our results are in good agreement with masses calculated using the k⋅p approximation.Keywords
