| Abstract: | We report on a synchrotron radiation photoemission spectroscopy study of mixed GaSxSe1?x crystals. The most prominent composition effect in the valence band is an increase by ～ 0.4 eV of the energy separation between the pz states and the px, py states as x increases from 0 to 1. The repulsion in energy is accompanied by a progressive mixing of these states in k-space regions far from the zone boundaries. |
