Alloys of zinc chalcogenides exhibit both some of the smallest (for ZnS/sub x/Se/sub 1-//sub x/) and the largest (for ZnS/sub x/Te/sub 1-//sub x/) optical bowing observed in isovalent semiconductor systems. A theoretical analysis of this effect, by use of self-consistent band-structure techniques for ordered 50%-50% alloys in the CuAu-I structure, predicts correct bowing parameters and chemical trends, yet suggests a physical model which is altogether different from the virtual-crystal model.
