Abstract: We propose a model for the partially ordered Ga0.5In0.5P alloys in which the CuPt structure is always retained. A long-range order parameter is defined in terms of the cation potentials on the group-III sublattice. Using this model we studied the electronic band structure of Ga0.5In0.5P alloys as a continuous function of the order parameter using the empirical pseudopotential method. Trends in the fundamental energy gap and effective masses are obtained. We found that the anisotropy in the effective masses is enhanced by ordering.
