摘要
We present a theoretical study for the band-gap energy and structural properties of partially ordered InxGa1-xP alloys. Partially ordered alloys axe modeled through a statistical ensemble of small crystal structures defined in a 64-site periodic cell. Configurations axe generated according to the degree of ordering. The dependence of calculated properties on the long-range-order parameter is found to follow simple functional relationships. Structural anisotropies scale accurately with the square of the order parameter.
