Abstract
The simple virtual crystal approximation for empirical pseudopotential model calculations of the energy gap as a function of composition in zincblende semiconductor alloys is shown to be equivalent to an extreme case of the component atoms being displaced from the alloy lattice sites. A simple method, utilizing this result, is suggested for fitting the theoretical results to experiment.Keywords
