Abstract

The virtual-crystal approximation in the framework of the tight-binding method is extended to include interactions between unlike second-nearest neighbors for semiconductor alloys. These interactions are determined by taking the experimentally observed bowing parameters of the energy gap as input information. Conclusions concerning the question of clustering are drawn and compared to experiment.
