Abstract

A tight binding formalism within virtual crystal approximation in which, the effects of composition disorder and bonds relaxation are involved, is applied to the quaternary system ZnyCd1−ySexTe1−x so as to compute its energy band gap and predict the ionic character. A new model, calculating the relaxation of bonds for the quaternary alloys is presented. The electronic parameters of the quaternary alloy considered are calculated as function of x composition. Very good agreement is obtained between the available experimental data and our results.
