摘要：

The nonlinear variation of the fundamental energy gap E(g) as a function of composition x observed in A(I)B(III)C2VI chalcopyrite-structure alloys is discussed. The downward optical-bowing parameter c observed in these alloys is analyzed in terms of current models given in the literature. A relationship between c and the difference in electronegativities-DELTA-X of the atoms mixed to form the alloy is obtained. Also, an expression to predict the E(g)-vs-x curve for these alloys is proposed and good agreement with experimental data is found.
