Our study, based on interpolation methods, looked at the composition dependence of the energy band gap E/sub g/ in ternary and quaternary semiconducting solid solutions based on zinc, cadmium, and lead chalcogenides. Change in the energy band gap dependent on composition is not linear in most ternary systems. The nonlinear character of the composition dependent energy band gap for solid solutions based on A/sup II/B/sup VI/compounds may be explained from the point of view of a psuedopotential model. In the case of four-component solid solutions, we made use of a diagram of the composition dependence of the energy band gap in quaternary semiconductors. We calculated the energy band gap dependence on composition for a wide range of ternary compounds based on zinc, cadmium, and lead chalcogenides.
