Abstract
The electronic and optical properties of ZnxCd1−xSe are investigated using the empirical pseudopotential method (EPM). For the ternary alloy ZnCdSe, the virtual crystal approximation (VCA) is coupled with the pseudopotential method. The energies of Γ, X and L of ZnxCd1−xSe alloy versus concentration of Zn are calculated. Pseudocharge density and band structure of Zn0.5Cd0.5Se are also calculated. Other quantities such as refractive index, ionicity character by means of a recent model and transverse effective charge are calculated.
