Abstract :
The structural, electronic and optical properties of cubic CdS1 xTex alloys, with Te-concentrations varying from 0% up to 100% are
investigated. The calculations are based on the total-energy calculations using the full potential-linearized augmented plane wave (FPLAPW)
method. The exchange and correlation potential is treated by the generalized-gradient approximation (GGA) for the totalenergy
calculations, while for electronic properties in addition to that the Engel–Vosko (EV-GGA) formalism was also applied. The
ground state properties for all Te-concentrations are presented. The optical dielectric constant is also determined for both the binary
and their related ternary alloys.
