POSTER

Abstract

We report effect of pressure on electronic {\&} optical properties of Cadmium Chalcogenide. The theoretical computational studies of Cadmium Chalcogenide are carried out using the full-potential linear augmented plane wave (FP-LAPW) method. In this approach the Generalized-gradient-approximation (GGA) is used for the exchange--correlation (XC) potential. We have calculated the equilibrium lattice constant, electronic band structure dispersion, total {\&} partial density of electron states, band gap, bulk modulus, and its pressure derivative. The calculated parameters are found in good agreement with experiment and other theoretical results. Furthermore, optical constants such as dielectric functions, refractive indices, reflectivity, absorption coefficient, optical conductivitity, loss functions of stable Cadmium chalcogende S were calculated for photon energies at ambient {\&} high pressure.
