Abstract: The higher-order perturbation theory based on pseudopotential is used to calculate total energy, band gap at Jones-zone face and bulk modulus of CdS, CdSe and CdTe binary semiconductor compounds. The covalent correction term, which is approximately equal to third and fourth-order perturbation energy, is used in the present study. The ratio of covalent bond correction energy to second-order perturbation energy is about 15% and hence it is essential to study the electronic properties of semiconductor materials. Present theoretical results are found better than other available theoretical findings and good agreements of present finding of total energy, band gap at Jones-zone face and bulk modulus with the experimental data are achieved.
