«Optical-Energy Properties of the Bulk and Thin-Film Cadmium Telluride (CdTe)»
519–533 (2018)

PACS numbers: 61.05.cp, 68.37.Hk, 68.55.J-, 71.15.Mb, 71.20.Nr, 73.20.At, 78.20.Ci

The results of the experimental and theoretical studies of the optical-energy properties of a single crystal and thin films of CdTe are presented. The synthesis, structural and optical studies of the CdTe single crystal and thin films deposited on the mica are performed. By the method of pseudopotential, the dynamics of parametersÔÇÖ change of the electron subsystem in the CdTe crystal and films is theoretically studied. As established, the CdTe is characterized by direct band gap. Based on the density of states, the genesis of the conduction and valence bands is revealed. Using the KramersÔÇôKronig relations, the absorption and reflection spectra of the CdTe are obtained. Theoretical models and experimental data are in a good agreement.

Keywords: single crystal, thin film, band-energy structure, density of states, optical functions
