Thickness Dependent Structural and Optical Properties of Cadmium Selenide Thin Films

Article Preview

Abstract:

In this paper structural and optical properties of CdSe thin films with different thickness deposited by thermal evaporation under vacuum onto glass substrates are presented. The structural investigations performed by means of XRD technique showed that the films have a polycrystalline and hexagonal (würtzite) structure. The values of some important parameters of the studied films (absorption coefficient and optical bandgap energy) are determined from transmission spectra. The values of the optical bandgap energy (E_g) calculated from the absorption spectra, ranged between 1.67 - 1.74 eV.
