Structural, Chemical Composition and Optical Properties of CdTe Fabricated by Vacuum Evaporation Technique
CdTe polycrystalline thin films have been fabricated by vacuum evaporation technique. Their properties have been investigated using X-ray diffraction, energy dispersive spectroscopy, scanning electron microscope and uv-vis spectroscopy. The results showed that the CdTe thin films crystalized at hexagonal structure with lattice parameters a and c 6.45 Å and 7.66 Å respectively. The EDS results showed that the chemical composition is nonstoichiometry, slightly rich of Tellerium with Cd/Te of 0,9. It has a uniform shape with color homogenity and has an optical band gap at room temperature about 1.47 eV. Keywords:Vacuum evaporation, polycrystalline, cadmium telluride, thin films.
