Thickness Dependent Optical Parameters of Vacuum Evaporated Cadmium Telluride Thin Films
International Journal of Renewable Energy & Biofuels
Vacuum evaporated polycrystalline CdTe thin films were deposited on to glass substrates and optical parameters were determined by envelope technique. Thin films were characterized by optical transmission spectroscopy in the spectral range 290 - 1000 nm. The refractive index, extinction coefficient, optical conductivity and loss…
