Abstract | ||
The Tin Telluride thin films of obliquely and normal deposited were prepared using thermal evaporation method at pressure of 10-6 torr on glass substrates at room temperature. The optical band gap of films has been determined from the transmission and absorption spectra. The optical band gap of as-grown films has been found to have direct band gap of ~(1.8, 1.62, 1.47) eV for deposition angle θ = (0 ̊ , 40° , 70 ̊ ) respectively. The optical band gap of SnTe thin films decreases with angle of deposition increases. | ||
