Abstract

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.
Keywords: Thin films, SnTe, Obliquely Deposited, Optical band gap,
transmission analysis.
