Abstract

In this paper, tin oxide (SnO2) thin films were deposited by vacuum thermal evaporation technique at a pressure  10-5 torr and a substrate temperature of 80 C. The surface roughness of the thin films was determined from  atomic force microscopy images. From the optical transmission and reflection spectra, recorded in the  wavelength range 300-1100 nm, the optical constants of the SnO2 thin films, such as the absorption coefficient, α, refractive index, n, and optical band gap energy, Eg, were determined.
