Abstract

Substrate temperature is one of the important deposition parameters, which dictates many physical properties of thin films to a large extent. This paper deals with the effect of substrate temperature on the optical properties of Chromium films in the thickness range 5-80 nm. Soon after the growth the films were taken out of vacuum chamber and used in the transmittance measurements using DK2 Ratio Recording Spectrometer in the visible region of incident radiation, for both the films grown at substrate temperatures 27^DEGC and 180^DEGC. From the transmittance data of the films, we have evaluated the optical constants, refractive index, band gap and extinction coefficient for both the films. Using Lambert's Law the absorption coefficient is also calculated for both the films.
