Title: Optical Properties Of {beta}-FeSi2 Thin Films Grown By Magnetron Sputtering

Abstract

{beta}-FeSi2 semiconductor thin films have been grown on Si(100) and Si(111) substrate at room temperature by unbalanced magnetron sputtering. The thicknesses of {beta}-FeSi2 thin films have been prepared to have value between 0.3-1{mu}m. Optical characteristic of the {beta}-FeSi2 films have been deduced using Fourier Transform Infrared Spectroscopy (FT-IR) in the wavelength range 1000-2000nm. The {beta}-FeSi2 films have been determinated to have optical direct band gap from the plot of ({alpha}h{upsilon})2 vs. h{upsilon} The direct band gap values of the films have been observed to vary between 0.82-0.89 eV depending on the type of substrates.
