Optical Properties of CulnSi Nanocomposite Thin Film Deposited by Magnetron Co-Sputtering

Article Preview

Abstract:

Thin CuInSi nanocomposite films were prepared by magnetron co-sputtering. The structures of CuInSi nanocomposite films were detected by X-ray diffraction(XRD); XRD studies of the annealed films indicate the presence of CuInSi, the main crystal phase peak is at 2θ=42.400°. The transmittance (T) spectra of the films were measured by Shimadzu UV-2450 double beam spectrophotometer. The band gap has been estimated from the optical absorption studies and found to be about 1.40 eV, but changes with purity of CuInSi.
