Abstract:
Abstract: Different thickness of Cu۲S thin films were prepared by vacuum evaporation under a pressure of ۱۰-۶ torr at an evaporation rate of ۳Å /sec. Cu۲S has direct band gap energy and indirect band gap energy at ۱.۲eV and ۱.۸ eV respectively. This paper presents the analysis of structural and optical properties of the Cu۲S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotometer. XRD studies showed ploycrystallinity of CuXS thin films at higher thickness. Optical spectra of Cu۲S film exhibit high transmittance in the visible region and high absorbance in the near infra-red region. Moreover, the optical property of the film confirms that transmission mainly depends on the thickness of the film. Structural and resistivity property reveals that Cu۲S film at higher thicknesses shows slight deviations in stoichiometry. Possible applications of the Cu۲S thin films are also discussed.
