Abstract: The structural, optical and electrical properties of cadmium sulphide (CdS) thin films. Structural identification was done by XRD method at 2θ lying between 0º and 80º. The XRD results showed that the deposited films were polycrystalline with cubic structure having the plane as preferred growth. SEM was utilized in the morphological study of the films. The optical characteristics of CdS deposited on the glass substrate have been investigated from the absorption spectrum with wavelength from 350 to 600 nm. Further, optical constants were studied using UV-Visible absorption spectrum. The dielectric constant and dielectric loss of CdS thin films were found at various temperatures between 50 Hz to 5 MHz. The dielectric constant was evaluated as a function of frequency at various temperatures. The activation energy was determined and was about 0.24eV. Photoconductivity study established the nature of positive photoconductivity of CdS thin films.
