Structural, optical and electrical properties of nanocrystalline cadmium sulphide thin films deposited by novel chemical route

Abstract

Nanocrystalline semiconducting cadmium sulphide(CdS ) thin films have been deposited on glass substrate by relatively simple, quick and cost effective chemical bath route. The deposition kinetics played important role to get good quality nanocrystalline films with uniform thickness. Hence, the preparative parameters such as concentration, temperature, deposition time, pH of solution have been optimized. The characterization of as deposited thin films was carried out for the structural, compositional, surface morphological, optical and electrical properties using X-ray diffraction (XRD), EDAX, Scanning electron microscopy (SEM), UV-VIS Spectra and dc two point probe method.
