Abstract
Semiconducting Zinc sulphide (ZnS) thin films were deposited on glass substrate using relatively simple, quick chemical bath deposition method (CBD) using the mixed aqueous solution of zinc sulphate, thiourea and ammonia. The ammonia was used as the complexing agents. The preparative parameters such as concentration, temperature, deposition time, pH of solution have been optimized. Thin film of ZnS with different thickness were prepared by changing the deposition time at 850c. The characterization of thin films was carried out for the structural, surface morphological, optical and electrical properties. The thin films we characterized by using X-ray diffraction (XRD), Scanning electron microscopy (SEM), UV-VIS Spectra and d.c. two point probe method. The effect of thin film thickness on optical and electrical properties has been studied. _________________________________________________
