摘要

A systematic study has been carried out on properties of CdS thin films grown on glass substrates by thermal route and growth parameters have been optimized to achieve near stoichiometry. Raman spectroscopy of the films has been carried out to get more insight on chemical and structural information of the films. Photoluminescence study was carried out to get the knowledge of defect-states which play major role in transport mechanisms. In order to obtain electrical parameters, Hall measurement has been carried out by van der Pauw's technique at room temperature. Also, variation of electrical resistivity of the films at temperature range 20-300 K has been studied. Finally effect of post deposition annealing on the structural, optical and electrical properties of these films has been studied.
