STUDY OF THE PHYSICAL-PROPERTIES OF SPRAYED CDS THIN-FILMS

CdS films have been prepared by spray pyrolysis and characterized by several methods. The spray solution is made of cadmium chloride or cadmium acetate and thiourea. Optical and compositional properties and structure of the CdS films have been investigated. An analysis of the film's structure, preferred cyrstallographic orientation and presence of impurity phases have been obtained using X-ray diffraction technique as well as infrared spectroscopy. The visible absorption measurements have been carried out for the study of the impurity phases. Quantitative Auger analysis shows the composition of the spray solution and a post-spray heat treatment have also been investigated. © 1979 AIME.
