Analysis of Structural and Electrical Properties of Aluminium Doped Lead Sulphide (PbS) Thin Film Prepared by CBD Method
Abstract:We have deposited PbS and Al doped PbS thin films by chemical bath deposition. Lead acetate and thiourea were used as sources of Pb 2+ and S 2respectively. The films were deposited at a pH of 12.5. The deposited films were further annealed at three different temperatures 250 p C, 300 p C, 350 p C. The structural analysis reveals that PbS has a preferential growth at (200) planes and high crystalline PbS were obtained when the films were annealed at 300p C. Crystallite size for all the films varies from 30 to 5… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
