Electrochemical synthesis of CuS(x)Se(1-x )thin film for supercapacitor application

摘要

The CuSxSe1-x thin films were deposited on conducting substrates using copper sulphate sodium thio-sulfate and selenium dioxide as a source of Cu, S, and Se by electrodeposition(ED) technique. The effect of the change in composition S and Se the structural and electrical properties of the CuSxSe1-x thin films was studied. The crystallite size, composition, microstructure, contact angle and capacitance studied using XRD, EDAX, SEM, CA, and CV. The X-Ray diffraction (XRD) graph reveals that the CuSxSe1-x films were polycrystalline in nature and CuS(0.6)Se(0.4 )shows crystallite size of 34 nm, Energy dispersive analysis X-Ray (EDAX), scanning electron microscopy (SEM) show the elemental composition and microstructures were changes with S and Se composition. The CuS(0.6)Se(0.4 )film show 31 degrees contact angle and specific capacitance of 159 F/g. (C) 2018 Published by Elsevier B.V.
