Electrodeposition of Ternary CdZnS Semiconductor Thin Films Using a S-Modified Polycrystalline Au Electrode

Abstract

ectrochemical deposition of CdZnS thin films on thepolycrystaline Au electrode. Initialy, an Au substrate is electrochemically modified with a sulfur layer. In the secondstep, the layer is electroreduced to S2- in the electrolyte dosed with the requisite amount of Cd2+ and Zn2+ ions togenerate CdZnS films in situ. This approach was validated using a combination of linear sweep voltametry andelectrochemical quartz crystal microgravimetry. Thus synthesized CdZnS thin films have diferent composition dependingon the composition of electrolytes. CdZnS thin films are characterized by energy-dispersive X-ray analysis and Ramanspectroscopy.
