Multiple fabrications of crystalline CdS thin films from a single bath by EICD in acidic aqueous solution of Cd2+ and thiourea complex

摘要

Multiple fabrications of crystalline CdS thin films have been realized by electrochemically induced chemical deposition (EICD) from a single acidic aqueous bath of stable Cd2+-thiourea complexes. Repeated depositions up to five times from the same bath have been proven to yield CdS thin films with essentially the same quality and thickness, owing to the absence of chemical decomposition of the precursor.
