Electrochemical thin film deposition in aqueous mixtures containing Cd2+, Zn2+, and thioacetamide has been investigated. It has been found that the atom-by-atom growth of well-crystallized CdS thin film preferentially takes place at the early stage of the reaction, followed by the cluster-by-cluster growth of the poorly crystallized ZnS outer layer, thus resulting in the formation of CdS/ZnS bilayer by a one-step synthesis.
