Abstract

In this work, results on the preparation and characterization of ZnSe thin films obtained by electrodeposition are presented. Voltammetric curves were recorded in order to characterize the electrochemical behavior of the Zn+2/SeO2 system. Thin films were deposited potentiostatically from an unstirred, deareated aqueous solution onto Pt or ITO glass substrates. The underpotential deposition (UPD) of Se, Zn, as well as the alternate layers of Zn/Se/Zn on polycrystalline Pt electrodes by voltammetry are reported. The deposits morphologies were characterised by FEG and AFM.
