摘要：
This paper reports a study of the electrodeposition of ZnSe on Pt electrodes in a sulfuric acid solution at pH 2.0 with the purpose of producing stoichiometric films. The film's properties were evaluated for different Zn/Se ratios. The films were deposited at different potentials (-0.2, -0.5, -0.7 and -0.9 V) and characterized by X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), X-ray Fluorescence (XRF) and non-contact 3D optical profilometry (3D-OP). Band gap, photocurrent, carrier number and flat-band potentials were determined. The films with higher photocurrent, carrier number, and crystallinity were obtained at -0.9 V; these films were p-type and presented 1:1 stoichiometry. (C) 2016 Elsevier B.V. All rights reserved.
