Cadmium selenide thin films were deposited on a gold substrate by the Electrochemical Atomic Layer Deposition (ECALD) method. Detailed investigations of electrodeposition of selenium on gold and cadmium on previously deposited selenium on gold allowed to find the best conditions for CdSe synthesis. The elemental analysis was carried out by stripping voltammetry and energy dispersive spectroscopy (EDS). The analysis of thin films obtained after different number of ECALD cycles suggests stoichiometric ratio very close to the semiconductor compound. Additionally, the analysis were completed by Raman spectroscopy, X-ray diffraction and scanning electron microscopy (SEM) for films obtained after different number of ECALD cycles.
