摘要：

CdTe deposition on Ag(111) was obtained by Electrochemical Atomic Layer Epitaxy (ECALE) method, that is by the alternated underpotential deposition of tellurium and cadmium. The voltammetric analysis of the first Te-UPD and Cd-UPD peaks indicates a mechanism of two-dimensional growth, which is consistent with an epitaxial growth. The ratio Cd/Te determined on the basis of electrochemical measurements is very close to the 1:1 stoichiometric ratio, which is indicative of a compound formation. (C) 2000 Elsevier Science Ltd.
