Paper Abstract

Cathodic behavior of n-Type Cadmium Telluride is investigated in aqueous acidic and basic solutions by means of cyclic voltametry and in situ reflectanance measurements. The formation of cadmium layers is demonstrated in basic media wohereas no cadmium deposits are observed in acidic solution (pH = 0) under simular treatments. These results are explained by considering the variation with the pH value of the interface parameters (decomposition and hydrogen evolution potentials, band edges positions). It is shown that very uniform cadmium films of various thicknesses up to one micron can be grown on CdTe by this method.
