Primary Reactions in the Photocorrosion of CdSe Through Photocapacitance Measurements

Abstract

junctions have been investigated through photocapacitance measurements in single and in double beam (i.e., with an auxiliary band‐to‐band laser light superimposed) conditions. Two surface states, and, two lattice defects, located at and , and a bulk state located at , have been resolved. The analysis of the results as a function of the solution composition shows that both surface states and are involved in the corrosion mechanism: the upper surface state corresponds to elemental selenium whereas the lower one corresponds to a Cd‐related chemical intermediate. It is also shown that both lattice defects act as preferential surface sites where localized corrosion takes place
