Abstract

The composition of polar {0001} surfaces of CdS was investigated by Auger electron spectroscopy. Both the A (0001) or cadmium face and the B (000¯1) or sulphur face showed sulphur enrichment. This enrichment is attributed to the forward scattering of sulphur below the surface and the subsequent exposure of these atoms through continued sputtering. The effect of carbon contamination on the S/Cd ratio on both faces was investigated. The decrease of this ratio with increased carbon contamination is explained in terms of differences in the escape depths of the sulphur and cadmium Auger electrons.
