Abstract

Abstract Although adsorption of simple gases is not detected on CdS by analytical means, oxidation is induced, for example, by exposure to a negative corona discharge [1] as well as by electron stimulation [2–4]. In the former case it was found that O attaches only to S, but in the latter case Cd is also oxidized. In this paper we investigate these processes by SIMS and XPS in an attempt to characterize and understand further these differences in behavior.
