摘要：

The presence of Ba at a Zn(0001)-O surface (up to theta(Ba) similar to- 3 ML) gives rise to BaO, followed by a peroxo-type species (Ba, Zn) O-2(delta)- at the interface. Such peroxo species are also formed when a Ba-covered Zn surface(delta(Ba) similar to 0.3 ML) exposed to dioxygen at 200 K is warmed to 400 K. Peroxo formation occurs via the oxidation of O2- species. (C) 1994 Academic Press, Inc.
