LEED suggests that the atomically clean pyrite surface prepared in this manner is unreconstructed. XPS S 2p data for this surface show no evidence for a monosulfide species coexisting with the disulfide moiety that characterizes pyrite. This experimental observation contrasts with many prior studies that prepared pyrite surfaces by cleavage or mechanical cutting and observed a monosulfide species. We argue that a pyrite surface prepared directly from the as-grown surface may better represent a natural surface than does a preparation method such as cleavage. This content is PDF only.
