High-Coverage Oxygen-Induced Surface Structures on Ag(111)
Journal article, 2014
Surface structures formed by exposing Ag(111) to atomic oxygen have been studied by X-ray photoelectron spectroscopy, scanning tunneling microscopy, and density functional theory calculations. From the combination of the experimental and theoretical results, a model is proposed for the 0.5 ML oxygen coverage with a c(4 x 8) periodicity. Moreover, we find that a bulk-like Ag2O phase starts to form at coverages above 0.5 ML.
