 Abstract: We use angle-resolved photoelectron spectroscopy to investigate the electronic structure of the clean and atomic oxygen covered Ag(110) surface. A comparison is made to results of surface band-structure calculations using a tight-binding method in a recursive layer-by-layer scheme. For the clean surface, where angle-resolved inverse photoemission data are also available, w obtain good agreement for all (except image potential) surface states. For the Ag(110)-p(2 × 1)-O surface, the electronic structure is calculated for a “buckled-row” and a “missing-row” reconstruction model. All occupied surface states are reproduced by both models where alternate silver 〈001〉 rows are displaced outward by 0.2 ± 0.2Å from the first layer and the oxygens are located 0.2± 0.2 Å above these. Angle-resolved inverse photoemission however would distinguish between the two reconstruction models since the unoccupied surface states are quite different. We also discuss the electronic structure of some other possible forms of oxygen adsorption on and absorption in silver single-crystal surfaces in relation to photoelectron spectroscopy.
