Atomic scale surface disorder (defects) has an important — if not dominating — influence on the physical and chemical properties of solid surfaces, e. g. on their reactive and. catalytic behavior. This holds certainly for both soliđ/gas and solid/liquid interfaces. In this work a technique is described, Photoemission of Adsorbed Xenon (PAX), which enables a surface characterization on the atomic scale under ultrahigh vacuum conditions.
The information obtained, namely the relative concentration of chemical and structural defects as well as local surface potential differences and local fields arising from them, appears equally important for an understanding of soliđ/gas and solid/liquid interfaces.
