In the field of catalysis, oxide formation cannot be neglected under realistic conditions. Oxide
formation changes the properties of a surface and it was found that catalytic properties could
be attributed to oxides rather than to the pure metal surfaces [1]. Besides the formation of
superstructures by oxygen adsorption and bulk oxides, oxidation of a metal surface often
leads to complex two-dimensional structures, which are different from bulk oxides [2-6]. In
the case of Rh(111) the structure of the trilayer surface oxide has already been solved by a
combination of experimental and theoretical methods [6]. It was found that the Rh surface
oxide on Rh(111) is only kinetically stabilized and hinders the formation of a bulk oxide.
