d holes and the electronic structure of transition- and noble-metal thin films and surfaces

We point out that d holes are probably present in the non-self-consistent copper monolayer band structure of Kar and Soven. Contrary to the statement of Kar and Soven, this indicates that self-consistency probably has important qualitative effects on the copper monolayer band structure. This implies that self-consistency probably also has important qualitative effects on calculated surface behavior in transition and noble metals. We point out some features that are physically desirable to be included in a proper treatment of the thin-film electronic structure. Also we briefly discuss thin-film calculations for d-band metals by other workers.
