Review of Photoelectron and Auger Data for the High-Temperatuare Superconductors
Abstract
A review of the photoelectron and Auger data reported for the recently discovered high temperature superconductors reveals that the surfaces of these materials are highly reactive to adsorbed gases. The Cu-O bonds appear to be highly covalent, indeed, the Cu-O covalency increases with Tc in these materials. The screening response to creation of a core hole, as reflected in the LV-VVV Auger satellite, is suggestive of the excitonic mechanism for the superconductivity.
