Structure analysis for cesiated-copper photoemission
Abstract
Using the Chodorow potential we have conducted a band-by-band analysis of the structure in the photoemission from cesiated copper and have determined the location and extent k→ space of the optical transitions involved. We show that the Chodorow potential yields copper d bands accurate to 0.1 eV, that low-energy photons lead to transitions near the surface of the Brillouin zone, and that free-electron bands are responsible for very localized activity while d bands yield activity which is extended in k→ space. © 1973 The American Physical Society.
