Abstract
The electronic structure of the Cu(100) surface has been calculated self-consistently. The calculation predicts a strong surface-state/surface-resonance band near the top of the bulk Cu band which has not been observed in previous calculations. The large attenuation in the experimental photoemission signal at the top of the band which is independent of photon energy and which occurs when various species are chemisorbed on Cu(100) is attributed to disturbance of this surface-state band by the chemisorbed atoms.
