Abstract

Ultraviolet (UPS) and X-ray (XPS) photoemission spectra of quasi-two dimensional metal Ag2F are presented. Three prominent bands are found at about 2.0 eV, 4.6 eV and 6.0 eV from the Fermi level in the UPS spectrum. They are assigned to the F 2p state, the Ag 4d state and the mixture of the two states, respectively. The comparison of the photoemission spectra with a recent LAPW band calculation shows that the calculated 4d band is shifted toward the lower binding energy by about 1 eV relative to that of the experiment. This discrepancy suggests that the 16th band which forms a small ellipsoidal Fermi surface in the LAPW calculation may be above the Fermi level.
