Summary: | The electronic structure of the Ag(110)p(2×1)O surface was investigated by angle-resolved photoemission spectroscopy. The orbital symmetries of the O
2p–Ag
4d antibonding states were determined with the use of polarized light. A tight-binding two-dimensional energy band calculation including substrate contributions was made to reproduce the experimental surface band dispersions. The Slater–Koster two-center integrals between O
2p and Ag
4d, 5s, 5p orbitals were determined as fitting parameters. Using the same parameters, we calculated the oxygen-induced change in the density of states in Ag
4d band region, and could fully explain the experimentally observed spectral change as a results of oxygen-induced energy shifts as well as intensity changes. The Slater–Koster two-center integrals of oxygenmetal (Ni, Cu, Ag) orbitals were discussed as a function of the interatomic distance. |
