Abstract
We present an electron spectroscopy investigation of the MgO(100)/Ag(100) oxide-metal interface electronic structure. We find that the O states strongly hybridize with the Ag band and only weakly with the Ag band. As a result of these interactions, a substantial density of states with a large oxygen antibonding character is pushed above the Fermi level, determining the chemical bonding at the oxide-metal interface. One striking consequence of such an electronic structure is the strong chemical activity of the interface toward dissociative chemisorption.
