ULTRAVIOLET PHOTOEMISSION-STUDIES OF MOLECULAR ADSORPTION ON OXIDE SURFACES

This paper reviews the current status of ultraviolet photoemission (UPS) measurements of the interaction of molecules with the surfaces of metal oxides. A brief summary of the electronic, geometric and compositional properties of atomically clean oxide surfaces is given, followed by a survey of the various adsorbate/substrate systems that have been investigated by UPS. Essentially all of that work to date has been on single-crystal oxide substrates. A brief description is also given of the various theoretical methods that are being used to study molecule/oxide interactions. © 1979.
