Abstract

We report adsorption studies on clean and modified surfaces of NiO, Cr2O3 and Al2O3. Small molecules such as NO, CO and H2O are adsorbed. The oxides are studied as bulk single crystals as well as as single crystal films. We are able to discriminate between adsorption on ideal terrace sites and defect sites by using EEL-spectra of surface states.

Employing various methods, e.g. ARUPS, HREELS and NEXAFS, we characterize the bonding between molecules and oxide substrates and show that concepts known from molecule metal interactions cannot directly be transferred to oxide surfaces.
