Abstract

The adsorption and desorption of CO on the hydroxylated, O-terminated polar ZnO(000) surface has been studied using He-atom scattering. The experimental results reveal the formation of a physisorbed ordered CO overlayer.

In addition to recording angular distributions of elastically scattered He atoms, also the dynamical properties of the CO overlayer have been investigated using inelastic He-atom scattering. With the aid of electronic structure calculations a loss peak with an energy transfer of 7.2 meV is assigned to the frustrated translation of the CO molecule normal to the surface.
