Abstract

Inverse photoemission and impact collision ion scattering spectroscopy were used to study the dynamical behaviour of the Cu(110)-(2x1)O surface. In contrast to the clean Cu(110) surface, there is a linear increase of the mean square displacements of the copper surface atoms with temperature, which can be described by a Debye temperature of 240 K in agreement with surface phonon calculations. A possible explanation is that the adsorption of oxygen removes the surface stress present on the clean Cu(110) surface and leads to a stable bond configuration.
