Reconstruction of the oxygen covered Cu 3Au(110) surface investigated by low energy ion back scattering and LEED
Abstract
The Cu 3Au(110) surface has been investigated by 180° low energy ion scattering spectroscopy in impact collision mode with the detection of noble gas neutrals (NICISS) and low energy electron diffraction (LEED). Oxygen adsorption on the clean surface at room temperature leads to a (2 × 1) reconstruction. The reconstructed surface no longer contains gold in its topmost layer, but instead copper and oxygen atoms. The surface is composed of CuOCuOCu chains in the <001> direction. In the <110> direction every second row is missing. Evidence for this "added-row" model will be given.
