Abstract
Subject headings
Close
- Spectroscopic signatures of vibrational excitations on initially oxidized Be(0001) are identified by a combination of electron energy loss spectroscopy and density functional calculations. Prominent spectral features are due to vibrations in a Be-Omixing layer. Scanning tunneling microscopy indicates that initial oxidation occurs locally in the form of islands. The acoustic surface plasmon persists on the oxygen-covered surface. Its dispersion has been determined along the (Gamma) over bar (K) over bar direction and is virtually identical to the dispersion of the acoustic surface plasmon of the clean surface.
