Ab-initio study of the anomalies in the He atom scattering spectra of H/Mo(110) and H/W(110)
Bernd Kohler, Paolo Ruggerone, Matthias Scheffler
Helium atom scattering (HAS) studies of the H-covered Mo(110) and W(110) surfaces reveal a twofold anomaly in the respective dispersion curves. In order to explain this unusual beh…
Anomalies in He atom scattering spectra of the H-covered Mo(110) and W(110) surfaces

Helium atom scattering (HAS) studies of the H-covered Mo(110) and W(110) surfaces reveal a twofold anomaly in the respective dispersion curves. In order to explain this unusual beh…
Scattering of rare-gas atoms at a metal surface: evidence of anticorrugation of the helium-atom potential-energy surface and the surface electron density
Max Petersen, Steffen Wilke, Paolo Ruggerone +2
Recent measurements of the scattering of He and Ne atoms at Rh(110) suggest that these two rare-gas atoms measure a qualitatively different surface corrugation: While Ne atom scatt…
Force calculation and atomic-structure optimization for the full-potential linearized augmented plane-wave code WIEN
Bernd Kohler, Steffen Wilke, Matthias Scheffler +2
Following the approach of Yu, Singh, and Krakauer [Phys. Rev. B 43 (1991) 6411] we extended the linearized augmented plane wave code WIEN of Blaha, Schwarz, and coworkers by the ev…
Enhanced electron-phonon coupling at the Mo and W(110) surfaces induced by adsorbed hydrogen
Bernd Kohler, Paolo Ruggerone, Matthias Scheffler +1
The possible occurrence of either a charge-density-wave or a Kohn anomaly is governed by the presence of Fermi-surface nesting and the subtle interaction of electrons and phonons.…
Frustrated H-induced Instability of Mo(110)
P. Ruggerone, B. Kohler, S. Wilke +1
The large interest in the properties of transition metal surfaces has been recently fostered by inelastic helium atom scattering experiments carried out by Hulpke and Luedecke. Sha…
