First principles study of the Si(557)-Au surface
Daniel Sanchez-Portal, Richard M. Martin
We have performed a density functional study of fifteen different structural models of the Si(557)-Au surface reconstruction. Here we present a brief summary of the main structural…
Van der Waals contribution to the inelastic atom-surface scattering
Maider Machado, Daniel Sanchez-Portal
A calculation of the inelastic scattering rate of Xe atoms on Cu(111) is presented. We focus in the regimes of low and intermediate velocities, where the energy loss is mainly asso…
Excited states dynamics in time-dependent density functional theory: high-field molecular dissociation and harmonic generation
Alberto Castro, M. A. L. Marques, Julio A. Alonso +2
We present a theoretical description of femtosecond laser induced dynamics of the hydrogen molecule and of singly ionised sodium dimers, based on a real-space, real-time, implement…
Ag induced zero- and one-dimensional nanostructures on vicinal Si(111)
J. Kuntze, A. Mugarza, J. E. Ortega
The formation of a Ag stabilized regular step lattice on vicinal Si(111) miscut towards [11-2] is reported. The step bunching characteristic of the clean surface is prevented by a…
