Surface-state electron dynamics in noble metals
P. M. Echenique, J. Osma, M. Machado +3
Theoretical investigations of surface-state electron dynamics in noble metals are reported. The dynamically screened interaction is computed, within many-body theory, by going beyo…

Self-energy of image states on copper surfaces
I. Sarria, J. Osma, E. V. Chulkov +2
We report extensive calculations of the imaginary part of the electron self-energy in the vicinity of the (100) and (111) surfaces of Cu. The quasiparticle self-energy is computed…

Role of the intrinsic surface state in the decay of image states at a metal surface
J. Osma, I. Sarria, E. V. Chulkov +2
The role of the intrinsic surface state () in the decay of the first image state () at the (111) surface of copper is investigated. Inelastic linewidths are evaluated fro…
