Surface effects on the electronic energy loss of charged particles entering a metal surface
A. Garcia-Lekue, J. M. Pitarke
Surface effects on the electronic energy loss of charged particles entering a metal surface are investigated within linear-response theory, in the framework of time-dependent densi…
Metal Surface Energy: Persistent Cancellation of Short-Range Correlation Effects beyond the Random-Phase Approximation
J. M. Pitarke, J. P. Perdew
The role that non-local short-range correlation plays at metal surfaces is investigated by analyzing the correlation surface energy into contributions from dynamical density fluctu…
The role of surface plasmons in the decay of image-potential states on silver surfaces
A. Garcia-Lekue, J. M. Pitarke, E. V. Chulkov +2
The combined effect of single-particle and collective surface excitations in the decay of image-potential states on Ag surfaces is investigated, and the origin of the long-standing…
Image-potential-induced states at metal surfaces
P. M. Echenique, J. M. Pitarke, E. V. Chulkov +1
The unequivocal observation in the early 1980s of a new class of unnocupied surface states that are bound to the vacuum level of a variety of metal surfaces has led over the last t…
