Linear response theory of activated surface diffusion with interacting adsorbates
R. Martinez-Casado, A. S. Sanz, J. L. Vega +2
Activated surface diffusion with interacting adsorbates is analyzed within the Linear Response Theory framework. The so-called interacting single adsorbate model is justified by me…
Stochastic theory of lineshape broadening in quasielastic He atom scattering with interacting adsorbates
R. Martinez-Casado, J. L. Vega, A. S. Sanz +1
The activated surface diffusion of interacting adsorbates is described in terms of the so-called interacting single adsorbate approximation, which is applied to the diffusion of Na…
Quasielastic He atom scattering from surfaces: A stochastic description of the dynamics of interacting adsorbates
R. Martinez-Casado, J. L. Vega, A. S. Sanz +1
The study of diffusion and low frequency vibrational motions of particles on metal surfaces is of paramount importance; it provides valuable information on the nature of the adsorb…
Line Shape Broadening in Surface Diffusion of Interacting Adsorbates with Quasielastic He Atom Scattering
R. Martinez-Casado, J. L. Vega, A. S. Sanz +1
The experimental line shape broadening observed in adsorbate diffusion on metal surfaces with increasing coverage is usually related to the nature of the adsorbate-adsorbate intera…
A generalized Chudley-Elliott vibration-jump model in activated atom surface diffusion
R. Martinez-Casado, J. L. Vega, A. S. Sanz +1
Here the authors provide a generalized Chudley-Elliott expression for activated atom surface diffusion which takes into account the coupling between both low-frequency vibrational…
Quasi-elastic peak lineshapes in adsorbate diffusion on nearly flat surfaces at low coverages: the motional narrowing effect in Xe on Pt(111)
R. Martinez-Casado, J. L. Vega, A. S. Sanz +1
Quasi-elastic helium atom scattering measurements have provided clear evidence for a two-dimensional free gas of Xe atoms on Pt(111) at low coverages. Increasing the friction due t…
