Statistics modification under monomer diffusion
Georges Sitja
The diffusion and coalescence of individual atoms on a nanostructured surface are treated in a purely statistical way. From this, analytical formulas are derived which, from a know…
Molecular Beam Study of the CO Adsorption on a Regular Array of PdAu Clusters on Alumina
Georges Sitja, Claude R Henry
The adsorption kinetics of CO on PdAu bimetallic clusters, containing 140 12 atoms and a composition varying between 0% and 55% of Pd atoms, is investigated by a pulsed molec…
Particle size effect on the Langmuir-Hinshelwood barrier for CO oxidation on regular arrays of Pd clusters supported on ultrathin alumina films
Georges Sitja, Héloïse Tissot, Claude Henry
The Langmuir-Hinshelwood barrier (ELH) and the pre-exponential factor (LH) for CO oxidation have been measured at high temperature on hexagonal arrays of Pd clusters supported o…
Regular Arrays of Pt Clusters on Alumina: A New Superstructure on AlO/NiAl (111)
Georges Sitja, Aude Bailly, Maurizio de Santis +2
Alumina ultrathin films obtained by high temperature oxidation of a NiAl (111) surface are a good template to grow regular arrays of metal clusters. Up to now two hexagonal org…
