Stable unidimensional arrays of coherent strained islands
Nicolas Combe, Pablo Jensen, Jean-Louis Barrat
We investigate the equilibrium properties of arrays of coherent strained islands in heteroepitaxial thin films of bidimensional materials. The model we use takes into account only…
Changing shapes in the nanoworld
Nicolas Combe, Pablo Jensen, Alberto Pimpinelli
What are the mechanisms leading to the shape relaxation of three dimensional crystallites ? Kinetic Monte Carlo simulations of fcc clusters show that the usual theories of equilibr…
Diffusion of gold nanoclusters on graphite
L. J. Lewis, P. Jensen, N. Combe +1
We present a detailed molecular-dynamics study of the diffusion and coalescence of large (249-atom) gold clusters on graphite surfaces. The diffusivity of monoclusters is found to…
Growth of nanostructures by cluster deposition : a review
Pablo Jensen
This paper presents a comprehensive analysis of simple models useful to analyze the growth of nanostructures obtained by cluster deposition. After detailing the potential interest…
Kinetics of shape equilibration for two-dimensional islands
Pablo Jensen, Nicolas Combe, Hernán Larralde +3
We study the relaxation to equilibrium of two dimensional islands containing up to 20000 atoms by Kinetic Monte Carlo simulations. We find that the commonly assumed relaxation mech…
The effect of a modulated flux on the growth of thin films
Pablo Jensen, Bernd Niemeyer
Thin films are usually obtained by depositing atoms with a continuous flux. We show that using a chopped flux changes the growth and the morphology of the film. A simple scaling an…
