Synergistic coupling in ab initio-machine learning simulations of dislocations
Petr Grigorev, Alexandra M. Goryaeva, Mihai-Cosmin Marinica +2
Ab initio simulations of dislocations are essential to build quantitative models of material strength, but the required system sizes are often at or beyond the limit of existing me…
Self-Organized Growth of Nanoparticles on a Surface Patterned by a Buried Dislocation Network
F. Leroy, G. Renaud, A. Letoublon +3
The self-organized growth of Co nanoparticles with 10 nm periodicity was achieved at room temperature on a Ag(001) surface patterned by an underlying dislocation network, as shown…
Interaction of carbon clusters with Ni(100) : Application to the nucleation of carbon nanotubes
Hakim Amara, Christophe Bichara, François Ducastelle
In order to understand the first stages of the nucleation of carbon nanotubes in catalytic processes, we present a tight-binding Monte Carlo study of the stability and cohesive mec…
Absolute surface energy determination
J. J. Metois, P. Muller
Experimental determination of absolute surface energies remains a challenge. We propose a simple method based on two independent measurements on 3D and 2D equilibrium shapes comple…
Lattice diffusion and surface segregation of B during growth of SiGe heterostructures by molecular beam epitaxy: effect of Ge concentration and biaxial stress
A. Portavoce, P. Gas, I. Berbezier +3
Si1-xGex/Si1-yGey/Si(100) heterostructures grown by Molecular Beam Epitaxy (MBE) were used in order to study B surface segregation during growth and B lattice diffusion. Ge concent…
Enhancement of Exciton Emission from Zno Nanocrystalline Films by Pulsed Laser Annealing
Igor Ozerov, Madjid Arab, Viatcheslav I. Safarov +4
Pulsed ArF laser annealing in air and in hydrogen atmosphere improves the optical properties of ZnO nanostructured films. Independently on the ambient atmosphere, laser annealing p…
