Heat transfer between a nano-tip and a surface
Pierre-Olivier Chapuis, Jean-Jacques Greffet, Karl Joulain +1
We study quasi-ballistic heat transfer through air between a hot nanometer-scale tip and a sample. The hot tip/surface configuration is widely used to perform nonintrusive confined…
Effects of temperature and surface step on the incipient plasticity in strained aluminium studied by atomistic simulations
Pierre Hirel, Sandrine Brochard, Laurent Pizzagalli +1
Atomistic simulations using an EAM potential are carried out to investigate the first stages of plasticity in aluminum slabs, in particular the effect of both temperature and step…
Comparison between classical potentials and ab initio for silicon under large shear
Julien Godet, Laurent Pizzagalli, Sandrine Brochard +1
The homogeneous shear of the {111} planes along the <110> direction of bulk silicon has been investigated using ab initio techniques, to better understand the strain properties of…
Undissociated screw dislocations in silicon: calculations of core structure and energy
Laurent Pizzagalli, Pierre Beauchamp, Jacques Rabier
The stability of the perfect screw dislocation in silicon has been investigated using both classical potentials and first-principles calculations. Although a recent study by Koizum…
Ab initio Study of Misfit Dislocations at the SiC/Si(001) Interface
Giancarlo Cicero, Laurent Pizzagalli, Alessandra Catellani
The high lattice mismatched SiC/Si(001) interface was investigated by means of combined classical and ab initio molecular dynamics. Among the several configurations analyzed, a dis…
Stability of undissociated screw dislocations in zinc-blende covalent materials from first principle simulations
Laurent Pizzagalli, Pierre Beauchamp, Jacques Rabier
The properties of perfect screw dislocations have been investigated for several zinc-blende materials such as diamond, Si, -SiC, Ge and GaAs, by performing first principles calc…
