Cation adatom diffusion on the NiO(001) surface by molecular dynamics simulation

Karakasidis, T. E.; Papageorgiou, D. G.; Evangelakis, G. A. (2001)

We present results concerning the diffusion of Ni2+ adatom on the (001) surface of NiO obtained by molecular dynamics simulations based on a rigid ion potential model. A wide temperature region was covered ranging from ...

Cation vacancy diffusion on the NiO(001) surface by molecular dynamics simulations

Karakasidis, T. E.; Evangelakis, G. A. (1999)

We present results concerning the cation vacancy diffusion mechanisms occurring on the NiO(001) surface along with their corresponding migration energies. Using a rigid ion potential and molecular dynamics simulations we ...

Three-dimensional stability of free convection vortices in the presence of a magnetic field

Dimopoulos, D.; Pelekasis, N. (2012)

Three-dimensional (3D) stability of 2D vortical flow of a liquid metal in a cavity of square cross section is examined. Vortices are produced as a result of free convection and internal heating in the cavity in the presence ...
