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 ...
Molecular dynamics simulation study of Ni2+ adatom diffusion on the NiO (001) surface

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

Using molecular dynamics simulations we studied the cation adatom diffusion on the NiO(001) surface. We found that there are two equilibrium adatom positions: one over an oxygen ion, that is raised by as much as 30% at ...
