Structural stability and energetics of nickel clusters, Nih (N = 3 - 459), have been inves tigated by molecular-dynamics simulations, A size-dependent empirical model potential energy function has been used in the simulations. Stable structures of the microclusters with sizes N = 3 - 55 and clusters generated from fee crystal structure with sizes N = 79 - 459 have been determined by molecular-dynamics simulations. It has been found that the fivefold symmetry appears on the surface of the spherical clusters. The average coordination number shows a size-dependent characteristic, on the other hand the average nearest-neighbor distance does not show a size-dependence.

Melting and fragmentation of nickel nanoparticles: Molecular-dynamics simulations Gunes, B; Erkoç, Şakir (2000-12-01) Melting and fragmentation behaviors of Ni-429 cluster have been studied with molecular-dynamics simulations using a size-dependent empirical model potential energy function. To monitor thermal behaviors of the cluster, we calculated some physical quantities such as average potential energy per atom, specific heat, radial atomic distribution, bond length distribution, average interatomic distance, nearest neighbor distance and average coordination number as a function of temperature. The roles of the surface...
Molecular-dynamics simulation of radiation damage on copper clusters Erkoç, Şakir (2000-07-01) The effect of radiation damage on copper clusters has been investigated by performing molecular-dynamics simulation using empirical potential energy function for interaction between copper atoms. The external radiation is modeled by giving extra kinetic energy in the range of 5- 50 eV to initially chosen atom in the cluster. It has been found that the atom having extra kinetic energy dissociates independently from the amount of given energy in the studied range.
Molecular-dynamics simulations of water clusters Erkoç, Şakir; Guneyler, E (2000-07-01) The local minimum geometries and corresponding energy values of water clusters, [(H2O)(n), n = 2-8], have been investigated by using the molecular dynamics simulation method. In the simulations two different potential energy functions of central-force model, CF and CF2, have been used. Particular attention was paid to investigate the effectiveness of these two empirical potential energy functions. CF has been used for n = 2 only, whereas CF2 has been used for n = 2-8. The cage structure of the water cluster...
Stability of gold clusters: molecular-dynamics simulations Erkoç, Şakir (2000-09-01) Structural stability and energetics of gold clusters, Au, (n = 3-555), have been investigated by molecular-dynamics simulations. An empirical model potential energy function has been used in the simulations. Stable structures of the microclusters for n = 3-13 have been determined by molecular-dynamics simulation. It has been found that gold microclusters prefer to form three-dimensional compact structures. Molecular-dynamics simulations have also been performed for spherical gold clusters generated from FCC...
Molecular-dynamics simulations of silicene nanoribbons under strain Ince, Alper; Erkoç, Şakir (2012-01-01) Structural properties of silicene nanoribbons (SiNRs) of varying width have been investigated under 5% and 10% uniaxial strain via classical Molecular-Dynamics simulations at 1 and 300?K temperatures by the aid of atomistic many-body potential energy functions (PEFs). It has been found that under strain, SiNRs show such material properties: they are very ductile, with considerable toughness and a very long plastic range before fragmentation.
