Structural stability and energetics of gold microclusters Aun (n=313,19–555) have been investigated by molecular-dynamics simulations. A model potential energy function has been parametrized for the gold element by using the dimer interaction potential energy profile of the Au2, which is calculated by relativistic density functional method. Stable structures of the microclusters for (n=3–13) have been determined by a 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 crystal structure with sizes (n=19–555 ).

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...
Zirconium microclusters: molecular-dynamics simulations and density functional calculations Bastug, T; Erkoç, Şakir; Hirata, M; Tachimori, S (2000-09-01) Structural stability and energetics of zirconium microclusters Zr, (n = 3-13) have been investigated by molecular-dynamics simulations and density functional calculations. A semi-empirical modelpotential energy function has been parametrized for the zirconium element by using the dimer interaction potential energy profile of Zr-2, which is calculated by the relativistic density functional method. Stable structures of the microclusters for n = 3-13 have been determined by a molecular-dynamics simulation. Rel...
Molecular-dynamics simulations of carbon nanocage structures: Nanoballs and nanotoroids Erkoç, Şakir; Vural, DC (World Scientific Pub Co Pte Lt, 2001-06-01) The structural stability of carbon nanocages, fullerens and toroids, have been investigated by performing molecular-dynamics computer simulations. The systems considered are C-120 and C-240 in ball and toroidal structures. Calculations have been realized by using an empirical many-body potential energy function for carbon. It has been found that C-120 ball is very unstable, and the other structures are relatively more strong against heat treatment.
Molecular-dynamics simulations of nickel clusters Erkoç, Şakir; Gunes, B; Gunes, P (2000-07-01) 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....
Cluster, surface and bulk properties of ZnCd binary alloys: Molecular-dynamics simulations Erkoç, Şakir (2005-01-01) The structural and electronic properties of isolated neutral Zn Cd-n clusters for m+n <= 3 have been investigated by performing density functional theory calculations at B3LYP level. The optimum geometries, vibrational frequencies, electronic structures, and the possible dissosiation channels of the clusters considered have been obtained. An empirical many-body potential energy function (PEF), which comprices two- and three-body atomic interactions, has been developed to investigate the structural features ...
