Ground-state geometry of small Ni-C clusters

Abstract

The ground-state geometry of the NiC3 and NiC4 clusters is investigated using accurate ab initio methods and compared with predictions using the tight-binding molecular-dynamics ~TBMD! method as well as the density functional theory ~DFT! based SIESTA method. The ab initio methods predict the ground-state geometry of the NiC3 cluster to have a rhomboidal… (More)
