چکیده

-We have investigated the influence of charge on the ground state structures for small Sin (n=5-10) clusters by using the full-potential linear muffin-tin orbital molecular-dynamics (FP-LMTO-MD) method. Addition or removal of one or two electrons does not change the geometrical configurations of the small Sin (n=5-10) clusters even though they undergo some structural distortion. But the structural distortion is different for the small Si cluster with different atomic number as charge increases. The distortion arises from the electrostatic repulsion among the charged atoms, and the change of bonding characteristic for some atoms. Key-Words:silicon cluster, stable structure, ion, distortion, molecular-dynamics simulation, charge

Investigation of structural and electronic properties of small Au n Cu m (n+m≤5) nano-clusters for Oxygen adsorption

In this study, the structures, the IR spectroscopy, and the electronic properties of AunCum (n+m≤5) bimetallic clusters were studied and compared with those of pure gold and copper clusters using the generalized gradient approximation (GGA) and exchange correlation density functional theory (DFT). The study of an O2-AunCum system is important to identify the promotion effects of each of the two...

Theoretical Study of OH Adsorption on ‎PdxCu3-x (x = 0-3) Nano Clusters‎

   Adsorption of OH on the PdxCu3-x(x=0-3) small clusters is investigated by density functional theory calculations. It is found that OH adsorbs in three possible modes including on top, bridge and hollow sites while the structures where OH bridges between two atoms are the most stable structures. The Pd-Pd, Pd-Cu and Cu-Cu equilibrium distances for most of the systems...
