Abstract:Geometries and electronic properties of neutral, anion, cation of Aun( n = 1-6) cluster are investigated by two methods of density functional theory (DFF) B3LYP and BPW91. All the optimal geometries calculated are planar. The binding energy, the second difference of binding energy, HOMO-LUMO gap, electron affinities (EAs), and ionization potentials (IPs) are calculated. The results show that Auo (n = 1-6) clusters are inclined to form two-dimensional structure, and odd-even oscillation effect occurs in various particles.
