Aun Al( n=1~8)团簇的几何结构和稳定性
The Structure and Stability of Clusters AunAl( n=1~8)
摘要
Abstract
The structures and stabilities of AunAl(n=1~8) clusters were investigated using density functional theory at the PW91 level. By optimizing the geometric configuration of clusters, the ground-state AunAl(n=1 ~8)clusters possess two-dimensional structures for n=1~3 and three dimensional for n=4~8. The relative stabilities of the ground-state AunAl clusters were analyzed based on the averaged binding energies( Eb ) , second-order difference of energies(Δ2 E) , and HOMO-LUMO energy gaps( HLG) . The results show that Au6 Al possesses higher chemical activity and Au3 Al possesses higher stability.关键词
