Bn(n=2-8)团簇结构和稳定性的密度泛函理论研究
Density functional theory study on structure and stability of Bn (n=2-8) clusters
摘要
Abstract
Density Functional Theory (DFT) with B3LYP method at 6-31G*level was used to study the geom-etries and vibrational frequencies of Bn ( n=2-8) clusters.Our results showed that most structures of Bn micro-clusters are planar forms, only a handful of three-dimensional structures are stable ground state structures. Planar configurations contain chain-like and ring-like forms.The chain-like structure is that all atoms are in same planar, and bonds of chain’ s ends are short than middle’ s.All of ring-like stable structures are n-1 atoms a-round one atom in a circle.It that the clusters of n as odd number are more stable than others is found by calcu-lating an average of the ground state binding energy of atoms and the second difference.关键词
