摘要
采用密度泛函的广义梯摩近似(GGA)下的BLYP方法,对中性Agn(n=2~12)团簇的几何结构进行了优化.结果表明:Ag2~Ag6团簇为平面结构,从Ag7团簇开始出现三维立体结构;同时发现三角形和畸变的五角双锥为中性银团簇结构的生长基础.
The first principles calculations based on density functional theory (DFT) are performed to study the geometric structure of neutral Agn clusters (n = 2 - 12). The results indicat that, neutral siliver clusters are planar structure when n ≤ 6, and three-dimension structure from Ag7 to Ag12 ,and the structure of Ag7 cluster is the base of the Ag10 ,Agn and Ag12 clusters.
