摘要
采用密度泛函理论的B3LYP方法,优化了AlmWn(m+n=2-6)团簇的稳定结构,计算了团簇的电离势,电子亲和能,最高占据轨道能级(HUMO)和最低空轨道能级(LUMO)及二者间的能隙。得出了团簇均为空间立体结构,Al4W2团簇较其他团簇的稳定的结论。
The equilibrium geometries of AlmWn(m+n=2-6) clusters are optimized by means of density functional theory(DFT).The ionization potentials(IPs),the electron affinities(EAs),the HUMO-LUMO gaps are investigated.The results show that AlmWn(m+n=2-6) clusters are three-dimensional geometry,and Al4W2 cluster is more stable than the other clusters.
