| 摘 要： | 用相对论有效原子实势(RECP)和密度泛函(B3LYP)理论,选择LANL2DZ基组研究了AunY(n=1-5)团簇的各种几何结构及稳定性.结果表明AuY、Au2Y和Au3Y团簇的基态几何构型是平面结构,Au4Y和Au5Y的基态构型是三维结构.通过计算原子平均结合能、二阶差分能量、破碎能量及能级间隙判断AunY(n=1...

| Abstract: | The density functional method with relativistic effective core potentials(RECP) and LANL2DZ basis set are used to investigate the possible stable geometrical configurations and relative stabilities of the lowest-lying isomers of Y-doped gold clusters,AunY(n=1-5).The results indicate that the ground-state structures of AuY,Au2Y and Au3Y clusters are planar form,and they are 3D form for Au4Y and Au5Y clusters.The stability trend for the ground-state structures of AunY(n = 1-5) clusters is analyzed in terms of... |
