密度泛函理论对AunSc3(n=1-7)团簇结构和性质的研究
Density functional theory study on the structure and electronic properties of Aun Sc3 (n = 1-7) clusters
摘要
Abstract
Geometric structures of AunSc3 ( n = 1-7 ) clusters are optimized by using the generalized gradient approximation (GGA) density functional theory. Energy, vibrational frequency and electronic properties have been calculated. The 3 D structure of Aun Sc appears earlier than that of Aun. The triangle bipyramid structure of Au2Sc3 is a building block for larger AunSc3 of n ≤ 7. Furthermore, the investigation on the second-order difference shows that the clusters with even Au atoms have enhanced stabilities, which may be due to the electron shell effects.关键词
