Ca掺杂Si团簇的几何结构和电子性质的密度泛函理论研究
Theoretical study on the geometric structures and electronic properties of Ca doped Si clusters by density functional theory
摘要
Abstract
The geometric structures and electronic properties of CaSin(n=1 -10)were studied by using the B3LYP method of the density functional theory(DFT)at the 6-311G +(d,p)level.And the lowest energy structures of the CaSin(n=1-10)clusters with various sizes were obtained.The results show that the lowest en-ergy structures of the silicon clusters doped with one Ca atom can exist stably, and n=2, 5 and 9 are magic numbers.关键词
