氮、碳原子在X@ Al12(X=Al-,C,Si,P+)团簇吸附性质的研究
Study on the absorption properties of nitrogen and carbon atoms on X@Al12(X=Al-, C, Si, P+) clusters
摘要
Abstract
The absorption properties of nitrogen and carbon atoms on magic number clusters X@ A112(X= Al-, C, Si, P+) were investigated using density functional theory (DFT). Their structures, the Al-N and Al-C bond lengths, HOMO - LUMO gap, charges and binding energies were studied, respectively. The calculated results showed that both N and C atoms prefer to occupy the hollow site. Though X@ A112(X=A1-, C, Si, P+ ) were all stable, N and C atoms could be strongly bound on the surface of them. The absorption properties of neutral Al13 cluster were remarkably different from those of X@ A112(X=A1-, C, Si, P+) due to its unfilled electronic shell structure. The present work implied that the expected properties of the clusters could be modulated by doping the other atoms into them.关键词
