Аннотация

We present density functional calculations of AlnAu clusters for n = 1–15. The growth pattern for AlnAu (n = 1–7, 12, 14, 15) clusters is the Au atom occupying a peripheral position of Aln clusters, and the growth pattern for AlnAu (n = 8, 10 and 13) clusters is Au-substituted Aln+1 clusters. It is found that the Au atom replaces the surface atom of an Aln+1 cluster and occupies a peripheral position. In addition, the ground state structures of AlnAu clusters are more stable than pure Aln clusters. It is found that the Al13Au cluster exhibits high stability.
