Abstract

The interaction of magic number (C60)m–(Au)n clusters with individual Au atoms and C60 molecules is investigated using scanning tunneling microscopy. The (C60)m–(Au)n cluster supported on Au(111) has a core–shell-like structure with Aun forming the core, and (C60)m the protective shell. When extra C60 molecules are deposited onto the Au(111) substrate, they become attached to the outside of the (C60)m shell without altering the structure of the existing (C60)m–(Au)n cluster. When Au atoms are deposited onto the Au(111) substrate, they can move through the C60 “shell” to join the Au core leading to gross reconfiguration of the cluster.
