Abstract

The interaction of magic number (C₆₀)_m–(Au)_n clusters with individual Au atoms and C₆₀molecules is investigated using scanning tunneling microscopy. The (C₆₀)_m–(Au)_n cluster supported on Au(111) has a core–shell-like structure with Au_n 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.
