Abstract

Abstract The influence of Ag atoms on the adsorption statuses of individual fullerene molecules on Si surface at room temperature has been investigated by scanning tunneling microscopy. For a fullerene molecule, its adsorption status can be switched from one initial state into multiple final states by attaching Ag atoms onto various parts of the molecule. Once silver atoms are removed from the adsorption sites by a STM tip, the adsorption statuses of the fullerene molecules are recovered as that for fullerene molecules on a bare Si surface.
