Abstract

Polymerization and depolymerization of C60 molecules are induced by charge carrier injection from a scanning tunneling microscope tip into C60 close-packed layers. These reactions are hard to be achieved at single molecular precision because of a spatial spread of injected carriers. We report that the carrier-spreading effect produces a ring-shaped distribution of C60 polymers around the carrier injection point. Formation of the polymer ring of C60 is explained by energy dissipation of spreading carriers. Therefore, the polymer ring can be recognized as a direct reflection of carrier propagation. Subsequent electron or hole injections enlarge the ring. This result shows that both electrons and holes can induce both polymerization and depolymerization of C60 molecules.
