Adsorption of individual C60 molecules on Si(111).

Scanning tunneling microscopy (STM) and spectroscopy studies have been conducted for individual C 60 molecules adsorbed on SI(111)-7×7 surfaces. C 60 molecules appear to be immobilized following condensation at 300 K. Bias-dependent STM imaging and current-imaging tunneling spectroscopy data illustrate different Ci6 0 bonding configurations
