Adsorption of individual C60molecules on Si(111)

Scanning tunneling microscopy (STM) and spectroscopy studies have been conducted for individual C${}_6$ ${}_0$ molecules adsorbed on Si(111)-7×7 surfaces. C${}_6$ ${}_0$ molecules appear to be immobilized following condensation at 300 K. Bias-dependent STM imaging and current-imaging tunneling spectroscopy data illustrate different C${}_6$ ${}_0$ bonding configurations.
