Abstract :
Scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) under ultra-high vacuum conditions have been used to study the initial stages of adsorption of fluorinated fullerene molecules C60F36 and C60F18 on Si(111)-7×7 surface. Spatially resolved images of individual C60F36 and C60F18 fluorofullerene molecules on Si(111)-7×7 surface have been obtained. The HOMO-LUMO gap of the adsorbed molecules has been estimated from spectroscopic measurements.
