Abstract

Scanning tunneling microscopy has been used to spatially image individual fluorofullerene C₆₀F₁₈ molecules on Si(111)-7×7 surface. The images have been interpreted with the help of ab initio calculations. C₆₀F₁₈ molecules interact with the surface with F atoms pointing down, whereas a large electric dipole moment of the molecule induces strong polarization on the surface but the charge transfer is small. It has been shown that during the time of image collection, some of the F atoms migrate from fluorofullerene molecule due to F binding energy on a Si surface being nearly twice the mean value on the C₆₀ molecule.
