Abstract

The electronic interactions of fullerene molecules with metals, with other molecules, and with themselves are important to the chemical and conductive properties of these materials. We demonstrate high resolution scanning tunneling microscopy images of C60 molecules condensed on epitaxial gold (111) films on mica, in which the C60 molecules are isolated from each other. The C60 molecules were locked in position to the gold substrate by an ordered layer of methyl isobutyl ketone. The images of the C60 molecules exhibit intramolecular contrast indicating a significant electronic interaction with the gold substrate. Current versus voltage measurements show that both the C60 and the thin film of methyl isobutyl ketone have conductances comparable to that of the gold substrate.
