▎ 摘  要

The capability of scanning tunneling microscopy to image individual molecules intercalated under graphene is demonstrated for fullerenes. The C-60 molecules become visible through the graphene carpet grown on Ni(111) due to an extremely strong bias-dependent spectroscopic contrast. Its origin is the blocking of the chemical interaction between graphene and its substrate by the fullerenes.
