Abstract

original image

The coverage- and temperature-dependent phases of C60 film on Ru are studied using STM. The slow decomposition of C60 molecules into carbon clusters overlaps with the fast crystallization of the clusters to form graphene, giving rise to a unique graphene-on-C60 structure. With further thermal activation, the decomposition of the buried C60 molecules transforms the intercalated structure into a bilayer graphene sheet.
