ABSTRACT: We investigated graphene
structures grafted with fullerenes. The size of the graphene sheets ranges from
6400 to 640,000 atoms. The
fullerenes (C60 and C240) are placed on top of the
graphene sheets, using different impact velocities we could distinguish three
types of impact. Furthermore, we investigated the changes of the vibrational
properties. The modified graphene planes show additional features in the
vibronic density of states.
