The bending rigidity of graphene and inplane strain can de‐pin the graphene from a substrate when it is grown over nanosized obstacles. Using high‐temperature scanning tunneling microcopy, K. P. Loh and co‐workers have made the unique discovery that C 60 molecules absorbed on a Ru metal surface can at once act as growth precursors to graphene and suspension struts for the growing quasi‐freestanding graphene on C 60 molecules. The electronic structure of the C 60 ‐lifted graphene is distinct from that of the graphene attached to the metal substrate.
