In this work, we describe a new protocol to grow high-quality graphene by physical vapour deposition (PVD) using C60 molecules evaporated in ultra high vacuum conditions (UHV) on Cu foils substrates.
The quality of the resulting graphene layer has been assessed by the combination of complementary surface characterization techniques. Additionally, DFT calculations allow to understand the mechanisms that determine the interaction between graphene layer and the substrate. All results confirm the success of this protocol for the growth of large area uniform single layer graphene at a lower temperature than the used with the CVD method.
