Preparation and Characterization of C60/Graphene Hybrid Nanostructures Chuanhui Chen1, Adam Mills1,2, Husong Zheng1, Yanlong Li1, Chenggang Tao1 1Department of Physics, Center for Soft Matter and Biological Physics, Virginia Tech, 2Department of Physics, Princeton University Here we present a protocol for the fabrication of C60/graphene hybrid nanostructures by physical thermal evaporation. Particularly, the proper manipulation of deposition and annealing conditions allow the control over the creation of 1D and quasi 1D C60 structures on rippled graphene.

Self-assembled PCBM Bilayers on Graphene and HOPG Examined by AFM and STM Nanotechnology. May, 2018 | Pubmed ID: 29451137 In this work we report fabrication and characterization of phenyl-C61-butyric acid methyl ester (PCBM) bilayer structures on graphene and highly oriented pyrolytic graphite (HOPG). Through careful control of the PCBM solution concentration (from 0.1 to 2 mg ml) and the deposition conditions, we demonstrate that PCBM molecules self-assemble into bilayer structures on graphene and HOPG substrates. Interestingly, the PCBM bilayers are formed with two distinct heights on HOPG, but only one unique representative height on graphene. At elevated annealing temperatures, edge diffusion allows neighboring vacancies to merge into a more ordered structure. This is, to the best of our knowledge, the first experimental realization of PCBM bilayer structures on graphene. This work could provide valuable insight into fabrication of new hybrid, ordered structures for applications to organic solar cells.
