Nanoribbons, Umeå University (IMAGE) Umea University Caption This is a schematic image, showing the PCBM nanoribbons, comprising four PCBM molecules organized side by side. The grey balls represent the fullerene molecules (each consist of 60 carbon atoms), and the attached side arms are characteristic for PCBM molecules. The white 'speed tracks' represent the ability for the nanoribbons to form electronic highways.
