Researchers at the University of Stanford in the US, the Ulsan National Institute of Science and Technology (UNIST) in South Korea and Queen’s University Belfast in the UK have grown carbon-60 thin films on graphene (a sheet of carbon just one atom thick). They then made the resulting structures up into vertical transistors doped with n-type semiconducting materials and found that these devices have current on/off ratios of more than 3 x 103. The results prove that graphene is an excellent substrate for assembling small organic molecules and such heterostructures might be used in applications like high-performance detectors, solar cells and flexible transistors to name but a few……..
