Graphene is often seen as the wonder material of the future. Scientists can now grow perfect graphene layers on square centimetre-sized crystals. A research team from the University of Göttingen, together with the Chemnitz University of Technology and the Physikalisch-Technische Bundesanstalt Braunschweig, has investigated the influence of the underlying crystal on the electrical resistance of graphene. Contrary to previous assumptions, the new results show that the process known as the 'proximity effect' varies considerably at a nanometre scale. The results have been published in Nature Communications.
