A research team from IBM has managed to produce an integrated circuit on a sheet of graphene, a sheet of carbon a single molecule thick. Until now scientists have managed to fabricate discrete components such as transistors, but have struggled to find a technique that allows them to be integrated and fabricated as a wafer. Graphene, like its cousin, carbon nanotubes, exhibits fascinating electrical, optical, mechanical and thermal qualities – but finding ways to use them in commercial technology is…
