Graphene is a super-conductive form of carbon that is made from single-atom-thick sheets.  Recognized as the thinnest material in the world, as well as one of the strongest and hardest, it is a superior alternative to silicon with many uses. His research on mesoscopic physics and superconductivity is also very promising.
