Thermochemical nanolithography: the tip of an atomic force microscope uses heat to turn graphene oxide into reduced graphene oxide, a substance that can be used to produce nanocircuits. Image Credit: University of Illinois at Urbana-Champaign.
Today’s silicon transistors are nearly as small as allowed by the laws of physics and further miniaturization will require a different substrate. Graphene is widely regarded as the most promising candidate to replace silicon as the building block of transistors. Graphene is a carbon sheet that is a single atom thick. Electrons meet with less resistance when they travel along graphene compared to silicon so graphene nanoelectronics could be faster and consume less power than silicon.
