UK researchers reveal room-temperature graphene transistor

‘Boffins at Britain’s University of Manchester have created a transistor out of an atom-thick sheet of carbon. The high-speed device is so small only one electron can pass through at once. Crucially, the transistor operates at room temperature making it potentially viable for future microprocessors.

Details of the breakthrough were announced in the science journal Nature this week. The team, led by Professor Andre Geim of the Manchester Centre for Mesoscience and Nanotechnology, built the transistor from graphene, an allotrope of carbon that essentially fits all its constituent carbon atoms into a single plane. Discovered only three years ago, graphene is highly conductive.’
