Graphene Transistors


Technological Review reports that IBM has created graphene transistors, quite faster that silicon ones. The prototype devices are made from atom-thick sheets of carbon and operate at 100 gigahertz, meaning that they switching on and off 100 billion times each second. As a consequence they are about 10 times as fast as the speediest transistors.
