IBM has created graphene transistors that leave silicon ones in the dust. The prototype devices, made from atom-thick sheets of carbon, operate at 100 gigahertz — meaning they can switch on and off 100 billion times each second, about 10 times as fast as the speediest silicon transistors. Ultimately, graphene has the potential to replace silicon in high-speed computer processors.
