MIT researchers claim that a new material called graphene that was discovered in 2004 could be used to develop computer chips with clock speed as high as 1,000GHz. Graphene is a type of pure carbon that’s only one-atom thick and has been already used by engineers to make prototype transistors and other simple devices. MIT researchers have taken one step further in their latest effort and developed a prototype frequency multiplier that can take the clock speed of a computer chip and produce an output signal that is a multiple of that frequency.
