got this out of maximum pc: According to the team of MIT researchers, graphene technology coud pave the way to remarkably fast CPUs racing along at 500 to 1000 GHz! As farfetched as it sounds, the terahertz era may be closer than you think.
First identified in 2004, graphene is a form of pure carbon made up of a one atom thick sheet of carbon atoms. tests performed at the atomic level have shown graphene to be the strongest material ever discovered, but its graphenes electrical properties that hold the most promise. while today's silicon based processors battle with heat dissapation, electrons move around much more freely on graphene, and as a result of this reduced resistance, the substance generayes comparatively little heat.
but low temps are just the beginning ultrafast graphene transistors produce much cleaner electrical signals than silicon, making the material ideal for mobile gadgets, where the technology is most likely to show up first. just dont be suprised if one day soon you look back and snicker at how fast you thought that core i7 processor was.
