Scientists at IBM have demonstrated a radio-frequency graphene transistor running at 100 GHz—that's 100 billion cycles per second—the highest frequency achieved so far for a graphene device. Although the technology is a long way from making it into computers, game consoles, or cell phones, it does start to pave the way for ever-faster chips and communications gear using carbon-based electronics—and IBM's demo was… Read More

Sixty years ago, three U.S. scientists lead by the controversial William Shockley at Bell Labs came up with the first solid state transistor. Transistors are the fundamental switches on all solid-state silicon chips: they can be switched on or off—representing the primordial zero and one. By combining transistors, the devices can be made to perform high-speed calculations. The group's goal had been to come up with a technology… Read More
