"Right now, you could make a processor that would be as fast as silicon but use one-tenth of the power."

'Quantum well' transistor promises lean computing
Will Knight/New Scientist Original Article

A transistor that uses one-tenth of the energy of existing components could lead to more powerful, less power-hungry computers within the next decade. Researchers at US microchip company Intel and UK research firm Qinetiq developed the transistor using a novel semiconducting material - indium antimonide.
