The Coming Chip Revolution
Abstract:
At IBM, Infineon, NEC, and a clutch of startups, the leading candidate to replace silicon is the ethereal carbon nanotube.
Even though such (nanotube) transistors are still in their infancy, says IBM's Avouris, "Carbon nanotubes can get around most of the problems that doom very small silicon devices." In the lab, he has backed this statement up. It took him four years to assemble his current, third-generation prototype of a carbon nanotube transistor, but in the end, the device can carry up to 1,000 times the current of the copper wires used in today's silicon chips, making it vastly more efficient.
