Moore's Law may live on, in carbon rather than silicon

Researchers at Stanford University have fashioned a functioning computer with transistors made of carbon nanotubes, instead of silicon. Finding a suitable successor to silicon in electronics has consumed scientists in recent years, as silicon-based semiconductor manufacturing approaches physical limits on its continuing miniaturization. "Of all the candidates that have been considered as a successor to silicon, carbon nanotubes remain the most promising," IBM's Supratik Guha said.
