Carbon nanotube transistors promise faster, leaner processors

The computing industry sees carbon nanotube transistors as something of a Holy Grail. They promise not just faster performance and lower power consumption than silicon, but a way to prevent the stagnation of processor technology and the death of Moore’s Law. However, their real-world speed has always lagged behind conventional technology… until now, that is. University of Wisconsin-Madison researchers have created what they say are the first carbon nanotube transistors to outpace modern silicon.
