Breakthrough: The World’s First Carbon Nanotube Computer

It’s only got 178 transistors, but it’s an important proof-of-concept that’s poised to keep Moore’s Law right on track. The breakthrough, in which a basic computer was powered by microscopic chains of carbon atoms, means we may have finally found a viable alternative to silicon chips. » 9/25/13 12:00pm 9/25/13 12:00pm

Hitting semiconductors with a superfast electric pulse massively…


Researchers from Kyoto University have discovered a new technique that could dramatically improve the efficiency of some semiconductors. They took gallium arsenide, and blasted it with a terahertz range electric field pulse for just a picosecond, which lead to a 1,000-fold increase in exciton density. An exciton is a… » 12/22/11 8:30am 12/22/11 8:30am
