Stanford engineers find work around for barriers to carbon nanotube computers

We've been waiting, rather patiently we might add, for carbon nanotubes to really start making a difference in our computing lives. That day has yet to pass, but researchers at Stanford are making good progress. Breakthroughs have been coming at a steady pace over the last several years, but there are still major obstacles. For one, aligning tubes end to end has proven practically impossible, and metallic carbon nanotubes (as opposed to semi conducting ones) wreak all sorts of havoc with circuits. (That wouldn't be an issue if there was a reliable way to produce only the semiconducting variety.) Rather than charge headlong into those challenges though, the Stanford team has figured out a way around modern limitations, without sacrificing much of the energy efficiency that makes carbon nanotubes so attractive. The team has found an "imperfection-immune" way of designing nanotube circuits that removes metallic contaminants and is unaffected by misaligned tubes.
