Scientists Build Computer Out of Atom-Thick Material It's an important step forward in nanotube development By Kevin Spak, Newser User Posted Sep 26, 2013 7:38 AM CDT 11 comments Comments In this Dec., 2006 photomicrograph from The Nakao Hamaguchi Laboratory of the University of Tokyo, a "carbon nanotube ramen" in a bowl with diameter measuring one-thousandth of a millimeter is shown. (AP Photo/The Nakao Hamaguchi Laboratory of the University of Tokyo, HO) (Newser) – A team of Stanford scientists has built a working computer out of carbon nanotubes, a nigh-impossible feat that could herald silicon's eventual replacement. Granted, the device (which is named "Cedric," the BBC notes) isn't terribly useful, containing as many transistors as the earliest 1950s computers. But it can run a basic OS, perform calculations, and switch between processes. "It really is a computer in every sense of the word," the project's lead electrical engineer tells the Wall Street Journal . Carbon nanotubes are rolled out of sheets of pure carbon that are one atom thick. A bundle of 10,000 would be about the width of a human hair. They're extremely promising conductors, but must be grown like crystals, and tend to develop impurities. "People said you would never be able to manufacture this stuff," one Stanford engineer says. The results could extend the theoretical limits of Moore's Law (up to a point anyway), because the nanotubes have the potential to be vastly superior to silicon, CNET observes.
