Engineers build computer of one-atom-thick carbon tubes

BREAKTHROUGH: Researchers took a big step in the quest for faster, ever-smaller electronic devices with a computer made of microscopic carbon nanotubes. - AFPrelaxnews 2013

While performing only basic functions at speeds likened to a 1950s computer, the tiny machine was hailed as a breakthrough in the search for an alternative to silicon transistors, which control the electricity flow in computer microchips.

Carbon nanotubes (CNTs) are rolled-up, single-layer sheets of carbon atoms - tens of thousands can fit into the width of a single human hair.
