Default UK Scientists Make Transistor One Atom Long, 10 Atoms Wide

Bibek Paudel points out a story about the latest step forward in the development of nano-scale circuits. Researchers from the University of Manchester have created some of the smallest transistors ever, measuring only one atom by 10 atoms. The transistors are made out of graphene, which has the potential to replace silicon in the never-ending hunt for smaller computer technology. From NewScientist: "There are other kinds of prototype transistors in this size range. But they usually need supercooling using liquid gas, says Novoselov. The new graphene devices work at room temperature. Such prototypes are typically made by building one atom at a time, or wiring up individual molecules. Those approaches are complex and impractical, Novoselov says. By contrast, the graphene transistors were made in the same way that silicon devices are, by etching them out of larger pieces of material. 'That's their big advantage,' he says."
