Nanotubes Make Tiny Diodes.
Scientists have made another step toward the miniaturization of electronic devices. In today's Nature, they show that a single nanotube--a microscopic pipe made of carbon--can act as a diode, a standard electronic component that allows current to pass in one direction but not the other. http://www.apnet.com/inscight/11181999/grapha.htm
