Push-Button Logic on the Nanoscale

Push-Button Logic on the Nanoscale: "(PhysOrg.com) -- Circuits that can perform logic operations at the push of a button are a dime-a-dozen these days, but a breakthrough by researchers in the USA has meant they can be smaller and simpler than ever before. Using a single material as both the button and the circuit for the first time, scientists at the Georgia Institute of Technology have created tiny logic circuits that can be used as the basis of nanometer-scale robotics and processors."
