Artist's conception of a Quantum Interference Effect Transistor (QuIET). The colored spheres represent individual carbon (green), hydrogen (purple), and sulfur (yellow) atoms, while the three gold structures represent the metallic contacts. A voltage applied to the leftmost contact regulates the flow of current between the other two. (IMAGE: ACS Nano Letters)

University of Arizona physicists have discovered how to turn single molecules into working transistors. It's a breakthrough needed to make the next-generation of remarkably tiny, powerful computers that nanotechnologists dream of.
