Plasmonic Tunneling Enables Ultrafast Circuits

Facebook X LinkedIn Email
A marriage of photonics and nanostructures could enable a huge leap in computer processing speed. A new technique using plasmonic tunneling has allowed researchers to create electrical circuits that operate at hundreds of terahertz – tens of thousands of times faster than today’s desktop computers. Assistant professor Dr. Christian A. Nijhuis of the National University of Singapore (NUS) and colleagues used two plasmonic resonators, bridged by a layer of molecules exactly one molecule thick, to create an element of a molecular electronic circuit. The layer of molecules...Read full article

    Glossary
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    tunneling
    An observed effect of the ability of certain atomic particles to pass through a barrier that they cannot pass over because of the required energy level, based on a law of quantum mechanics that predicts that the particles have a finite probability for tunneling according to their quantum-mechanical nature.
