LAUSANNE, Switzerland, Feb. 7, 2011 — Smaller and more energy-efficient electronic chips could be made using molybdenite, a material developed in Switzerland. EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) published a study showing that this material has distinct advantages over traditional silicon or graphene for use in electronics applications. The study appears online in the journal Nature Nanotechnology. This is a digital model showing how molybdenite can be integrated into a transistor. (Image: EPFL) The LANES research revealed that molybdenite, or MoS2, is abundant in nature and is often used as...Read full article

    electronics
    That branch of science involved in the study and utilization of the motion, emissions and behaviors of currents of electrical energy flowing through gases, vacuums, semiconductors and conductors, not to be confused with electrics, which deals primarily with the conduction of large currents of electricity through metals.
    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.
    nanotechnology
    The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
