Scope Reveals New Physics of Graphene

Facebook X LinkedIn Email
GAITHERSBURG, Md., Sept. 8, 2010 — Using a one-of-a-kind scanning-probe microscope, an international team of researchers discovered that electrons in graphene, which comprise four quantum states, can split into different energies when exposed to extremely low temperatures and extremely high magnetic fields. The new research raises questions about the fundamental physics of graphene and reveals new effects that may make the material even more powerful than previously expected for practical applications. While graphene is a simple material — a single-atom-thick sheet of carbon atoms arranged in a honeycomb-like...Read full article

    Glossary
    electron
    A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
    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.
    lattice
    A regular spatial display of points representing, for example, the sites of atoms in a crystal.
    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.
