Self-Assembled Nanowires

Facebook X LinkedIn Email
CHAMPAIGN, Ill., April 21, 2009 – A technique that uses self-assembled, self-aligned and defect-free nanowire channels made of gallium arsenide is being used to make transistors smaller and faster. Xiuling Li, an electrical and computer engineering professor at the University of Illinois, and graduate research assistant Seth Fortuna have made the first metal-semiconductor field-effect transistor fabricated with a self-assembled, planar gallium-arsenide nanowire channel. Nanowires are attractive building blocks for both electronics and photonics applications. Compound semiconductor nanowires, such as gallium arsenide,...Read full article

    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.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
