Breakthrough Could Lead to 'Invisible' Electronics

Facebook X LinkedIn Email
EVANSTON, Ill., Dec. 27, 2006 -- Imagine a car windshield that displays a map to your destination, military goggles with targets and instructions displayed right before a soldier's eyes or a billboard that doubles as a window. These futuristic high-quality displays might be a step closer to reality now that Northwestern University researchers report that they have combined organic and inorganic materials and produced transparent, high-performance transistors that can be assembled inexpensively on both glass and plastics.A penny, seen through an array of 70 indium oxide thin film-transistors on .7 mm-thick glass,...Read full article

    Glossary
    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.
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    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...
    transistor
    An electronic device consisting of a semiconductor material, generally germanium or silicon, and used for rectification, amplification and switching. Its mode of operation utilizes transmission across the junction of the donor electrons and holes.
    transparent
    Capable of transmitting light with little absorption and no appreciable scattering or diffusion.
