Graphene Clears Major Fabrication Hurdle

Facebook X LinkedIn Email
BERKELEY, Calif., April 13, 2010 — Graphene, the two-dimensional crystalline form of carbon, is a potential superstar for the electronics industry. With freakishly mobile electrons that can blaze through the material at nearly the speed of light – 100 times faster than electrons can move through silicon – graphene could be used to make superfast transistors or computer memory chips. Graphene's unique "chicken wire" atomic structure exhibits incredible flexibility and mechanical strength, as well as unusual optical properties that could open a number of promising doors in both the electronics and the photonics...Read full article

    dewetting
    Dewetting is a phenomenon in materials science and physics where a thin film or coating spontaneously undergoes a process of breaking up and forming isolated droplets on a substrate. This occurs due to the reduction of intermolecular forces or other factors that lead to a loss of film stability. Dewetting can happen in various materials, including polymers, metals, and liquids, and it is influenced by factors such as temperature, surface energy, and the nature of the substrate. The dewetting...
    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...
    scanning electron microscopy
    Scanning electron microscopy (SEM) is an advanced imaging technique used in microscopy to obtain high-resolution, three-dimensional images of the surfaces of solid specimens. SEM achieves this by using a focused beam of electrons to scan the specimen's surface, resulting in detailed images with magnifications ranging from about 10x to 100,000x or higher. Key features and principles of scanning electron microscopy include: Electron beam: SEM uses an electron beam instead of visible light for...
