  • Samsung promises a game changer in chip design

    Posted April 7, 2014 - 5:43 pm

    If graphene can do everything Samsung claims, silicon might fall out of favor.
  • Graphene goes 3D: No glasses necessary

    Posted February 18, 2012 - 8:51 am

    Everyone who's followed science news in the last couple years knows that graphene is the new sliced bread, but after the initial breakthrough and excitement, no one has been able to solve the riddle of current leakage. See, you have to pack transistors pretty tightly on a computer chip; each chip has to have regulated voltage in order to perform its task of being on or off. Graphene, even insulated up the wazoo, leaks its charge out, which would cook the surrounding transistors.
  • Graphene could change how we harvest solar energy

    Posted October 15, 2011 - 8:25 am

    Sparked by their recent findings, some MIT researchers have realized that shining some light on Graphene, a carbon sheet a single atom thick, can get those electrical juices flowing. Previously only possible “under very special circumstances,” the new current generating effect could pave the way for better photodetectors, night vision systems, generating electricity from sunlight, and flux capacitors*.
  • Breakthroughs bring the next two major leaps in computing power into sight

    Modelling the unimaginably complex environment of a quantum computer and figuring out how graphene to work just like silicon while still being faster, lighter and thinner make far more practical two stages of computer development that have been theoretical until now.
  • IBM shows smallest, fastest graphene processor

    Posted April 7, 2011 - 1:43 pm

    IBM on Thursday demonstrated its fastest graphene transistor, which can execute 155 billion cycles per second, which is about 50 percent faster than previous experimental transistors shown by the company's researchers.
  • Physicists Find Mass Created 'Inside' Graphene

    Posted October 27, 2010 - 1:28 pm

    Graphene: what can't it do? Those atom-thick sheets of carbon atoms packed honeycomb-shaped crystal lattices can act as zero-gap semiconductors, biodevices, transistors, and now can perhaps create mass, simply by rolling up atom-thick sheets of this material.
  • Blistering Fast Graphene Transistors May Replace Silicon

    Posted October 25, 2010 - 12:31 pm

    Graphene is hot. The recent Nobel Prize-winning research into graphene is just the tip of the iceberg; researchers around the world have been looking at ways to take advantage of graphene's structural and electrical properties. Not only is graphene the strongest material known to man, but it is has lots of potential for use in electrical devices--it's so capable that it could eventually replace silicon transistors.
  • Graphene 'Spin Computers' Could Bring Smaller Gadgets

    Posted October 18, 2010 - 12:04 pm

    As reported at physorg.com, University of California, Riverside physicists have made breakthroughs in developing graphene-based “spin computers”. A spin computer would allow for huge storage capacity using a fraction of the power consumption of current electronics. This is accomplished through polarization of electrons--the spin process actually gives each a directional orientation, up or down. A spin computer would maximize usage of this state of materials to store more data, perform faster, and generate less heat than standard electronics.
