Graphene 'Big Mac' — One Step Closer To Microchips 50

RogerRoast writes "Scientists at the University of Manchester have come one step closer to creating the next generation of computer chips using graphene. By sandwiching two sheets of graphene with another two-dimensional material, boron nitrate, the team created the graphene 'Big Mac' – a four-layered structure which could be the key to replacing the silicon chip in computers. The research results were published in Nature Physics (abstract; full version paywalled)."

    . . . but boron nitride. I'm also worried by the fact that I knew our summary was wrong without even looking at the abstract.

    • . . . but boron nitride.

      Nobody ever likes molten Boron.

      • Nobody doesn't like molten boron!

      • Lots of people like molten boron oxide. It is the best flux that there is for brazing. Hand made bicycle frames, upmarket plumbing fixtures, a whole lot of things go together better with a little boric acid.
    • . . . but boron nitride.

      Got that? It's night-ride, you boron!

  • Someone who knows nuclear physics should comment this:

    Boron has a large cross section for neutron capture, graphite on the other hand is used as a neutron moderator. Is it possible that graphene-boron nitride is also the optimal neutron shielding material?
  • This would be the McDouble of computer chips.
  • I was expecting a new, huge Apple product in non-white colors, or some funky flavored McD's sandwich. The article was still pretty cool, though.

  • "...[A] four-layered structure"?!?


    Everyone knows a Big Mac has five layers. What they created was a McDouble. Or, if you're in California and parts of Arizona, a Double Double.

  • I'm not sure a transistor which relies on low temperature (as in, liquid nitrogen) effects to achieve an off state is actually a viable technology.

    Graphene is a wonderful material, but so far the only thing graphene is useful for is an academic research career. We (meaning nano researchers) really need to start being honest with the general media about applications. It's not ok to produce a device to measure a low temperature self-organization effect, then tell the media it's actually a prototype transist

As of next Tuesday, C will be flushed in favor of COBOL. Please update your programs.
