New Findings On Graphene As a Conductor With IC Components

ClockEndGooner (1323377) writes Philadelphia's NPR affiliate, WHYY FM, reported today on their Newsworks program that a research team at the University of Pennsylvania have released their preliminary findings on the use of graphene as a conductor in the next generation of computer chips. From the article: "'It's very, very strong mechanically, and it is an excellent electronic material that might be used in future computer chips,' said Charlie Johnson, a professor of physics and astronomy at the University of Pennsylvania. ... Future graphene transistors, Johnson said, are likely to be only tens of atoms across."

    Except for when it comes to actually building stuff with it.

    The potential is there, obviously... but compare to how long it took to roll some up into simple tubes in an economically acceptable manner (ie, nanotubes are only just getting some actual use). I'm sure graphene as a computer component will be totally awesome -- but not until someone finds an *easy* way to build it, at most only 100X the cost of the equivalent in silicon.

      Isolation of nanotubes (1991, Iijima) preceded isolation of graphene (2004, Geim & Novoselov) by over a decade. It's likely that the first commercial applications of graphene will be exfoliated graphite used as a component in polymer composites. It's cheap and the materials prep is straightforward and scalable. Electronics quality graphene (CVD-grown or SiC-derived epitaxial) is still fairly expensive, about $10/sqcm on Cu, though the price is plummeting as the bigger players (Samsung, IBM) get involved.

    Well, that's a terrible summary. At least they linked to the actual paper.

    Good on Charlie for getting all this press out of the paper. This is continuation of work started when I worked in his lab (thin graphene transistors can be made with e-beam lithography, that gets you a bandgap and you can actually think about making a digital transistor, this paper has better measurements and better e-beam lithography - there now you don't have to read either of the papers).

    It's not clear that any of this stuff will ever be used as actual digital logic. I think it's more likely to see commercialization as an analog transistor in a sensor (reason #1 - no e-beam litho required). Someone from Charlie's group will likely be part of making active graphene electronics work out. He's got former students or postdocs at Intel and IBM, and there are at least two of us with graphene based startup companies. So, we're working on making graphene electronics something other than an academic curiosity.

      my thoughts on reading the summary was the memristors will likely be the next big generation of computer chips, with technology demonstrations in the lab and HP starting to beat the drum for their research

      just gleaning from the article it seems that they want to arrange nano tubes, split them chemically and then fold them over... and then they will do,,, something (not mentioned in the article) to make then into transistors... It would seem to leverage the same logic as transistors (unlike memristors that require a new family of logic that merges processor and memory,) which would be a big advantage for adoption, so if they can manage the manufacturing and start spitting out working units then I'll bite

      what's your take... Graphene transistors or memristors?
