Researchers Create First Functional Semiconductor Made From Graphene | Research
research.gatech.edu
external-link
Researchers at the Georgia Institute of Technology have created the world’s first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. Semiconductors, which are materials that conduct electricity under specific conditions, are foundational components of electronic devices. The team’s breakthrough throws open the door to a new way of doing electronics.

    Don’t mean to be a negative Nancy, but I’ll believe it when I see it.

      Is whatever he was holding in the video a good enough “it”? Or, like, a consumer product going all the way to market?

        Not quite I guess, that wafer is what’s needed for chip making but from reading the paper it looks like they were just trying to figure out how to make the band gap of the graphene just the right size. It says their next step is trying to adapt silicon chip making techniques to this new material. Terracing I guess to start?

    Crazy that it’s transparent. I wonder how thick that wafer is.

    Also awesome:

    we’re using properties of electrons that are not accessible to silicon

      If it’s a single sheet of graphene… about 1.5 angstrom thick.

          They don’t make big pieces or graphene like that. It’s made as a layer of graphene on some other material. Pure graphene flakes are tiny AFAIK.

    We’ve been studying and perfecting the art of silicon semiconductors and silicon electronics manufacturing for over 70 years now, it’ll take a while until this tech is anywhere near ready for applications. I’m not convinced you can do conventional CMOS on these things.

    However, this is really cool and I’d love to work on graphene semiconductors!
