First graphene semiconductor was created

research.gatech.edu Researchers Create First Functional Semiconductor Made From Graphene | Research

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 founda...

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?

  Remember last year when whoever came out and said they'd made a room temperature superconductor (LK99) and than other scientists tried to recreate it and it turned out to be false?
  
  I'll believe it when it's verified by a lot of other people and not the inventor.

  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?

- I second this! Gimme the end product!

- This isn't a room-temperature semiconductor, so it's much more plausible

  Did you mean superconductor?

- Likely not scalable on an industrial level, as always.

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.

  How does he not cut himself while holding it?

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!

Carbon, so hot right now
