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.
I agree that it should be verified, but given that it was published on Nature gives hope that it will be reproducible.
Nature retracts controversial superconductivity paper by embattled physicist
(not LK99, but they’re not infallible).
Let’s wait until we see peer confirmation.
Also given that it’s from GA Tech, I’d expect it to be credible.
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!
Likely not scalable on an industrial level, as always.

Did you mean superconductor?
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?
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!
Give it time someone will have it running doom
