And just like everything graphene, it’ll take 10 years before they can manufacture it at scale, and the cost will be outrageous. 
Still, pretty cool.
“It is chemically, mechanically and thermally robust and can be patterned and seamlessly connected to semimetallic epigraphene using conventional semiconductor fabrication techniques.”
Sounds promising.
Can someone explain the implications of the bandgap and room temperature mobility values for future chip designs?
My possibly wrong, not researched, and half remembered from college first impressions are: the band gap is lower than Silicon, so it might not be appropriate in room temperature applications/very small gate sizes due to dark current. But the mobility is very high, meaning lower voltage gates might be possible, or higher switching speed/lower latency gates.
Half the band gap of silicon, 10 times the mobility, at room temperature… sounds like it would be able to switch up to 20 times faster in the same conditions.
I can’t read the full paper, but what I’d wonder is how those values change with temperature:
0.6eV at 300K is similar to Germanium, which has slightly lower mobility but has been successfully used in semiconductors. If graphene has a better dimensional stability (as in, doesn’t grow random dendrites over time), then it could be a decent improvement.
wait, last time i’ve checked if you want fast switching, faster than silicon can get you, you use GaN, and it has 3.4eV band gap. how does it work?
F you paywall
Hmmm… Infineon has been doing work with graphene semiconductors for years. Something seems a bit off with this article.
Graphene is an amazing material. It can do anything and everything… except leave the lab.
Lmao too true
The last thing I heard that about was aerogel.
Unless I’ve missed something, nothing’s changed!
It took me about a minute to find this: graphene aerogel for sale.
I’ll say the same thing I said in another comment. It took 15+ years for “5nm” chips to be produced. China just made some last year which is a development the West thought incredibly fast.
I think most of us are ignorant to just how far behind consumer electronics are to things happening in the lab. Maybe in 15 years graphene chips will be all the rage.
As soon as we have this commercialized, fusion is just around the corner.
Quite the leap, eh?
