High-Performance Monolithic Graphene Transistors Created
MrSeb writes "Hardly a day goes by without a top-level research group announcing some kind of graphene-related breakthrough, but this one's a biggy: Researchers at the University of Erlangen-Nuremberg, Germany have created high-performance monolithic graphene transistors using a simple lithographic etching process. This could be the missing step that finally paves the way to post-silicon electronics. In theory, according to early demos from the likes of IBM and UCLA, graphene transistors should be capable of switching at speeds between 100GHz and a few terahertz. The problem is, graphene doesn't have a bandgap — it isn't a natural semiconductor, like silicon — and so it is proving very hard to build transistors out of the stuff. Until now! The researchers say that current performance "corresponds well with textbook predictions for the cutoff frequency of a metal-semiconductor field-effect transistor," but they also point out that very simple changes could increase performance 'by a factor of ~30.'"
Just because graphene might became useable does not mean it will replace silicon.
What about when we run out of sand!
I want my CP/M !! I want my "KBs" !! I want my "16 color graphics" !! I want INT 10 !! I want INT 13 !! I wany my TSRs !! I want to be graphene-free !!
I want my graphene in my pencil. I want my pencil in a small leather case along with my sliderule and my log tables.
by this time, we will have run out of carbon too..
There are at least 7 billion sources of carbon at the moment, and that's just the bipedal ones.
