Earlier this month, researchers from the Georgia Institute of Technology in Atlanta published a paper in Nature. The study discusses producing epigraphene from silicon carbide (SiC). Semiconducting...
Sounds pretty cool, but I can’t tell from the article what they actually did to make it semiconductive. They heat it up and then heat it up again- that makes it a semiconductor? They drive off the doping agent- somehow that’s desireable? IIRC silicon chemistries require doping agents like arsenic to produce the semiconductor effect. I don’t get it.
And of course, the actual paper is fucking paywalled.
