> for more than 15 years. Much longer than that. It was old news when I started grad school (1989). As for what's new: The link to extreme tech is (as usual) useless. If you hit the linked original article: http://web.mit.edu/newsoffice/2012/tiny-compound-semiconductor-transistor-could-challenge-silicons-dominance-1210.html http://web.mit.edu/newsoffice/2012/tiny-compound-semiconduct... you will find more info, but it's quite sketchy. The press-release say MOSFET, but I'd be quite surprised if they didn't really mean MODFET (oxides of III-V are a royal PITA). My guess is that this is a proof of concept for lateral 22nm devices, ie what would be state of the art litho for the silicon world. Edit: Dear mods - it would make sense to repoint the OP to my link above. Extremetech confuses the PR and does not enhance the original info.
