It is not even the fastest. This article did well to leave out actually fast transistors, only comparing to graphene transistors which most people don't really consider fast in the first place. Checkout Indium Phosphide HEMTs (High electron mobility transistors): http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4419013 http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4419013 Mark Rodwell's group in UCSB (http://www.ece.ucsb.edu/Faculty/rodwell/rodwell_info/rodwell.html http://www.ece.ucsb.edu/Faculty/rodwell/rodwell_info/rodwell...) has been working on these transistors for a while. I think they're pushing 2 THz currently.
