Nanoscale vacuum transistors – way cool, but still not as pretty as a glowing 12AU6

From AAAS, news of a super tiny vacuum-tube transistor hybrid that can operate up to .46 TERAHertz (thats 460,000 megahertz or 460 gigahertz): Return of the Vacuum Tube by Jon Cartwright Peer inside an antique radio and you’ll find what look like small light bulbs. They’re actually vacuum tubes—the predecessors of the silicon transistor. Vacuum…
