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…

Intel’s new revolutionary Tri-Gate 3D transistors

Intel senior fellow Mark Bohr showed off the company’s revolutionary new 3D transistors in an announcement this week in San Francisco. The power, performance, and real estate gains are impressive. Moore’s Law seems to be holding. In the video below, Bohr explains that these transistors are normally built in a two-dimensional fashion, where electrons flow…
