CHAMPAIGN, Ill. — A new type of transistor structure, invented by scientists at the University of Illinois at Urbana-Champaign, has broken the 600 gigahertz speed barrier. The goal of a terahertz ...
In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...
The transistor laser, invented by scientists at the University of Illinois at Urbana-Champaign, has been full of surprises. Researchers recently coaxed the device to reveal fundamental properties of ...
