One of the topics we've covered multiple times at ExtremeTech is the difficulty of continuing to scale semiconductor technology, and the related problem of improving chip performance without ...
When most people think about vacuum tubes, they picture big glass bottles glowing inside antique radios or early computers.
Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified ...
A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...
A new type of transistor is being developed by scientists at the NASA Ames Research Center that meshes together the best aspect of semiconductors and traditional vacuum-tube technology. This ...
