(Phys.org)—Although vacuum tubes were the basic components of early electronic devices, by the 1970s they were almost entirely replaced by semiconductor transistors. But in the past few years, ...

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 ...

When most people think about vacuum tubes, they picture big glass bottles glowing inside antique radios or early computers. History often treats tubes as a dead-end technology that was suddenly swept ...

Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals? The word "transitor" has become almost invisible ...

For decades, the speed of transistors has been approaching its physical limit. Now, researchers have built a new type of vacuum/air channel electron tube that completely eliminates a fatal flaw that ...

A vacuum channel transistor controls electrons at the cathode to suppress gate leakage, letting it work inside amplifiers and NAND and NOR logic gates. (Nanowerk News) A research team in China has ...

Researchers from UC San Diego are using vacuum tube technology to develop more efficient computer processors. The research could result in faster microelectronic devices and better solar panels. Their ...
