Actually, we’re not talking the kinds of vacuum tubes used in those early computers, but rather vacuum transistors: the same physical idea, just shrunk right down to miniscule dimensions.

The tubes in question are a few 1Ж29Б-В and 6Н21Б tubes, a vacuum pentode and dual triode, respectively. Add in a few diodes, and that meets the requirements for being sufficient to build a ...

The technology remains confined to the testing phase, but China has made breakthroughs in one of the biggest issues facing the concept.

Unlike the tubes of old, however, NASA's vacuum-channel transistors measure the gap between electrodes, not in millimeters but in nanometers. Making them nanoscale has a couple of key advantages.

A new Oxford study shows how physicists made light emerge from “nothing,” offering rare insight into the hidden energy of ...

Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.

The next step for the group is to scale down the vacuum tubes and explore their many applications. If their research pans out, the computers of the future may be using technology from a century ...

In today's world, vacuum tubes or radio valves seem as dead as high button shoes and buggy whips, but DARPA sees them as very much the technology of the future and is looking to develop new tube ...
