"It is created by etching a tiny cavity in phosphorous-doped silicon. The cavity is bordered by three electrodes: a source, a gate, and a drain. The source and drain are separated by just 150 nanometers, while the gate sits on top. Electrons are emitted from the source thanks to a voltage applied across it and the drain, while the gate controls the electron flow across the cavity. ... The new vacuum tube's inherent immunity to radiation could save the military and NASA a lot of time and money, while its faster operation makes it a rare candidate for so-called terahertz technology."
The following section of the article seems to be an isolated out of place part. I have moved it here to preserve it, as I believe it is sound. Can someone with the appropriate knowledge find a more appropriate place. A reference would be good as well.

The description of Space charge should mention Child's law, which works as long as the cathode temperature is high enough, which as far as I know is usual in vacuum tubes. Electrons come off the cathode until the field is zero, due to the space charge itself. This give the quantity perveance, a characteristic value for space charge limited emission.

No comment on hyphenating vacuum tube, but note that a high power tube is not necessarily high powered. A high power tube means that it can switch a lot of power, but it doesn't necessarily use (or dissipate) so much power itself. Gah4 (talk) 12:25, 10 February 2022 (UTC)

As for a recent edit, it does seem to me that the triode, which allows for amplification, was the beginning of actual modern electronics. Yes the thermionic diode, and also the semiconductor (point contact) Cat's whisker rectifier were earlier, but without amplification, weren't really modern electronics.
