Vacum! they should sound amazing! I want one to build a super custom mic pre amp, and a guitar fuzz as well! 

Really intresting etheory, thanks for sharing.

This article is so vague it doesn't show how much this technology really owes to vacuum-tube technology.
One can see the benefits of terahertz operation.
It is likely that it wets the appetite of those audiophools who dream of seeing vacuum tubes be the dominant technology again.

Here is a much better article: http://spectrum.ieee.org/semiconductors/devices/introducing-the-vacuum-transistor-a-device-made-of-nothing

I realize this is neither a vacuum tube, nor something necessarily of interest specifically to audio folk, but I couldn't find any other group I'd rather share a fantastically nerdy link with than here ;-)

It seems like its biggest contribution thus far is speed for computers, which, indirectly, kind of helps the audio industry
It could possibly also be less temperature and radiation sensitive that a standard silicon transistor, which could be a very interesting property also.

I vaguely recall seeing an article about solid state tube IC technology decades ago in a electronic design magazine, so the concept is not that new. Apparently when you make a small, sharp enough point, it doesn't take much energy for electrons to jump off.

It looks like they have made progress toward commercializing this.
