Thoughts on the new Bizen transistors?

I saw this on the front page of AAC today; it's an article all about some new "Bizen" transistors—they're supposed to use Zener tunneling in order to be more efficient than regular transistors.

Personally, I'm not sure if I buy it. I looked around the web for a moment, and saw a few articles in publications like EE Times and Hackaday, but there are no—absolutely zilch—papers in any sort in any scientific journals, as far as I can tell; it seems like a case of science by press release—at best, it's vaporware to get more investors.

The first link is much closer to the TS's description. If really want to deliver a high peak power with a small transistor, such as the 2N3904, you can try avalanche mode.

Sorry, this does not "do" analog but it sure is fast.

Here's a link to Linear Technology's Application Note AN72: https://www.analog.com/media/en/technical-documentation/application-notes/an72f.pdf I cannot find that circuit there.

EDIT: Here's a link to an explanation of that circuit. Original source is still uncertain. Probably Jim Williams but maybe a different application note:

EDIT2: This may be it, page 93: https://www.analog.com/media/en/technical-documentation/application-notes/an47fa.pdf

If it is a new discovery then actual products are months away. And if it is an actual discovery of any value you will read more about it. Every week I read about new discoveries but I seldom see them come to market. There is a world of distance between something that can produce some results in a lab and a thing that can be mass produced with acceptable production yields.
The sad fact is that now with spell check and grammar guides any fool can produce a document that seems fairly literate. So just because it is printed does not make it even close to real.

I followed some of the links in @Comrade Pingu 's post #1 and saw this short article.

I guess the reason they seem to be only publishing vague descriptions has something to do with the (un-)patent status of the technology. Publishing prior to filing for a patent limits the amount of time they have to submit a formal application, at least in the United States.
That is true about patenting. But for scientific discoveries the verification comes from others being able to duplicate the claimed results, thus validating the published claim. I once invalidated a published claim by a consultant of ours, whose results I could not verify until I accidentally disconnected a ground in the setup and my results became identical to the consultant's results.. After that I always used the ground disconnect check to verify my results, before telling anybody anything.
