All you electronics|semiconductor gurus here. Any commercially available
junctionless transistors ? Kist curious .

Well, ISTM that ideally a lateral MOSFET could be made without a junction.

Is the OP asking about native MOSFETs? Then EPADs might be a decent
approximation, some still available at Mouser/Digikey. Another option
would connecting a BC547 directly to mains to make it truly,
Sevres-certified junctionless, but something tells me it\'s not the case.

Best reagds, Piotr

The traditional way to implement transresistance without a junction is
with a triode vacuum tube. Plain old bipolar junction transistors
are the high-gain winners nowadays, and MOSFETs are the high-density
winners. What design win can a junctionless transistor achieve?
None, that I know of.

It\'s likely to remain a lab curiosity for a few more decades.

Don;t forget fluid logic gates. They have been around for over a century.

In my youth, I (unintentionally) created many
such \"junction-less\" transistors.

I did not see the value of keeping them....
