Commercially available jumctionless transistor

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.

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.... regards, RS
