Crafting Tunnel / Esaki Diodes: What Facilities Are Needed?

[Nik_2213]

This is not a home-work or course-work question. It is hypothetical, driven by curiosity.

Are any Tunnel / Esaki diodes being made ?
What grade of eg University facility / silicon forge would be required to craft a bespoke batch ?

Yes, I know a few Russian 'New Old Stock' diodes some-times show up on e-auction sites for eg $ 50 a pop, but what if your tale's protagonist needed a box full ??
