SUMMARY

Tunnel and Esaki diodes can be crafted in specialized facilities, typically found in university-level research labs or silicon foundries. The production of these diodes requires advanced equipment for precise doping and layering of semiconductor materials. While vintage diodes are available on auction sites, creating a bespoke batch necessitates access to high-grade fabrication tools and expertise in semiconductor physics.

PREREQUISITES
  • Understanding of semiconductor physics
  • Familiarity with silicon fabrication techniques
  • Knowledge of doping processes in semiconductor manufacturing
  • Experience with cleanroom protocols and equipment
NEXT STEPS
  • Research semiconductor fabrication facilities at universities
  • Explore advanced doping techniques for tunnel diodes
  • Learn about cleanroom standards and practices
  • Investigate the historical context and applications of Tunnel and Esaki diodes
USEFUL FOR

Electrical engineers, semiconductor researchers, and hobbyists interested in diode fabrication and semiconductor technology.

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 ??
