AI Thread Summary
Back-to-back Schottky diodes operate based on the principles of solid-state physics, particularly involving Fermi levels and band-bending. The discussion highlights a need for clarity on their operational theory, suggesting that existing knowledge may be incomplete. Participants seek reliable resources, such as webpages or textbooks, to confirm their understanding of these diodes. The conversation also touches on related devices like IMPATT and TUNNET diodes for further exploration. Comprehensive resources are essential for a deeper grasp of the theoretical underpinnings of back-to-back Schottky diodes.

I have been searching for a description of how these diodes operate. I am reasonably familiar with solid state physics and the physics of semiconductors and think I have worked out how these should work (being two back-to-back Schottky diodes) based on the Fermi levels and band-bending, but I'm not completely sure I am right. I would like to be able to confirm my impressions. Does anyone know of a webpage or electronics/physics textbook that would address the theory of their operation?
 
Engineering news on Phys.org
I would look into the availble information about IMPATT diodes and TUNNET diodes.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
