MOS Capacitor under very large positive or negative bias conditions

AI Thread Summary
In MOS capacitors, the band bending ceases when the silicon Fermi level reaches the conduction band during inversion or the valence band during accumulation. This phenomenon occurs because the energy levels align, preventing further bending. Participants in the discussion suggest utilizing Google and YouTube resources for additional insights on MOSCAP band diagrams. Despite the search for answers, some users express frustration at the lack of clear explanations. The conversation emphasizes the complexity of understanding MOS capacitor behavior under extreme bias conditions.

In MOSCAP, why does the band stop bending as soon as the Si Fermi level touches either the conduction band (inversion) or the valance band (accumulation)?

Don't know, but a Google search found some good hits.

If you watch this one directly on youtube, they show links for more videos on the subject by the same author. (Jordan Edmunds)

Thank you for your help. I have been searching a lot but I cannot find the answer :(
 

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...
