MOS Capacitor under very large positive or negative bias conditions

Click For 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 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
