Hi, everyone. I'm learning basic theories about semiconductors but can't quite understand the concept of Fermi level. is this just a imaginary energy level or true existence? and why Fermi level is close to the conduction band of n-type semiconductor and valence band of p-type semiconductor? the last question is, if applying a potential on the semiconductor materials, the Fermi level will shift up and down with the increase or decrease of the voltage-why?
