Hello Forum,
I am looking at the energy levels between the n and p regions of a diode. The p-side has a conduction band that starts at a higher energy (same for the valence band).
The n-side has the valence and condution bands that are at lower energy.
The Fermi energy line is the same for both...
I don't understand what happens to the energy level of the conduction band when the diode is forward biased...
does the conduction band of the p side gets lower and the conduction band of the n-side gets higher? Why? Do they need to match?
thanks
