The Fermi level position ________ in the energy band diagram of a p-n junction at equilibrium states.

Fermi Level in a p-n Junction at Equilibrium:

• In a p-n junction at equilibrium, the Fermi level represents the energy level at which the probability of finding an electron is 50%.
• At equilibrium, the Fermi level is constant throughout the entire structure, meaning it is aligned across both the p-type and n-type regions.
• This alignment ensures that there is no net flow of charge carriers across the junction, maintaining equilibrium.
• The energy band diagram of a p-n junction at equilibrium shows the conduction band and valence band bending near the junction, but the Fermi level remains flat and constant.
