Consider the following statements:
$${\text{E}}_{\text{f}}^{\text{n}}$$ and $${\text{E}}_{\text{f}}^{\text{p}}$$ are the energies of the Fermi levels on the n and p sides of p-n junction diodes, respectively. They will vary with applied as follows:
1. $${\text{E}}_{\text{f}}^{\text{n}}$$ = $${\text{E}}_{\text{f}}^{\text{p}}$$ with bias applied.
2. $${\text{E}}_{\text{f}}^{\text{n}}$$ increase and $${\text{E}}_{\text{f}}^{\text{p}}$$ decrease with forward bias.
3. $${\text{E}}_{\text{f}}^{\text{n}}$$ decrease and $${\text{E}}_{\text{f}}^{\text{p}}$$ increase with forward bias.
4. $${\text{E}}_{\text{f}}^{\text{n}}$$ increase and $${\text{E}}_{\text{f}}^{\text{p}}$$ decreases with reverse bias.
5. $${\text{E}}_{\text{f}}^{\text{n}}$$ increase and $${\text{E}}_{\text{f}}^{\text{p}}$$ decrease with reverse bias.
