The Fermi energy is the energy level at which electrons are most likely to be found in a material at equilibrium. It represents the energy required for an electron to jump from the lower energy level (valence band) to the higher energy level (conduction band).
Fermi energy can be calculated using the following formula:
where:
is the Fermi energy
is the initial energy level
is the band gap, which is the energy difference between the valence band and the conduction band
Fermi level is the energy level at which the Fermi energy is located. It represents the energy at which there is a higher probability of finding an electron.
The Fermi level is located between the valence band and the conduction band, and it determines the electrical conductivity of a material. Metals have a high Fermi energy due to their low band gap, which means that electrons are more easily excited to the conduction band. This allows metals to conduct electricity easily
