The Fermi level is the chemical potential controlling electron occupations. For an ideal Fermi gas at zero temperature it equals the Fermi energy; at nonzero temperature the chemical potential need not equal that zero-temperature energy.

The Fermi level is a crucial concept in solid-state physics, semiconductor physics, and condensed matter physics. It describes the highest energy level that electrons can occupy at absolute zero temperature. In a more general sense, the Fermi level is the chemical potential for electrons and serves as a reference point for understanding the distribution of electron energies within a material.
