Fermi energy
The Fermi energy is a concept in quantum mechanics usually referring to the energy difference between the highest and lowest occupied single-particle states, in a quantum system of fermions at absolute zero temperature. In a Fermi gas the lowest occupied state is taken to have zero kinetic energy, whereas in a metal the lowest occupied state is typically taken to mean the bottom of the conduction band. Confusingly, the term "Fermi energy" is often used to refer to a different but closely related concept, the Fermi level. There are a few key differences between the Fermi level and Fermi energy, at least as they are used in this article: ⁕The Fermi energy is only defined at absolute zero, while the Fermi level is defined for any temperature. ⁕The Fermi energy is an energy difference, whereas the Fermi level is a total energy level including kinetic energy and potential energy. ⁕The Fermi energy can only be defined for non-interacting fermions, whereas the Fermi level remains well defined even in complex interacting systems, at equilibrium.
