Definition

in a metal, highest occupied energy level at zero thermodynamic temperature (ISO 80000-5: Thermodynamics), where energy level means the energy (ISO 80000-5: Thermodynamics) of an electron in the interior of a substance

Notes

The term "energy level" is often used for the state of the electron, not only for its energy.

At $T = 0 unitsml(K)$ , $E_{F}$ is equal to the chemical potential per electron.

In condensed matter physics, the reference level for the energy is sometimes chosen so that, for instance, $E_{F} = 0$ .

Le terme « niveau d'énergie » est souvent utilisé pour l'état de l'électron, et pas seulement pour son énergie.

À $T = 0 unitsml(K)$ , $E_{F}$ est égal au potentiel chimique par électron.

En physique de la matière condensée, le niveau de référence pour l'énergie est parfois choisi de sorte que, par exemple, $E_{F} = 0$ .
