Definition

EN

difference between energy (ISO 80000-5: Thermodynamics) of an electron at rest at infinity and a certain energy level which is the energy of an electron in the interior of a substance

FR

différence entre l'énergie (ISO 80000-5: Thermodynamics) d'un électron au repos situé à l'infini et un certain niveau d'énergie qui est l'énergie d'un électron à l'intérieur d'une substance

Notes

EN

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

The contact potential difference between substances a and b is given by

V a − V b = ϕ a − ϕ b e

where e is the elementary charge (ISO 80000-1).

A set of energy levels, the energies of which occupy an interval practically continuously, is called an energy band.

In semi-conductors E d and E a are used for donors and acceptors, respectively.

FR

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

La différence de potentiel de contact entre les substances a et b est donnée par

V a − V b = ϕ a − ϕ b e

où e est la charge élémentaire (ISO 80000-1).

Un ensemble de niveaux d'énergie dont les énergies occupent un intervalle pratiquement continu est appelé bande d'énergie.

Dans les semi-conducteurs E d et E a sont utilisés respectivement pour les donneurs et les accepteurs.
