WHAT DOES FERMI ENERGY MEAN IN ENGLISH?

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 non-interacting 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 thermodynamic equilibrium.

Definition of Fermi energy in the English dictionary

The definition of Fermi energy in the dictionary is the level in the distribution of electron energies in a solid at which a quantum state is equally likely to be occupied or empty.
