    Asking a study question in a snap - just take a pic. If the system is exposed to changing electromagnetic fields as in capacitors , inductors , and transformers. Under illumination from a light-source with a different temperature, such as the sun as in solar cells , When the temperature is not constant within the device as in thermocouples , When the device has been altered, but has not had enough time to re-equilibrate as in piezoelectric or pyroelectric substances.

    In some situations, such as immediately after a material experiences a high-energy laser pulse, the electron distribution cannot be described by any thermal distribution. One cannot define the quasi-Fermi level or quasi-temperature in this case; the electrons are simply said to be non-thermalized.

    Terminology problems[ edit ] The term, Fermi level, is mainly used in discussing the solid state physics of electrons in semiconductors , and a precise usage of this term is necessary to describe band diagrams in devices comprising different materials with different levels of doping. In fact, thermodynamic equilibrium guarantees that the Fermi level in a conductor is always fixed to be exactly equal to the Fermi level of the electrodes; only the band structure not the Fermi level can be changed by doping or the field effect see also band diagram.

    A similar ambiguity exists between the terms, chemical potential and electrochemical potential. It is also important to note that Fermi level is not necessarily the same thing as Fermi energy.

    In the wider context of quantum mechanics, the term Fermi energy usually refers to the maximum kinetic energy of a fermion in an idealized non-interacting, disorder free, zero temperature Fermi gas. This concept is very theoretical there is no such thing as a non-interacting Fermi gas, and zero temperature is impossible to achieve. However, it finds some use in approximately describing white dwarfs , neutron stars , atomic nuclei , and electrons in a metal. On the other hand, in the fields of semiconductor physics and engineering, Fermi energy often is used to refer to the Fermi level described in this article.

    Observable phenomena only depend on energy differences. When comparing distinct bodies, however, it is important that they all be consistent in their choice of the location of zero energy, or else nonsensical results will be obtained.

    It can therefore be helpful to explicitly name a common point to ensure that different components are in agreement. On the other hand, if a reference point is inherently ambiguous such as "the vacuum", see below it will instead cause more problems.

    A practical and well-justified choice of common point is a bulky, physical conductor, such as the electrical ground or earth. It provides a reservoir of charge, so that large numbers of electrons may be added or removed without incurring charging effects.
