Fermi function

The Fermi–Dirac distribution, which applies only to a quantum system of non-interacting fermions, is easily derived from the grand canonical ensemble. In this ensemble, the system is able to exchange energy and exchange particles with a reservoir (temperature T and chemical potential μ fixed by the reservoir). Due to the non-interacting quality, each available single-particle level (with energy level ϵ) form… WebDefine fermi. fermi synonyms, fermi pronunciation, fermi translation, English dictionary definition of fermi. n. pl. fer·mis A unit of length equal to one femtometer .

WebFrom Fermi-Dirac statistics, however, we find that average energies are on the order of the Fermi energy, which are typically about 5 eV. So the classical prediction is wrong by about two orders of magnitude. The difference is due to the fact that electrons obey the exclusion principle, and cannot all fit in the low-lying states near kT.
