[¦fer·mē di¦rak ‚dis·trə′byü·shən ‚fəŋk·shən]
(statistical mechanics)
A function specifying the probability that a member of an assembly of independent fermions, such as electrons in a semiconductor or metal, will occupy a certain energy state when thermal equilibrium exists.

FD]/[partial derivative]E) is the first derivative of the Fermi-Dirac distribution function and it is given by:
FD(s/d)] are the Fermi-Dirac distribution function corresponding to the source (s) and drain (d) electrodes, while e and h are electronic charge and Planck's constant respectively.
FD] is the Fermi-Dirac distribution function, e is the electron charge, h is Planck's constant, [phi] is the electron phase difference propagating through the upper and lower arms of the ring, and [[absolute value of [[GAMMA].
