{wiki=Complete_Fermi–Dirac_integral}
The Complete Fermi–Dirac integral is a mathematical function that arises in quantum statistics, particularly in the study of systems of fermions, which are particles that obey the Pauli exclusion principle. The Fermi-Dirac integral is used to describe the distribution of particles over energy states in a system at thermal equilibrium.
