Fermi Dirac Distribution Formula

Equation for calculate fermi dirac distribution is,

$n_j=\frac{1}{e^{\left(\frac{{ϵ}_j-\mu }{k·T}\right)}+1}$

where,
n_j = the average number of fermions in a single-particle state j,
e = Base of the natural logarithm (2.71828182845904523536),
ϵ_j = The energy of the single-particle state,
μ = The total chemical potential,
k = Boltzmann constant (1.3806488e-23 J/K),
T = The absolute temperature
