Fermi energy and Fermi-Dirac integrals for zincblende-symmetry narrow-gap semiconductors with spherical energy bands

TLDR
In this article, the Fermi-Dirac integral for narrow-gap semiconductors with spherical energy bands is derived and the role of this integral towards the convergence of the expansion of the screening charge density for impurity ions is described.
Abstract
Based on an analytical approximation (recently proposed by Joyce and Dixon) for the Fermi energy of an ideal Fermi gas, an expression for the Fermi energy of zincblende-symmetry narrow-gap semiconductors with spherical energy bands is derived. A formula for the Fermi-Dirac integral for such semiconductors is given and certain properties of the integral are discussed. As an additional study, the role of this Fermi-Dirac integral towards the convergence of the expansion of the screening charge density for impurity ions in semiconductors is described.

TL;DR: In this paper, the Fermi Dirac integral is extended to cover the energy range of semiconductor lasers by the expression η=lnF+2−3/2F and by other simple differentiable approximations applicable to higher degeneracy (η≲7) or to nonparabolic bands (f≠x1/2).
