"Diffusive semiconductor moment equations using Fermi-Dirac statistics";
Zeitschrift für Angewandte Mathematik und Physik,
Diffusive moment equations with an arbitrary number of moments are formally derived from the semiconductor
Boltzmann equation employing a moment method and a Chapman-Enskog expansion. The moment equations are closed
by employing a generalized Fermi-Dirac distribution function obtained from entropy maximization. The current densities
allow for a drift-diffusion-type formulation or a "symmetrized" formulation, using dual-entropy variables from nonequilibrium
thermodynamics. Furthermore, drift-diffusion and new energy-transport equations based on Fermi-Dirac statistics are
obtained and their degeneracy limit is studied.
