This function provides an approximation of the Fermi-Dirac integrals of different order and restricted argument ranges. The scheme requires the solution of a nonlinear equation per edge and continuity equation to calculate the edge currents. In the current formula the density-dependent diffusion enhancement factor, resulting from the generalized Einstein relation, shows up as a weighting factor. Additionally the current modifies the argument of the Bernoulli functionsapplication/pdfeng510Generalized Einstein relationgeneralized Scharfetter-Gummel schemedrift-diffusion equationsnon-Boltzmann statistic distributionsdiffusion enhancementDiscretization scheme for drift-diffusion equations with a generalized Einstein relationReport
