• Resumen

  • A one‐dimensional finite difference scheme adapted to high order moment equation models arising in the approximate description of semiconducting submicron structures is presented. The new scheme is a natural extension of the Scharfetter‐Gummel scheme used in drift‐diffusion models. Through local analytic solutions an accurate representation of exponentially varying solution components is realised.
