  • Abstract
    A modification of the continuity equations for electrons and holes in materials with deep donors or acceptors is presented. The modification is necessary in order to prevent violation of charge conservation in transient simulations. The influence of incomplete ionization of dopants on the transient characteristics of a SiC power diode is demonstrated
