We have theoretically studied electric-field-domain dynamics and current self-oscillations in dc-biased negative-effective-mass (NEM) p <Superscript> + </Superscript> pp <Superscript> + </Superscript> diodes. The formation and traveling of electric-field domains in the diodes are investigated in detail with a realistic treatment of the scatterings...</superscript></superscript>
