Abstract

Monte Carlo calculations of the electron drift velocity in polycrystalline diamond are presented based on a formulation that includes grain boundary scattering. Our results indicate field dependent reductions of the drift velocity in polycrystalline diamond. The grain boundaries are predicted to have negligible effect on the drift velocity at high fields exceeding 70 kV/cm. However, significant drift velocity decreases are predicted at fields below 1 kV/cm, and at low temperatures This trend is in keeping with experimental mobility data that is becoming available from pulsed excitation measurements.
