Abstract
Section titled āAbstractāWe investigate the high-field carrier transport in diamond using a full band Monte Carlo method based on ab initio calculations. The calculated breakdown field and breakdown voltage show good agreement with experimental data of n <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>+</sup> p <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>-</sup> one-sided abrupt junctions with the acceptor density <; 10 <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>17</sup> cm <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>-3</sup> . The evaluated power device figure-of-merit of diamond suggests its advantage for high temperature applications.
