We 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=ā€œhttp://www.w3.org/1998/Math/MathMLā€ xmlns:xlink=ā€œhttp://www.w3.org/1999/xlinkā€&gt;+&lt;/sup> p <sup xmlns:mml=ā€œhttp://www.w3.org/1998/Math/MathMLā€ xmlns:xlink=ā€œhttp://www.w3.org/1999/xlinkā€&gt;-&lt;/sup> one-sided abrupt junctions with the acceptor density <; 10 <sup xmlns:mml=ā€œhttp://www.w3.org/1998/Math/MathMLā€ xmlns:xlink=ā€œhttp://www.w3.org/1999/xlinkā€&gt;17&lt;/sup> cm <sup xmlns:mml=ā€œhttp://www.w3.org/1998/Math/MathMLā€ xmlns:xlink=ā€œhttp://www.w3.org/1999/xlinkā€&gt;-3&lt;/sup> . The evaluated power device figure-of-merit of diamond suggests its advantage for high temperature applications.
