A method of fabricating single crystal synthetic diamond products and single crystal synthetic diamond products fabricated using said method

摘要

A single crystal CVO synthetic diamond product comprising: a flat base; a tip; sloped side walls extending between the flat base and the tip; and a thickness from the flat base to the tip of at least 1.3 mm, wherein the flat base forms a plane which lies within 20° of a {110} crystallographic plane, and wherein dislocation defects extend through the single crystal CVD synthetic diamond product in a direction from the flat base to the hp with an average direction of the dislocation defects lying within 20° of a direction perpendicular to the plane of the flat base. The diamond may contain less than 1 ppm of single substitutional nitrogen as measured by electron paramagnetic resonance.
