HPHT growth of centimeter-sized cubic boron nitride crystals
Andrey Katrusha, Weihua Peng, Jianguo Peng +1
Single crystals of cubic boron nitride (cBN) exceeding 10 mm in size were grown by the high-pressure high-temperature (HPHT) temperature-gradient method using a Ni-Cr-based solvent…

Optical centers in cubic boron nitride and diamond: remarkable similarities
Konstantin Iakoubovskii, Andrey Katrusha, Weihua Peng +1
We present a comparative study of optical absorption and luminescence from cubic boron nitride (cBN) and diamond grown by the high-pressure high-temperature technique in the same c…

Decoration of growth sector boundaries with single nitrogen vacancy centres in as-grown single crystal HPHT synthetic diamond
Philip L. Diggle, Ulrika F. S. D'Haenens-Johansson, Ben L. Green +5
Large (> 100 mm), relatively pure (type II) and low birefringence single crystal diamond can be produced by high pressure high temperature (HPHT) synthesis. In this study we ex…
