METHOD FOR GROWING GALLIUM NITRIDE MONOCRYSTALS Russian patent published in 2013 - IPC C30B9/12 C30B19/02 C30B29/38 

Abstract RU 2477766 C1

FIELD: electrical engineering.

SUBSTANCE: according to the method, charge stock containing a gallium source and flux components is heated and maintained at the specified temperature or, alternatively, heated and slowly cooled down from the specified temperature inside a container, with a temperature gradient maintained between the upper and the lower parts of the container under a nitrogen-containing gas pressure. The flux, by way of core components, contains cyanides or cyanamides or dicyanamides of alkaline and/or alkaline-earth metals and modifying additives enhancing gallium nitride solubility and/or increasing growth rate and/or enabling control of physical properties of crystals obtained.

EFFECT: reduced rate of corrosion of the latter, improved quality of monocrystals obtained.
