Patent ID: 8574525

Claim:
A method for growing (Al,Ga,In)N crystals, comprising: (a) placing (Al,Ga,In)N source materials and (Al,Ga,In)N seed crystals into a vessel; (b) filling the vessel with a solvent for dissolving the (Al,Ga,In)N source materials and transporting the dissolved (Al,Ga,In)N nitride source materials to the (Al,Ga,In)N seed crystals for ammonothermal growth of the (Al,Ga,In)N crystals; and (c) placing boron-containing material into the vessel's environment for use as impurity getters during the ammonothermal growth of the (Al,Ga,In)N crystals, wherein the boron-containing material includes one or more of borane (BH 3 ), diborane (B 2 H 6 ), borazane (BNH 6 ), borazine (B 3 N 3 H 6 ), sodium borohydride (NaBH 4 ), and boron in its elemental form.
