Title: Process for large-scale ammonothermal manufacturing of gallium nitride boules

Large-scale manufacturing of gallium nitride boules using m-plane or wedge-shaped seed crystals can be accomplished using ammonothermal growth methods. Large-area single crystal seed plates are suspended in a rack, placed in a large diameter autoclave or internally-heated high pressure apparatus along with ammonia and a mineralizer, and crystals are grown ammonothermally. The orientation of the m-plane or wedge-shaped seed crystals are chosen to provide efficient utilization of the seed plates and of the volume inside the autoclave or high pressure apparatus.
