    Abstract: A method for large-scale manufacturing of gallium nitride boules. 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 grown ammonothermally. The seed orientation and mounting geometry are chosen to provide efficient utilization of the seed plates and of the volume inside the autoclave or high pressure apparatus. The method is scalable up to very large volumes and is cost effective.

    Abstract: A method for growth of indium-containing nitride films is described, particularly a method for fabricating a gallium, indium, and nitrogen containing material. On a substrate having a surface region a material having a first indium-rich concentration is formed, followed by a second thickness of material having a first indium-poor concentration. Then a third thickness of material having a second indium-rich concentration is added to form a sandwiched structure which is thermally processed to cause formation of well-crystallized, relaxed material within a vicinity of a surface region of the sandwich structure.

    Abstract: A nitride crystal or wafer with a removable surface layer comprises a high quality nitride base crystal, a release layer, and a high quality epitaxial layer. The release layer has a large optical absorption coefficient at wavelengths where the base crystal is substantially transparent and may be etched under conditions where the nitride base crystal and the high quality epitaxial layer are not. The high quality epitaxial layer may be removed from the nitride base crystal by laser liftoff or by chemical etching after deposition of at least one epitaxial device layer. The nitride crystal with a removable surface layer is useful as a substrate for a light emitting diode, a laser diode, a transistor, a photodetector, a solar cell, or for photoelectrochemical water splitting for hydrogen generation.
