Abstract:
1. A process for growing a crystalline gallium-containing nitride, the process comprising: providing a high pressure apparatus comprising gallium-containing feedstock in one zone, at least one seed in another zone, an azide mineralizer, and at least one metal, the azide mineralizer and the metal being provided in a predetermined ratio such that nitrogen generated by decomposition of the azide mineralizer and hydrogen generated by reaction of the metal with a supercritical fluid are in a ratio of approximately 1:3; processing one or more portions of the gallium-containing feedstock in the supercritical fluid to provide a supercritical solution comprising at least gallium containing species at a first temperature; and growing crystalline gallium-containing nitride material from the supercritical solution on the seed at a second temperature, the second temperature being characterized to cause the gallium containing species to form the crystalline gallium containing nitride material on the seed.
