Abstract:
1. A process for growing a crystalline gallium-containing nitride, the process comprising: providing a high pressure apparatus; providing a capsule comprising gallium-containing feedstock in one zone and at least one seed in another zone; while maintaining an elevated pressure within the capsule, introducing a solvent capable of forming a supercritical fluid into at least the one zone and the other zone; placing the capsule within the high pressure apparatus; 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.
