Abstract: A method and apparatus for growing crystals in a reactor vessel, wherein the reactor vessel uses carbon fiber containing materials as a structural element to contain the materials for growing the crystals as a solid, liquid or gas within the reactor vessel, such that the reactor vessel can withstand pressures or temperatures necessary for the growth of the crystals. The carbon fiber containing materials encapsulate at least one component of the reactor vessel, wherein stresses from the encapsulated component are transferred to the carbon fiber containing materials. The carbon fiber containing materials may be wrapped around the encapsulated component one or more times sufficient to maintain a desired pressure differential between an exterior and interior of the encapsulated component.

Abstract: A method and apparatus for bulk Group-III nitride crystal growth through inductive stirring in a sodium flux growth technique. A helical electromagnetic coil is closely wound around a non-conducting cylindrical crucible containing a conductive crystal growth solution, including both precursor gallium and sodium, wherein a nitrogen-containing atmosphere can be maintained at any pressure. A seed crystal is introduced with the crystal's growth interface submerged slightly below the solution's surface. Electrical contact is made to the coil and an AC electrical field is applied at a specified frequency, in order to create eddy currents within the conductive crystal growth solution, resulting in a steady-state flux of solution impinging on the submerged crystal's growth interface.
