<p>A method and apparatus for bulk Group-Ill 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.</p> |
