Inventor: WU HONGLEI
IPC: C30B23/00
Filed: 2018-09-07
Abstract: Disclosed are a crucible apparatus and a method for preparing an aluminum nitride crystal. The crucible apparatus includes a first crucible, a second crucible and a connecting tube, wherein an interior of the first crucible is in communication with an interior of the second crucible through the connecting tube, the first crucible is for containing an aluminum nitride source and the second crucible is for containing a gallium source, and the connecting tube extends into the interior of the first crucible for a length that is greater than a thickness of the aluminum nitride source contained in the first crucible. Gallium vapor generated from the gallium source in the second crucible can enter a reaction chamber of the first crucible. The gallium vapor can alter a crystallization property of the aluminum nitride crystal, which aids in controlling nucleation and diameter growth of the aluminum nitride crystal. Therefore, doping of gallium vapor into the reaction chamber of the first crucible during preparation of the aluminum nitride crystal can effectively reduce nucleation density of the aluminum nitride crystal, and also increase the dimensions of the aluminum nitride crystals, thus obtaining a large-sized aluminum nitride single crystal.
