NOVEL VESSEL DESIGNS AND RELATIVE PLACEMENTS OF THE SOURCE MATERIAL AND SEED CRYSTALS WITH RESPECT TO THE VESSEL FOR THE AMMONOTHERMAL GROWTH OF GROUP-III NITRIDE CRYSTALS

摘要

Reactor designs for use in ammonothermal growth of group-Ill nitride crystals envision a different relative placement of source materials and seed crystals with respect to each other, and with respect to the vessel containing a solvent. This placement results in a difference in fluid dynamical flow patterns within the vessel.
