摘要： Regarding a base substrate, a plurality of steps are formed stepwise on the principal surface (c-face). Each step has a height difference of 10 to 40 μm, and an edge is formed parallel to an a-face of a hexagonal crystal of GaN. Meanwhile, the terrace width of each step is set at a predetermined width. The predetermined width is set in such a way that after a GaN crystal is grown on the principal surface of the base substrate, the principal surface is covered up with grain boundaries when the grown GaN crystal is observed from the surface side. The plurality of steps can be formed through, for example, dry etching, sand blasting, lasing, and dicing.

摘要： A sapphire substrate on a surface of which a thin film of gallium nitride is formed is prepared as a seed-crystal substrate and placed in a growth vessel. Gallium and sodium metals are weighed to achieve a molar ratio of 25 to 32:68 to 75 and added into the vessel. The vessel is put into a reaction vessel. An inlet pipe is connected to the reaction vessel. Nitrogen gas is introduced from a nitrogen tank through a pressure controller to fill the reaction vessel. While the internal pressure of the reaction vessel is controlled to be a predetermined nitrogen gas pressure and target temperatures are set such that the temperature of a lower heater is higher than the temperature of an upper heater, a gallium nitride crystal is grown. As a result, a group 13 nitride crystal having a large grain size and a low dislocation density is provided.
