| 摘要 |
The present invention provides a process for forming a bulk monocrystalline gallium nitride by using supercritical ammonia. The process comprises the steps of forming a supercritical solvent containing ion or ions of alkali metals in an autoclave; and dissolving a monocrystalline gallium nitride prepared by flux methods as a feedstock in this supercritical solvent to form a supercritical solution, and simultaneously or separately recrystallizing gallium nitride on the face of a seed.
