Chin Kyo Kim, Jae Hyung Yi: Method for fabricating GaN substrate. LG Electronics, Fleshner & Kim, April 3, 2001: US06211089 (48 worldwide citation)

Disclosed is a method for fabricating a smoothly surfaced GaN substrate. A GaN substrate is polished with diamond slurries and then, with boron carbide plates. The irreversible damaged layer which is caused by the mechanical polishing is removed by reactive ion etching, after which the GaN substrate ...
