摘要: In one instance, the seed crystal of this invention provides a nitrogen-polar c-plane surface GaN layer supported by metallic plate. The coefficient thermal expansion plate matches that layer. is bonded to with bonding metal. metal not only bonds but also covers entire prevent corrosion and optionally spontaneous nucleation on during bulk growth in supercritical ammonia. compatible corrosive environment ammonothermal growth.
