ABSTRACT

A large single crystal of AlN was grown by PVT (Physical Vapor Transport) method. The AlN crystal shaped hexagonal of the diameter of about 46 mm and the thickness of 7.6 mm was grown using 33 mm seed crystal which was grown and made by ourselves. We tried to find out repeatable growth possibility for AlN crystal growth and then to evaluate the repeatability of the growth condition of the temperature of 1950~2100oC and the ambient pressure of 0.1~1 atm.
