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 $1950{\sim}2100^{\circ}C$ and the ambient pressure of 0.1~1 atm.

물리기상이동법(Physical Vapor Transport(PVT) method)을 적용하여 질화알루미늄 단결정을 성장하였다. 자체적으로 성장하고 제조한 직경 33 mm 크기의 종자결정을 사용하여 직경 46 mm, 길이 7.6 mm 크기의 벌크단결정을 성장하였으며, 성장 온도는 $1950{\sim}2100^{\circ}C$, 성장 압력은 0.1~1 atm의 범위에서 조절하여 반복 성장을 통하여 성장한 결과를 보고하고자 한다.
