A study on growing of bulk AlN single crystals grown having a (011) growth face of by PVT method  

Kang, Seung-Min (Department of Advanced Science and Engineering, Hanseo University)
Abstract
AlN Single Crystal were grown by PVT (Physical vapor transport) method on bulk seed. It was performed by high-frequency induction-heating coil. AlN source powder was loaded at bottom side of the carbon crucible and the crystal seed was loaded at the upper side of the crucible. The temperature conditions of the growth was varied $2000{\sim}2100^{\circ}C$ and the surrounding pressure was $1{\times}10^{-1}{\sim}200$ Torr. And the hot-zone of the heating position was controlled elaborately according to growth. The 17 mm-diameter, 7 mm-thickness AlN single crystal is obtained for about 600 hours growing. It was recognized that the growth direction of as grown crystal was R[011] by the Laue X-Ray camera measurement.
