Paper Abstract

SCAATTM has been developed as a novel ammonothermal method which enables to obtain strain free, high quality and large size bulk gallium nitride (GaN) crystals under high pressure and high temperature super-critical ammonia. One of the unique features of this technique is relatively high growth rate of more than a few hundred micrometers per day toward polar and non-polar axis with excellent crystalline quality. The morphology, X-ray rocking curve, etch pit density and electric properties are presented.
