It has been reported that a 2 ″ φ self-supporting GaN substrate using a ScAlMgO4 (SAM) single crystal as a substrate can be produced with a high yield, and it is expected to be applied to GaN power devices. We have reported on 3″ φ diameter, 2 ″ φ dislocation free, and various crystal defects in the crystal. This time, we have investigated the core, striation, and growth conditions by XRT.
