Abstract
We have succeeded in the fabrication of a 2-inch dia free-standing GaN thick wafer by one-stop hydride vapor phase epitaxy using pit-induced buffer layer. High temperature grown GaN layer on the pit-induced layer was grown with numerous inverse-pyramidal pits on the surface. A thick GaN film was separated from the sapphire substrate during cooling. The X-ray rocking curves show the full width at half maximum values of 146 and 152 arcsec for (0002) and (10-12) reflections, respectively. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
