S&M911 Research Paper of Special Issue https://doi.org/10.18494/SAM.2013.844 Published: March 28, 2013 Growth and Evaluation of Bulk GaN Crystals Grown on a Point Seed Crystal by Ba-Added Na Flux Method [PDF] Hiroki Imabayashi, Kosuke Murakami, Daisuke Matsuo, Yuma Todoroki, Hideo Takazawa, Akira Kitamoto, Mihoko Maruyama, Mamoru Imade, Masashi Yoshimura and Yusuke Mori (Received November 26, 2012; Accepted February 12, 2013) Keywords: GaN wafer, bulk single crystal, crystal growth, point seed, Na flux method
We grew bulk gallium nitride (GaN) single crystals on a point seed by using the Ba-added Na flux method and evaluated their structural and optical properties. As a result, we successfully grew habit-controlled single GaN crystals. The size of the largest crystal in this study was 7 mm along the [0001] direction and 9 mm along the ⟨11-20⟩ direction after 200 h of growth. The cathodoluminescence (CL) images of (10-10) GaN wafers sliced from the grown crystal revealed that large areas of the wafer were dislocation free. Full widths at half maximum (FWHMs) of the X-ray rocking curve (XRC) of GaN (10-10) at low-dislocation-density sectors were from 32 to 61 arcsec. No green and yellow luminescence (GL and YL, respectively) peaks were detected from the room-temperature photoluminescence spectrum. From these results, it is found that the Ba-added Na flux method of GaN crystal growth on a point seed opens the possibility of fabricating high-quality prismatic GaN bulk single crystals.
