[12a-W541-5] Evaluation of III-V nitride layers grown homo-epitaxially on GaN bulks by photothermal deflection spectroscopy

Kiyotaka Fukuda1,2, Shuhei Yashiro1,2, Hajime Fujikura3, Taichiro Konno3, Takayuki Suzuki3, Tetsuji Fujimoto3, Takehiro Yoshida3, Takeyoshi Onuma2, Tomohiro Yamaguchi2, Tohru Honda2, Masatomo Sumiya1 (1.NIMS, 2.Kogakuin Univ., 3.SCIOCS)

Keywords:GaN, PDS, non-radiative recombination

III-V族窒化物材料のバンドギャップ内の深い欠陥準位を検出できる光熱偏向分光法を開発し、それを用いてGaN自立基板上とホモエピタキシャル成長した層について評価を行ったので報告する。
