Research Abstract

加工Si基板上への選択MOVPE法により、(0001)、(1-101)、(11-22)ならびに(11-20)面を有するAlGaN/GaN、GaN/InGaN微細ヘテロ構造を作製した。この構造は自然形成原理に従って形成されるため、表面平坦性、結晶性に優れることを明らかにした。特に、窒素を最表面とする(1-101)半極性面GaNは不純物ドーピング特性に優れ、Mgドーピングで高い正孔濃度が得られ、炭素ドーピングでもp形伝導が得られることを明らかにした。Si基板上に半極性GaN-LEDとストライプレーザ構造を作製し、光集積デバイスのためのナノへテロエピタキシの有効性を実証した
