For the both growth methods, the calculation results suggest that a compositionally unstable region is found at the InN-rich region for InGaN on GaN at higher temperatures while that for InGaN on InN can be seen at GaN-rich region due to the lattice constraint from the substrate. In case of the MOVPE, it is found that growth region of InGaN in the diagram related to V/III ratio and solid composition shrinks with increase of V/III ratio (increase of input partial pressure of NH_3). This is because the H_2 partial pressure produced by the decomposition of NH_3 increase at high V/III ratio (at high input partial pressure of NH_3).}, pages = {104--110}, title = {InGaN気相成長における気相-固相関係に対する基板拘束の影響(<小特集>ナノ構造・エピ成長分科会特集「窒化物半導体エピタキシャル成長における基板の役割」の再考)}, volume = {30}, year = {2003} }
