    2000.04~2014.03Homogeneous InGaN films with large indium mole fraction are difficult to grow because of their compositionally unstable nature. In order to understand the compositionally unstable nature of InGaN, I carried out thermodynamic analyses and empirical interatomic potential calculations. Moreover, I investigate the influence of lattice constraint from substrates on compositionally unstable nature of the alloy..
