Abstract

The zincblende InxGa1-xN, AlxGa 1-xN, and AlxIn1-xN alloys are studied by numerical analysis based on first-principles calculations. The results show that the lattice constant of the three alloys obeys the Vegard's law. For In xGa1-xN the direct band gap bowing parameter obtained with the equilibrium lattice constant is 1.890 ± 0.097 eV. For Al xGa1-xN the direct and indirect bowing parameters of 0.574 ± 0.034 eV and 0.055 ± 0.038 eV are obtained, and there is a direct-indirect crossover near x = 0.56. For AlxIn1-xN the direct and indirect bowing parameters of 3.5694 ± 0.028 eV and 0.1953 ± 0.054 eV are obtained, and there is a direct-indirect crossover near x = 0.807.
