In this talk, we will discuss a factor that determines atomistic configuration of constituent elements based on first-principles calculation results, using group-III nitrides. To investigate the ordered phases of mixed group-III nitride ternary alloys, a first-principles based lattice model is applied to survey the atomistic configurations with the lowest formation enthalpy for a wide range of compositions.
