Decomposition and stability of group-III nitride ternary cubic spontaneously ordered alloys

Decomposition and stability of group-III nitride ternary cubic spontaneously ordered alloys

Spinodal decomposition temperatures are calculated for cubic ternary InGaN, GaAlN, InAlN, and GaAsN alloys with an arbitrary degree of CuPt-type spontaneous ordering. It is shown that ordered alloys (superstructures) are potentially more stable with respect to decomposition than random alloys.
