Abstract :
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
