在III/V赝二元和四元固体合金的集群和调幅分解的标准进行检查。在某些三元合金和大多数四元合金中，存在团簇和相分离的化学驱动力。然而，单晶合金被证明是稳定的相干应变能固有的任何集群或spinodal分解的合金，其中晶格参数是一个功能的组合物。解析表达式推导出Ts，温度以上，没有集群或相分离应该发生。大多数III/V伪二元和四元合金在所有温度下都是稳定的。用数值方法计算旋节线等温线。给出了GaxIn 1 −x As P1−y、A1 xGa 1 − xAsySb 1 −y和GaxIn 1 −x As P1−y系统的结果。
The criteria for clustering and spinodal decomposition in III/V pseudobinary and quaternary solid alloys are examined. A chemical driving force for clustering and phase separation exists in some ternary and most quaternary alloys. However, single crystalline alloys are shown to be stabilized by the coherency strain energy inherent in any clustering or spinodal decomposition in alloys where lattice parameter is a function of composition. Analytical expressions are derived for Ts, the temperature above which no clustering or phase separation should occur. Most III/V pseudobinary and quaternary alloys are stable at all temperatures. Numerical techniques are used to calculate spinodal isotherms. Results are presented for the systems GaxIn1−x As P1−y, A1xGa1−xAsySb1−y, and GaxIn1−x As P1−y.
