我们已经研究了衬底上的稳定性的影响，相对于薄外延层的分解。我们表明，由衬底引起的失配应力可以强烈地相互作用的成分波动所产生的一致性应变。这种相互作用可能会导致几百度的临界温度的变化相比，预测认为，单独的一致性应变。结果被应用到允许实验确认的III-V伪二元合金。
We have examined the influence of the substrate on the stability with respect to decomposition of thin epitaxial layers. We show that the misfit stresses induced by the substrate can interact strongly with the coherency strains engendered by composition fluctuations. This interaction may lead to changes in the critical temperature of several hundred degrees as compared to predictions that consider the coherency strains alone. Results are applied to a III‐V pseudobinary alloy that permit experimental confirmation.
