已经对实心溶液的冶金状态对热电功率（TEP）测量的影响，由于晶体缺陷的电子散射引起的，已经进行了充分的研究。然而，第二阶段形成对TEP的影响已被忽略，并主要在理论上讨论。在这里，我们显示了测得的TEP与两相SN/TE合金的微观结构之间的相关性。将TEP值拟合到基于Bergman-Levy和一般有效培养基方程的耦合模型中，并显示出符合下限区域的耦合模型，对应于平行的添加配置。
The influence of the metallurgical states of solid solutions on the thermoelectric power (TEP) measurements, due to electron scattering by crystalline defect, has been well studied. Yet, second phase formation influence on TEP has been neglected and was mainly discussed theoretically. Here we show a correlation between measured TEP and the microstructure of two-phase Sn/Te alloys. The TEP values were fitted to a coupled model based on the Bergman-Levy and the general effective medium equations and shown to conform to the lower bound region, corresponds to a parallel addition configuration.
