我们生长了单晶，并利用中子和X射线衍射确定了它们的超结构作为组成的函数。在很宽的温度和浓度范围内，包括稳定单一的超结构。超结构是以双空位团簇阵列为基础的，离子占据中心位置，并具有理想的浓度。根据这一超结构，讨论了该系统热电性能的测量结果。
We have grown single crystals ofand determined their superstructures as a function of composition using neutron and x-ray diffraction. Inclusion ofstabilizes a single superstructure across a wide range of temperatures and concentrations. The superstructure in thelayers is based on arrays of divacancy clusters withions occupying the central site, and it has an ideal concentration. Previous measurements of the thermoelectric properties on this system are discussed in light of this superstructure.corresponds to the maximum in thermoelectric performance of this system.
