用原位微焦劳厄衍射法研究了化合物(Gete)(N)Sb(2)Te(3)(n=6，12，15)的变温相变。在~300°C，涉及阳离子缺陷有序的扩散过程导致了不同的纳米结构，这些结构与热电特性的变化有关。
Temperature dependent phase transitions of compounds (GeTe)(n)Sb(2)Te(3) (n = 6, 12, 15) have been investigated by in situ microfocus Laue diffraction. Diffusion processes involving cation defect ordering at ~300 °C lead to different nanostructures which are correlated to changes of the thermoelectric characteristics.
