热电材料将热能直接转化为电能，在提供全球可持续能源方面发挥着重要作用。近年来，人们利用各种现代合成方法努力提高热电效率。高压合成方法具有多种优点，例如在环境压力下可以合成具有不可能结构和成分的新材料。在这篇综述中，我们将重点利用高压装置探索新的化合物。讨论了高压合成和热电测量技术。此外，还将讨论高温高压下的原位x射线衍射实验，以确定高压合成的条件。最后，对几种高压下制备的化合物（角钼矿和硅化镁）的热电性能进行了综述。
Thermoelectric materials, which convert heat energy directly into electricity, play an important role in providing globally sustainable energy. In recent years, much effort has been exerted in improving thermoelectric efficiency using various modern synthesis methods. The high-pressure synthesis method has various advantages such as the possibility of synthesizing new materials with impossible structures and compositions at ambient pressure. In this review, we will focus on exploring new compounds using a high-pressure apparatus. The high-pressure synthesis and thermoelectric measurement technique will be discussed. In addition, in-situ X-ray diffraction experiments under high temperature and high pressure to determine the conditions for high-pressure synthesis will be discussed. Finally, the thermoelectric properties of several compounds (skutterudites and magnesium silicide) prepared under high pressure will be reviewed.
