超晶格由周期性堆叠的不同材料的交替薄层组成。可以利用界面处的晶格失配和电子势差以及由此产生的声子和电子界面散射和能带结构修改来减少声子热传导，同时维持或增强电子传输。本文重点介绍一系列以超晶格形式使用的材料，以提高热电品质因数。
Superlattices consist of alternating thin layers of different materials stacked periodically. The lattice mismatch and electronic potential differences at the interfaces and resulting phonon and electron interface scattering and band structure modifications can be exploited to reduce phonon heat conduction while maintaining or enhancing the electron transport. This article focuses on a range of materials used in superlattice form to improve the thermoelectric figure of merit.
