热电:从纵向到横向

Thermoelectrics: from Longitudinal to Transverse

Ken-ichi Uchida, Joseph P. Heremans

摘要:

在这篇文章中,我们展示了横向热电发电的基本原理和最新进展,在横向热电发电中,在垂直于所施加的温度梯度的方向上产生热电势。横向温差发电是凝聚态物理的核心课题之一,是解决温差发电器中接触电阻长期存在的技术难题的突破性途径。本文综述了目前已知的六种驱动机制:普通能斯特效应、反常能斯特效应、角极材料、自旋Seebeck效应、Seebeck驱动的横向热电产生和($p \times n$)型多层膜。本文总结了这些横向热电效应的原理和功能,并讨论了它们作为“未来能源”的潜力。

英文摘要:

In this article, we show fundamentals and recent advances on the transverse thermoelectric generation, in which a thermopower is generated in the direction perpendicular to an applied temperature gradient. Transverse thermoelectric generation is one of the central topics in condensed matter physics, and can be a breakthrough approach to solve long-standing technological problems with contact resistances in thermoelectric generators. We review here the six currently known driving mechanisms: the ordinary Nernst effect, the anomalous Nernst effect, goniopolar materials, the spin Seebeck effect, Seebeck-driven transverse thermoelectric generation, and ($p \times n$)-type multilayers. This article summarizes the principles and functionalities of these transverse thermoelectric effects and discusses their potential as "Future energy".
