Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

Thermoelectric (TE) effect, which enables the direct conversion of heat into electricity or vice versa, has great importance for condensed matter physics and material science due to its great potential for sustainable energy applications. Topological materials, with their topologically nontrivial band structures and rich physical phenomena, offer exciting opportunities for achieving efficient TE energy conversion. Here, an overview of the recent theoretical is provided and experimental advances at the intersection of topology and thermoelectricity. The unique features of topological materials are examined, such as band inversion, topological surface/edge states, linear Dirac/Weyl bands, and Berry curvature, affect their TE transport properties. Additionally, the potential of band topology to enhance both longitudinal and transverse TE performance is discussed. The current challenges and prospects for further advancing topological TE materials and devices are identified, aiming to develop high-performance TE materials and devices.
