Transition metal dichalcogenides (TMDs) are considered an advantageous alternative to their celebrated two-dimensional (2D) van der Waals akin compound, graphene, for a number of applications, especially those requiring a gapped and possibly tunable band structure. Thermoelectricity is one of the application fields where TMDs could indeed outperform graphene, thanks to their lower thermal conductivity, large effective masses, valley degeneracy, varied and tunable transport properties, as well as sensitivity of their band structures and phonon spectra to confinement. Yet, despite promising theoretical predictions, thermoelectric properties of TMDs have not been extensively investigated so far and a clear assessment of TMDs as viable thermoelectric materials, based on experimental results, is still missing. In this paper, we review the experimental findings of literature on thermoelectric properties of TMDs, to sort out the countless combinations of chemical compositions, doping, ...

过渡金属二卤化物的热电性质综述

在许多应用中，尤其是那些需要带隙且可能可调的能带结构的应用中，过渡金属二硫化碳（TMD）被认为是其著名的二维（2D）范德华类化合物石墨烯的有利替代品。热电是TMD确实可以胜过石墨烯的应用领域之一，这归因于它们的较低的导热系数，较大的有效质量，谷值简并性，变化的和可调的传输特性，以及其能带结构和声子频谱对禁闭的敏感性。然而，尽管有前景的理论预测，但迄今为止尚未对TMD的热电特性进行广泛的研究，并且仍缺乏基于实验结果对TMD作为可行的热电材料的清晰评估。在本文中，
