“…Notice that the magnitude of the Nernst coefficient S xy reaches values in the order of k B /e ∼ 86 µV/K, which is in the same order of magnitude of the one found in bulk graphene [47], graphene nanoribbons [48] and in other two-dimensional Dirac materials such as phosphorene, stanene, and germanene [46]. In normal non-magnetic metals the Nernst signal is negligibly small (∼ 10 −2 µV/K) [46].…”

We theoretically study the thermoelectric transport properties of strained HgTe in the topological insulator phase. We developed a model for the system using a Dirac Hamiltonian including the effect of strain induced by the interface between HgTe and the CdTe substrate. The conductivity tensor was explored assuming the electrons are scattered by charge impurities, while the thermopower tensor was addressed using the Mott relation. Seebeck and Nernst responses exhibit remarkable enhancements in comparison with other two-dimensional Dirac materials, such as graphene, germanane, prosphorene and stanene. The intensity of these termoeletric responses, their dependencies with the external perpendicular magnetic field and temperature are also addressed.

“…Anno et al proposed that the reduced thermal conductivity outweighs the reduced PF by introducing high defect densities, which lead a three-fold enhancement of thermoelectric value over original graphene [109]. Furthermore, Duan et al tuned the thermal transport and thermoelectric properties of graphene by using magnetic fields and obtained a ZT value as high as 2.4 under a strong magnetic field [110]. These tuning strategies can greatly facilitate the thermoelectric applications of graphene.…”

The rapid development of synthesis and fabrication techniques has opened up a research upsurge in two-dimensional material heterostructures, which have received extensive attention due to their superior physical and chemical properties. Currently, thermoelectric energy conversion is an effective means to deal with the energy crisis and increasingly serious environmental pollution. Therefore, an in-depth understanding of thermoelectric transport properties in two-dimensional heterostructures is crucial for the development of micro-nano energy devices. In this review, the recent progress of two-dimensional heterostructures for thermoelectric applications is summarized in detail. Firstly, we systematically introduce diverse theoretical simulations and experimental measurements of the thermoelectric properties of two-dimensional heterostructures. Then, the thermoelectric applications and performance regulation of several common two-dimensional materials, as well as in-plane heterostructures and van der Waals heterostructures, are also discussed. Finally, the challenges of improving the thermoelectric performance of two-dimensional heterostructures materials are summarized, and related prospects are described.
