“…An alternative situation in which the current flows transversely to both the applied magnetic field and the temperature gradient corresponds to the Nernst effect [2]. This last effect has taken a high interest in the latest time because materials with a high Nernst coefficient could be used in cryogenic refrigeration [11]. This has prompted the search for materials that present this property, highlighting among them those observed in correlated electron systems [12][13][14], conventional semimetals [15], metallic ferromagnets [16][17][18] as well as in Dirac/Weyl semi-metal materials [19].…”

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.
