Abstract Scope Thermomagnetic transport is unique and perplexed as it includes the interaction of electrons, holes, and phonons with external magnetic, electric, and temperature gradient fields. The magnetic field allows separation of the electrons and holes and allows decoupling of charge and heat. Thermomagnetic power generation and cooling can replace the thermoelectric ones at low temperatures (near ambient and below). Anisotropic materials with low thermal conductivity in one direction and large electrical conductivity in a perpendicular direction are ideal for thermomagnetic applications. Hence, 2D layered materials are of interest. Topological materials with large carrier mobility and bipolar conduction further show promise for thermomagnetic applications. In this talk, we discuss our recent study of several anisotropic topological materials including Bi2Te3, 2H-NbSe2, and MoTe2. We report measurements of thermoelectric properties as well as magneto-Seebeck and Nernst coefficient in these materials and explain the results using first-principles calculations as well as simplified and phenomenological models.
