Thermoelectrics (TE) is a green renewable energy technology which plays an import role in power generation due to its potential in generating electricity out of waste heat. The challenge for the development of thermoelectric is its low conversion efficiency. The efficiency of thermoelectric materials is related to the figure of merit, which is expressed as ZT = S2σT/, where S is the Seebeck coe...

Using a simplified microscopic model of coupled spin and lattice excitations in ferromagnetic insulator we evaluate the magnetic-field dependence Seebeck effect at low temperatures. The includes Heisenberg exchange coupling, harmonic potential, pseudo-dipolar interaction. Our approach goes beyond previous work [Phys. Rev. B 98, 134421 (2018)] that it does not rely on priori assumption fast equi...

Thin Film Thermoelectric Metal-Organic Framework with High Seebeck Coefficient and Low Thermal Conductivity Report Title A new thermoelectric material with high Seebeck coefficient and low thermal conductivity is demonstrated based on an electrically conducting metal–organic framework (MOF) using the guest@MOF concept. This demonstration opens a new avenue for the future development of thermoel...

Based on first-principles calculations, we study the origin of the large thermopower in Ni-doped LaRhO(3) and Mg-doped CuRhO(2). We calculate the band structure and construct the maximally localized Wannier functions from which a tight binding Hamiltonian is obtained. The Seebeck coefficient is calculated within the Boltzmann's equation approach using this effective Hamiltonian. For LaRhO(3), w...

We have employed finite element analysis to develop computational Seebeck coefficient metrology simulations. This approach enables a unique exploration of multiple probe arrangements and measurement techniques within the same temporal domain. To demonstrate the usefulness of this approach, we have performed these Seebeck coefficient measurement simulations to quantitatively explore perturbation...

We report the effects of Si substitution on the temperature-dependent electrical resistivity, Seebeck coefficient, as well as thermal conductivity in the Heusler-type compound Fe2VAl. It is found that the substitution of Si onto the Al sites causes a significant decrease in the electrical resistivity and lattice thermal conductivity. A theoretical analysis indicated that the reduction of lattic...
