Magneto-Seebeck coefficient and Nernst coefficient of hot and dense hadron gas [PDF]
Phys. Rev. D 102, 014030 (2020), 2020 We discuss the thermoelectric effect of hot and dense hadron gas within the framework of the hadron resonance gas model. Using the relativistic Boltzmann equation within the relaxation time approximation we estimate the Seebeck coefficient of the hot and dense hadronic medium with a gradient in temperature and baryon chemical potential.

, 2017 The Seebeck coefficient in single and bilayer graphene sheets has been observed to be modest due to the gapless characteristic of these structures. In this work, we demonstrate that this coefficient is significantly high in quasi-1D structures of bilayer

Spin-dependent Seebeck Effect in Aharonov-Bohm Rings with Rashba and Dresselhaus Spin-orbit Interactions [PDF]
, 2016 We theoretically investigate the spin-dependent Seebeck effect in an Aharonov-Bohm mesoscopic ring in the presence of both Rashba and Dresselhaus spin-orbit interactions under magnetic flux perpendicular to the ring. We apply the Green's function method to calculate the spin Seebeck coefficient employing the tight-binding Hamiltonian.

First-principles study on the origin of large thermopower in hole-doped LaRhO3 and CuRhO2
, 2008 Based on first-principles calculations, we study the origin of the large thermopower in Ni-doped LaRhO3 and Mg-doped CuRhO2. We calculate the band structure and construct the maximally localized Wannier functions from which a tight binding Hamiltonian is

Determining a hopping polarons bandwidth from its Seebeck coefficient: Measuring the disorder energy of a non-crystalline semiconductor [PDF]
Journal of Applied Physics 119, 045101 (2016), 2016 Charge carriers that execute multi-phonon hopping generally interact strongly enough with phonons to form polarons. A polarons sluggish motion is linked to slowly shifting atomic displacements that severely reduce the intrinsic width of its transport band.

Substantial local variation of the Seebeck coefficient in gold nanowires [PDF]
Nanoscale, 2017 Nanoscale structuring holds promise to improve thermoelectric properties of materials for energy conversion and photodetection. We report a study of the spatial distribution of the photothermoelectric voltage in thin-film nanowire devices fabricated from single metal.
