Tuning of Thermoelectric Properties of MoSe2 Thin Films Under Helium Ion Irradiation
Nanoscale Research Letters, 2022 Transition metal dichalcogenides have attracted renewed interest for use as thermoelectric materials owing to their tunable bandgap, moderate Seebeck coefficient, and low thermal conductivity.

Gauge to simultaneously determine the electrical conductivity, the Hall constant, and the Seebeck coefficient up to 800 °C [PDF]
Journal of Sensors and Sensor Systems, 2023 A new high temperature gauge to simultaneously determine the electrical conductivity, the Hall constant, and the Seebeck coefficient has been developed. Screen-printed heating structures on a ceramic sample holder are used to generate temperatures up to ...

Magneto-Seebeck coefficient of Fermi-liquid in three-dimensional Dirac/Weyl semimetal [PDF]
, 2022 We investigate dissipationless magneto-Seebeck effect in three-dimensional Dirac/Weyl semimetal. The Hall resistivity $\rho_{yx}$ and thermoelectric Hall coefficient $\alpha_{xy}$ exhibit plateaus at the quantum limit, where electrons occupy only the zeroth Landau level.

Theory of the effective Seebeck coefficient for photoexcited 2D materials: the case of graphene [PDF]
Phys. Rev. B 104, 125443 (2021), 2021 Thermoelectric phenomena in photoexcited graphene have been the topic of several theoretical and experimental studies because of their potential usefulness in optoelectronic applications. However, available theoretical descriptions of the thermoelectric effect in terms of the Seebeck coefficient do not take into account the role of the photoexcited ...

Seebeck coefficient in multiphase thin films [PDF]
Materials Letters, 2020 Abstract Mg-Ag-Sb thin films were deposited by magnetron sputtering using a commercial Mg1/3Ag1/3Sb1/3 target. All the films contain principally the two phases Ag3Sb and α-MgAgSb in same proportions but exhibit different microstructures. The films have the same Seebeck coefficient despite the difference of interface density and structure. Theoretical

Seebeck Coefficients in Nanoscale Junctions: Effects of Electron-vibration Scattering and Local Heating [PDF]
Phys. Rev. B 83, 041404(R) (2011), 2010 We report first-principles calculations of inelastic Seebeck coefficients in an aluminum monatomic junction. We compare the elastic and inelastic Seebeck coefficients with and without local heating. In the low temperature regime, the signature of normal modes in the profiles of the inelastic Seebeck effects is salient. The inelastic Seebeck effects are

Thermoelectric response of a hot and weakly magnetized anisotropic QCD medium [PDF]
Physical Review C 110, 015201 (2024), 2023 We have studied the Seebeck and Nernst coefficients of a weakly magnetized hot QCD medium having a weak momentum anisotropy within the kinetic theory approach. The thermal medium effects have been incorporated in the framework of a quasi-particle model where the medium dependent mass of the quark has been calculated using perturbative thermal QCD in ...

Spin-dependent Seebeck coefficients of Ni_{80}Fe_{20} and Co in nanopillar spin valves [PDF]
Phys. Rev. B 86, 024436, (2012), 2012 We have experimentally determined the spin-dependent Seebeck coefficient of permalloy (Ni_{80}Fe_{20}) and cobalt (Co) using nanopillar spin valve devices. The devices were specifically designed to completely separate heat related effects from charge related effects.
