Effect of phonon-boundary scattering on phonon-drag factor in Seebeck coefficient of Si wire
AIP Advances, 2020 For highly efficient thermoelectric devices with Si nanostructures, we have fabricated and characterized micro/nanometer-scaled Si wires preserving the phonon-drag effect in order to observe the impact of phonon-boundary scattering on the phonon-drag ...

Seebeck Coefficient of Kondo Insulators [PDF]
Journal of the Physical Society of Japan, 2002 Seebeck coefficient S of the Kondo insulators is investigated theoretically within the framework of the dynamical mean field theory. It is found that the temperature dependence changes from the ordinary behavior S ( T ) ∝ T -1 in semiconductors to approximately S ∝ T at low temperatures due to the finite imaginary part of the electron self-energy in ...

Seebeck coefficient of heavy fermion compounds
Journal of Magnetism and Magnetic Materials, 1987 The thermoelectric power (TEP) of the magnetically ordered Kondo lattices CeCu2Ge2, CeCu4Al8 and CePb3 was measured up to 350 K and compared with that of heavy-fermion UBe13. New low-T TEP-anomalies, presumably coherence-derived, are found to show up in CePb3 and UBe13, but to be absent in U0.97Th0.03Be13.

Effective modelling of the Seebeck coefficient of Fe 2 VAl [PDF]
Journal of Physics: Condensed Matter, 2019 Abstract Previous first-principles calculations have failed to reproduce many of the key thermoelectric features of Fe 2 VAl, e.g. the maximum values of the Seebeck coefficient S and its asymmetry with respect to the chemical potential.

High thermoelectric figure of merit by resonant dopant in half-Heusler alloys
AIP Advances, 2017 Half-Heusler alloys have been one of the benchmark high temperature thermoelectric materials owing to their thermal stability and promising figure of merit ZT. Simonson et al. early showed that small amounts of vanadium doped in Hf0.75Zr0.25NiSn enhanced

Seebeck coefficient of one electron [PDF]
Journal of Applied Physics, 2014 The Seebeck coefficient of one electron, driven thermally into a semiconductor single-electron box, is investigated theoretically. With a finite temperature difference ΔT between the source and charging island, a single electron can charge the island in equilibrium, directly generating a Seebeck effect.
