Nanocomposites with p- and n-Type Conductivity Controlled by Type and Content of Nanotubes in Thermosets for Thermoelectric Applications

Nanomaterials, 2020
In this work, composites based on epoxy resin and various carbon nanotubes (CNTs) were studied regarding their thermoelectric properties. The epoxy composites were prepared by infiltration of preformed CNT buckypapers. The influence of different types of

Huge Seebeck coefficients in nonaqueous electrolytes [PDF]

The Journal of Chemical Physics, 2011
The Seebeck coefficients of the nonaqueous electrolytes tetrabutylammonium nitrate, tetraoctylphosphonium bromide, and tetradodecylammonium nitrate in 1-octanol, 1-dodecanol, and ethylene-glycol are measured in a temperature range from T = 30 °C to T = 45 °C.

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.
