The Seebeck coefficient of superionic conductors

Journal of Applied Physics, 2015
We present a theory of the anomalous Seebeck coefficient found in the superionic conductor Cu2Se. It has a phase transition at T = 400 K where the cations disorder but the anions do not. This disorder gives a temperature-dependent width to the electronic states in the conduction band. This width provides the anomalous Seebeck contribution.

Seebeck coefficients in vanadium spinels

Materials Research Bulletin, 1970
Abstract Omission of a negligibly small transport term gives a temperature-independent Seebeck coefficient for polaron charge carriers θ ± = ± 198 log [(N-p)/p], where the polaron concentration p can be determined from chemistry and the concentration N of available polaron sites is model-dependent. The expression contains no adjustable parameters.

Seebeck coefficient for the Anderson model

Physical Review B, 1997
The single-site Anderson model with degeneracy ${N}_{f}$ is solved for the case in which the lowest eigenstate contains $L$ electrons in the $f$ orbital, where $0lLl{N}_{f}.$ The noncrossing approximation is used to find the density of states including the Kondo resonance.

The Seebeck coefficients and the Fermi energies of arsenic

Solid State Communications, 1970
Abstract The Seebeck coefficient tensor components of arsenic are presented. S11 is positive: holes dominate xy plane transport; S33 is negative: electrons are the more mobile in the z-direction. A quantitative analysis, based on a two-band, multivalley Fermi surface model, is carried through. The partial Fermi energies obtained are Eef = 0.32 eV and

Anomalous Seebeck Coefficient in Boron Carbides

MRS Proceedings, 1987
ABSTRACTBoron carbides exhibit an anomalously large Seebeck coefficient with a temperature coefficient that is characteristic of polaronic hopping between inequivalent sites. The inequivalence in the sites is associated with disorder in the solid. The temperature dependence of the Seebeck coefficient for materials prepared by different techniques ...

Seebeck Coefficients of Lutetium Single Crystals

Physical Review, 1969
The Seebeck coefficients of lutetium have been measured along the [10\ifmmode\bar\else\textasciimacron\fi{}10] ($b$ axis) and [0001] ($c$ axis) crystallographic directions as a function of temperature from 8 to 300 K. These results are compared with the single-crystal Seebeck coefficients of yttrium and discussed in terms of the Fermi surface.

Resultant Seebeck coefficient formulated by combining the Thomson effect with the intrinsic Seebeck coefficient of a thermoelectric element

Energy Conversion and Management, 2009
Abstract The resultant Seebeck coefficient αR(Tz) of a thermoelectric (TE) element was derived analytically from the temperature dependence of the intrinsic Seebeck coefficient αI(Tz) by taking into account the Thomson effect, where Tz is a temperature at z along a TE element.

Thermal Conductivity and Seebeck Coefficient of InP

Physical Review, 1964
The thermal conductivity and the Seebeck coefficient of two undoped InP crystals were measured between 300 and 800\ifmmode^\circ\else\textdegree\fi{}K. Computed values of the Seebeck coefficient, assuming pure polar scattering, are in excellent agreement with the experimental data.
