High Seebeck Coefficient BiSbTe Nanowires

Electrochemical and Solid-State Letters, 2010
Bismuth antimony telluride (BiSbTe) nanowires were electrodeposited at constant potentials into polycarbonate templates from a tartaric-nitric acid electrolyte. Optimum deposition potentials were obtained from polarization and compositional analysis. X-ray diffraction analysis showed a preferential (015) orientation for the nanowires.

ErAs/InGaAs superlattice Seebeck coefficient

ICT 2005. 24th International Conference on Thermoelectrics, 2005., 2005
InGaAs with embedded ErAs nano-particles is a promising material for thermoelectric applications. The incorporation of erbium arsenide metallic nanoparticles into the semiconductor can provide both charge carriers and create scattering centers for phonons.

A Nanoscale Standard for the Seebeck Coefficient

Nano Letters, 2011
The Seebeck coefficient, a key parameter describing a material's thermoelectric performance, is generally difficult to measure, and no intrinsic calibration standard exists. Quantum dots and single electron tunneling devices with sharp transmission resonances spaced by many kT have a material-independent Seebeck coefficient that depends only on the ...

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.

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.

Field-effect-modulated Seebeck coefficient in organic semiconductors

Nature Materials, 2008
Central to the operation of organic electronic and optoelectronic devices is the transport of charge and energy in the organic semiconductor, and to understand the nature and dynamics of charge carriers is at the focus of intense research efforts. As a basic transport property of solids, the Seebeck coefficient S provides deep insight as it is given by

Spin seebeck coefficient of a molecular spin pump

Physical Chemistry Chemical Physics, 2011
Within a generalized version of previously considered model of a molecular spin pump controlled by an external electric field [J. Fransson and M. Galperin, Phys. Rev. B, 2010, 81, 075311] we discuss thermal properties of such spintronic devices. The spin Seebeck coefficient of a molecular spin pump is introduced, and several possible definitions of a ...

Seebeck Coefficient of Thin-Film Germanium

Journal of Applied Physics, 1967
Thin films of germanium of p-type conductivity with Hall mobility values up to 350 cm2/V·sec, carrier concentrations of 1017 to 1019 cm−3, and resistivity values of 0.03 to 0.4Ω·cm were vacuum deposited. Values of Seebeck coefficient in the range from 150 to 400 μV(°C)−1 have been measured near room temperature in these films, and have been correlated ...
