Identification of a positive-Seebeck-coefficient exohedral fullerene [PDF]

open access: yesNanoscale, 2016
If fullerene-based thermoelectricity is to become a viable technology, then fullerenes exhibiting both positive and negative Seebeck coefficients are needed.

Evolution of correlation strength in KxFe(2-y)Se2 superconductor doped with S

open access: yes, 2011
We report the evolution of thermal transport properties of iron-based superconductor K$_x$Fe$_{2-y}$Se$_2$ with sulfur substitution at Se sites. Sulfur doping suppresses the superconducting $T_c$ as well as the Seebeck coefficient.

Seebeck effects in two-dimensional spin transistors [PDF]

open access: yesPhys. Rev. B 91, 075418 (2015), 2014
We consider a spin-orbit-coupled two-dimensional electron system under the influence of a thermal gradient externally applied to two attached reservoirs. We discuss the generated voltage bias (charge Seebeck effect), spin bias (spin Seebeck effect) and magnetization-dependent thermopower (magneto-Seebeck effect) in the ballistic regime of transport at ...

Non-dissipative Thermal Transport and Magnetothermal Effect for the Spin-1/2 Heisenberg Chain

open access: yes, 2004
Anomalous magnetothermal effects are discussed in the spin-1/2 Heisenberg chain. The energy current is related to one of the non-trivial conserved quantities underlying integrability and therefore both the diagonal and off diagonal dynamical correlations

Computational Seebeck coefficient measurement simulations

open access: yesJournal of Research of the National Institute of Standards and Technology, 2012
We have employed finite element analysis to develop computational Seebeck coefficient metrology simulations. This approach enables a unique exploration of multiple probe arrangements and measurement techniques within the same temporal domain. To demonstrate the usefulness of this approach, we have performed these Seebeck coefficient measurement ...

Numerical Simulations of Thermoelectric Materials for Local Seebeck Coefficient Measurements by a Heated Microprobe

open access: yesJournal of Thermal Science and Technology, 2011
This paper presents numerical simulations of thermoelectric materials for local Seebeck coefficient measurements by a heated microprobe. The Galerkin finite element method is used to solve the governing equations with boundary conditions to obtain ...

Thermomagnetic Power and Figure of Merit for Spin-1/2 Heisenberg Chain

open access: yes, 2005
Transport properties in the presence of magnetic fields are numerically studied for the spin-1/2 Heisenberg XXZ chain. The breakdown of the spin-reversal symmetry due to the magnetic field induces the magnetothermal effect.

Demonstration of electron filtering to increase the Seebeck coefficient in ErAs:InGaAs/InGaAlAs superlattices [PDF]

open access: yesarXiv, 2005
In this letter, we explore electron filtering as a technique to increase Seebeck coefficient and the thermoelectric power factor of heterostructured materials over that of the bulk. We present a theoretical model in which Seebeck coefficient and the power factor can be increased in an InGaAs based composite material.
