Seebeck coefficient of thermoelectric moleculat junction: First-principles calculations

open access: yes, 2009
A first-principles approach is presented for the thermoelectricity in molecular junctions formed by a single molecule contact. The study investigates the Seebeck coefficient considering the source-drain electrodes with distinct temperatures and chemical ...

Seebeck coefficient of heavy fermion compounds

open access: yesJournal 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]

open access: yesJournal 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.

Calculation of Optical Conductivity, Resistivity and Thermopower of Filled Skutterudite CeRu$_4$Sb$_{12}$ based on a Realistic Tight-binding Model with Strong Correlation [PDF]

open access: yes, 2005
The filled-skutterudite compound CeRu$_4$Sb$_{12}$ shows a pseudo-gap structure in the optical conductivity spectra similar to the Kondo insulators, but metallic behavior below 80 K. The resistivity shows a large peak at 80 K, and the Seebeck coefficient

Characterization of Lorenz number with Seebeck coefficient measurement

open access: yesAPL Materials, 2015
In analyzing zT improvements due to lattice thermal conductivity (κL) reduction, electrical conductivity (σ) and total thermal conductivity (κTotal) are often used to estimate the electronic

Significant Phonon Drag Enables High Power Factor in the AlGaN/GaN Two-Dimensional Electron Gas [PDF]

open access: yes, 2019
In typical thermoelectric energy harvesters and sensors, the Seebeck effect is caused by diffusion of electrons or holes in a temperature gradient. However, the Seebeck effect can also have a phonon drag component, due to momentum exchange between charge
