Thermoelectric Properties of a Family of Benzodifuranone‐Based Conjugated Copolymers in Oriented Thin Films Doped Sequentially With NDMBI‐H

Advanced Electronic Materials, EarlyView.
Combining high polymer orientation of n‐type copolymers by temperature rubbing and sequential doping with N‐DMBI results in a strong improvement of electrical conductivity and thermoelectric power factors reaching up to 9.8 ± 1.6 S cm−1 and 8 ± 3 µW m−1.K2, respectively.

Thermo-voltage measurements of atomic contacts at low temperature

Beilstein Journal of Nanotechnology, 2016
We report the development of a novel method to determine the thermopower of atomic-sized gold contacts at low temperature. For these measurements a mechanically controllable break junction (MCBJ) system is used and a laser source generates a temperature ...

Signatures of the Correlated‐Hopping Interaction in Non‐Linear Transport Through a Quantum Dot

Annalen der Physik, EarlyView.
Non‐linear thermoelectric transport through a quantum dot is studied, in order to elucidate the signatures of so‐called correlated hopping. The line shapes of the differential conductance and the Seebeck coefficient as functions of gate voltage are clear indicators of this important interaction term.

Thermopower in Andreev interferometers [PDF]

J. Low Temp. Phys. 136, 401-434 (2004)., 2004
We examine the thermopower Q of a mesoscopic normal-metal (N) wire in contact to superconducting (S) segments and show that even with electron-hole symmetry, Q may become finite due to the presence of supercurrents. Moreover, we show how the dominant part of Q can be directly related to the equilibrium supercurrents in the structure.

Electrical and thermal transport in van der Waals magnets 2H-M_{x}TaS_{2} (M=Mn, Co)

Physical Review Research, 2022
We report a detailed study of electrical and thermal transport properties in 2H-M_{x}TaS_{2} (M=Mn, Co) magnets where M atoms are intercalated in the van der Waals gap. The intercalation induces ferromagnetism (FM) with an easy-plane anisotropy in 2H-Mn_{

Enhanced Thomson and Unusual Nernst Coefficients in 1T‐TiSe2 Due to Bipolar Transport and CDW Phase Transition

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
1T‐TiSe₂ undergoes a charge density wave transition at approximately 200 K. During this phase transition, we observe a significant Thomson coefficient that remains large even after the transition, leading to an unusually broad temperature range with a high Thomson coefficient.

Thermopower of Quantum Hall States in Corbino Geometry as a Measure of Quasiparticle Entropy [PDF]

Phys. Rev. B 85, 195107 (2012), 2012
Using the Onsager relation between electric and heat transport coefficients, and considering the very different roles played by the quantum Hall condensate and quasiparticles in transport, we argue that near the center of a quantum Hall plateau thermopower in a Corbino geometry measures {\it "entropy per quasiparticle per quasiparticle charge"}.

Enhancement in thermoelectric properties due to Ag nanoparticles incorporated in Bi2Te3 matrix

Beilstein Journal of Nanotechnology, 2019
The present study aims to see the enhancement in thermoelectric properties of bismuth telluride (Bi2Te3) annealed at different temperatures (573 and 773 K) through silver (Ag) nano-inclusions (0, 2, 5, 10, 15 and 20 wt %).

Texturization and Dense Dislocations Boost Elastic Bendability of Metallic Thermoelectric Generator

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Both texturization and dense dislocations enabled by the cold‐rolling process achieve a significant enhancement in the elastic strain for the rolled films, ensuring a reservation of the initial transport properties even after 100 000 bending cycles.
