Interface‐Engineered Bi0.5Sb1.5Te3/WSe2 Heterostructures for Enhanced Thermoelectric Performance
BST/WSe2 heterostructures grown by pulsed laser deposition exhibit semicoherent van der Waals interfaces, characterized by lattice strain, compressed gaps, and localized moiré patterns. These interfacial features modulate carrier generation and energy filtering, yielding high Seebeck coefficients and a consistently high power factor above 50 µW cm−1 K ...

Giant thermoelectric effects in a proximity-coupled superconductor–ferromagnet device
The usually negligibly small thermoelectric effects in superconducting heterostructures can be boosted dramatically due to the simultaneous effect of spin splitting and spin filtering. Building on an idea of our earlier work (Machon et al 2013 Phys. Rev.

Resonant Charge Relaxation as a Likely Source of the Enhanced Thermopower in FeSi
The enhanced thermopower of the correlated semiconductor FeSi is found to be robust against the sign of the relevant charge carriers. At $T$\,$\approx$\,70 K, the position of both the high-temperature shoulder of the thermopower peak and the nonmagnetic ...

Low-field diffusion magneto-thermopower of a high mobility two-dimensional electron gas [PDF]
The low magnetic field diffusion thermopower of a high mobility GaAs-heterostructure has been measured directly on an electrostatically defined micron-scale Hall-bar structure at low temperature (T = 1.6 K) in the low magnetic field regime (B < 1.2 T ...

Finite-frequency thermoelectric response in strongly correlated quantum dots
We investigate the finite-frequency thermal transport through a quantum dot subject to strong interactions, by providing an exact, nonperturbative formalism that allows us to carry out a systematic analysis of the thermopower at any frequency.

Thermoelectric generators (TEGs) convert waste heat into electricity for self‐powered and wearable electronics. This review highlights advances in flexible, hybrid, and ionic thermoelectric materials, emphasizing ionic thermopower control, textile integration, and hybrid TEG–supercapacitor systems for combined harvesting, sensing, and storage.

Thermo-voltage measurements of atomic contacts at low temperature
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 ...

N-type thermoelectric performance of functionalized carbon nanotube-filled polymer composites. [PDF]
Carbon nanotubes (CNTs) were functionalized with polyethyleneimine (PEI) and made into composites with polyvinyl acetate (PVAc). CNTs were dispersed with different amounts of sodium dodecylbenzenesulfonate (SDBS) prior to the PEI functionalization.

Thermopower induced by a supercurrent in superconductor-normal-metal structures
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.
