Electrically tunable giant Nernst effect in two-dimensional van der Waals heterostructures

Andras Kis, Guilherme Migliato Marega, Zhe Sun, Gabriele Pasquale

The Nernst effect, a transverse thermoelectric phenomenon, has attracted significant attention for its potential in energy conversion, thermoelectrics and spintronics. However, achieving high performance and versatility at low temperatures remains elusive. ...

Investigation of thermoelectric nanomaterials

David Thomas Osenberg

Thermoelectric conversion remains an active research field in light of its potential to enhance energy efficiency by waste heat recovery in a noise and wear-free manner.Nanostructuring is responsible for most of the recently reported improvements of the fi ...

Strong temperature-dependent thermoelectric power of IrMn(3)thin films of different thicknesses

Jean-Philippe Ansermet, Haiming Yu, Junfeng Hu, Mukund Krishna Kothari

IrMn(3)thin films were experimentally characterized by thermoelectric power and resistivity as a function of temperature and sample thickness. The Seebeck coefficient shows strong temperature dependence and the value increases with temperature up to 350 K. ...

Record thermopower found in an IrMn-based spintronic stack

Jean-Philippe Ansermet, Peng Gao, Haiming Yu, Sa Tu, Junfeng Hu, Jianyu Zhang, Yao Zhang, Song Liu

The Seebeck effect converts thermal gradients into electricity. As an approach to power technologies in the current Internet-of-Things era, on-chip energy harvesting is highly attractive, and to be effective, demands thin film materials with large Seebeck ...

The influence of the incommensurately modulated structure on the physical properties of Fe1.35Ge

László Forró, Alla Arakcheeva, Helmuth Berger, Philip Pattison, Krunoslav Prsa, Andrea Pisoni, Sergiy Katrych, Jacim Jacimovic

Single crystal growth by chemical vapour transport has resulted samples with Fe1.35Ge stoichiometry. Structural study has shown that the large number of vacancies introduces an incommensuately modulated structure. The electrical resistivity is in the 200 m ...
