Topological materials for high performance transverse thermoelectrics

Next Energy
Transverse thermoelectrics based on Nernst-Ettingshausen effect have been widely investigated in the 20th century. Old results of transverse thermoelectrics have shown low performances and usually require large magnetic fields. In recent years, the surge

Anomalous Nernst effect in type-II Weyl semimetals

, 2018
Topological Weyl semimetals (WSM), a new state of quantum matter with gapless nodal bulk spectrum and open Fermi arc surface states, have recently sparked enormous interest in condensed matter physics.

Nernst effect in poor conductors and the cuprate superconductors [PDF]

, 2004
We calculate the Nernst signal in disordered conductors with the chemical potential near the mobility edge. The Nernst effect originates from interference of itinerant and localised-carrier contributions to the thermomagnetic transport.

Signatures of an anomalous Nernst effect in a mesoscopic two-dimensional electron system

, 2011
We investigate the Nernst effect in a mesoscopic Two-dimensional Electron System (2DES) at low magnetic fields, before the onset of Landau level quantization. The overall magnitude of the Nernst signal agrees well with semiclassical predictions.

Anomalous Nernst and anisotropic magnetoresistive heating in a lateral spin valve [PDF]

, 2011
We measured the anomalous Nernst effect and anisotropic magnetoresistive heating in a lateral multiterminal permalloy/copper spin valve using all-electrical lock-in measurements. To interpret the results, a three-dimensional thermoelectric finite-element

Anomalous Nernst effect in epitaxial Fe and FexNi1-x alloy thin films

AIP Advances, 2019
The anomalous Nernst effect (ANE) is investigated experimentally in epitaxial fcc FexNi1-x (0≤x≤0.55) alloy thin films and bcc Fe thin film grown on MgO (001) substrates.

Absence of anomalous Nernst effect in spin Seebeck effect of Pt/YIG

AIP Advances, 2016
The Pt/YIG structure has been widely used to study spin Seebeck effect (SSE), inverse spin Hall effect, and other pure spin current phenomena. However, the magnetic proximity effect in Pt when in contact with YIG, and the potential anomalous Nernst ...

Anomalous Nernst and Hall effects in magnetized platinum and palladium

, 2014
We study the anomalous Nernst effect (ANE) and anomalous Hall effect (AHE) in proximity-induced ferromagnetic palladium and platinum which is widely used in spintronics, within the Berry phase formalism based on the relativistic band-structure ...

High-Order Topological Phase Diagram Revealed by Anomalous Nernst Effect in Janus ScClI Monolayer

Higher-order topological properties of two-dimensional(2D) magnetic materials have recently been proposed. In 2D ferromagnetic Janus materials, we find that ScClI is a second-order topological insulator (SOTI).
