recommendations! Published in 2022 at "Advanced Materials"

DOI: 10.1002/adma.202206941

Abstract: Magnetic topological semimetals provide new opportunities for power generation and solid‐state cooling based on thermoelectric (TE) effect. The interplay between magnetism and nontrivial band topology prompts the magnetic topological semimetals to yield strong transverse TE… read more here.

recommendations! Published in 2021 at "Journal of Low Temperature Physics"

DOI: 10.1007/s10909-021-02593-9

Abstract: We propose a scheme to detect the spin heat accumulation (SHA), an effective spin-dependent electron temperature, via sign reversion of thermopower induced by the Majorana bound states (MBSs) coupled to a quantum dot (QD). The… read more here.

recommendations! Published in 2022 at "Nature Physics"

DOI: 10.1038/s41567-022-01574-3

Abstract: Thermopower, a non-invasive probe, is a sensitive tool to study the electronic structure near the singular points of Fermi surface as its magnitude and sign depends on the asymmetry of the density of states at… read more here.

DOI: 10.1038/srep44276

Abstract: Molecular junction is a chemically-defined nanostructure whose discrete electronic states are expected to render enhanced thermoelectric figure of merit suitable for energy-harvesting applications. Here, we report on geometrical dependence of thermoelectricity in metal-molecule-metal structures. We… read more here.

DOI: 10.1103/physrevb.97.245425

Abstract: Motivated by recent proposal by Potter et al. [Phys. Rev. X 6, 031026 (2016)] concerning possible thermoelectric signatures of Dirac composite fermions, we perform a systematic experimental study of thermoelectric transport of an ultrahigh-mobility GaAs/AlxGa1-xAs… read more here.
