Fundamentals and advances in transverse thermoelectrics
Hiroto Adachi, Fuyuki Ando, Takamasa Hirai +3
Transverse thermoelectric effects interconvert charge and heat currents in orthogonal directions due to the breaking of either time-reversal symmetry or structural symmetry, enabli…
Quantitative measurements of transverse thermoelectric generation and cooling performances in SmCo/BiSbTe-based artificially tilted multilayer module
Masayuki Murata, Fuyuki Ando, Takamasa Hirai +2
The transverse thermoelectric generation and cooling performances in a thermopile module composed of recently developed SmCo/BiSbTe artificially tilted mult…
Adiabatic transverse thermoelectric conversion enhanced by heat current manipulation in artificially tilted multilayers
Fuyuki Ando, Takamasa Hirai, Hiroto Adachi +1
We phenomenologically formulate and experimentally observe an adiabatic transverse thermoelectric conversion enhanced by a heat current re-orientation in artificially tilted multil…
Simultaneous achievement of large anomalous Nernst effect and reduced thermal conductivity in sintered polycrystalline topological Heusler ferromagnets
Koichi Oyanagi, Hossein Sepehri-Amin, Kenta Takamori +9
This study reports the observation of the large anomalous Nernst effect in polycrystalline ferromagnetic CoMnGa (CMG) slabs prepared by a spark plasma sintering method. By op…
Designing flexible hard magnetic materials for zero-magnetic-field operation of the anomalous Nernst effect
Sang J. Park, Rajkumar Modak, Ravi Gautam +6
The global shift towards a carbon-neutral society has accelerated the demand for green energy, driving research into efficient technologies for harvesting energy from low-grade was…
