| Abstract Scope |
Transverse thermoelectric conversion, which allows interconversion between heat and charge currents in the orthogonal directions, holds significant potential in addressing several challenges posed by the conventional longitudinal Seebeck effect. The ordinary/anomalous Nernst effect induced by magnetic field and/or magnetization is promising transverse thermoelectric phenomena and a number of hopeful materials for Nernst-effect-based transverse thermoelectric devices have been discovered in spintronics and topological materials science. However, the currently reported performance of such magneto-thermoelectric effects is quite insufficient for practical applications.
In this talk, I will introduce two concepts: “hybrid transverse magneto-thermoelectric conversion” and “thermoelectric permanent magnet” based on artificially tilted multilayers. The synergy between the oblique and alternating structure and magnetics/spintronics idea significantly increases the performance of Nernst effects and gives a new functionality to thermoelectric devices. |
