## Description

- description: In artificially tilted multilayers comprising two different conductors
    that are alternately and obliquely stacked, transverse thermoelectric conversion
    occurs, in which charge and heat currents are interconverted in the orthogonal
    direction. Although transverse thermoelectric conversion also occurs in homogeneous
    materials as an intrinsic transport phenomenon owing to the effects of magnetic
    fields, magnetization, and spins on conduction carriers, such magneto-thermoelectric
    effects are investigated independently of thermoelectrics for artificially tilted
    multilayers. Here, this study shows that the synergy of these different principles
    improves the performance of transverse thermoelectric conversion. Using lock-in
    thermography techniques, transverse thermoelectric conversion processes are visualized
    in artificially tilted multilayers and the experiments clarify how nonuniform
    charge currents are converted into orthogonal heat currents. Through the measurements
    of temperature change under magnetic fields, the contributions of the magneto-thermoelectric
    effects are quantified in the artificially tilted multilayers and magnetically
    enhanced hybrid transverse thermoelectric cooling is demonstrated. By replacing
    one of the conductors in the multilayer with permanent magnets, the same functionality
    is obtained even in the absence of magnetic fields, paving the way for the creation
    of “thermoelectric permanent magnets” that exhibit efficient transverse thermoelectric
    conversion together with spontaneous magnetization. This study provides a new
    material design guideline for transverse thermoelectrics.
