## Description

- description: We phenomenologically formulate and experimentally observe an adiabatic
    transverse thermoelectric conversion enhanced by a heat current re-orientation
    in artificially tilted multilayers (ATMLs). By alternately stacking two materials
    with different thermal conductivities and rotating its multilayered structure
    with respect to a longitudinal temperature gradient, off-diagonal components in
    the thermal conductivity tensor are induced. This off-diagonal thermal conduction
    (ODTC) generates a finite transverse temperature gradient and Seebeck-effect-induced
    thermopower in the adiabatic condition, which is superposed on the isothermal
    transverse thermopower driven by the off-diagonal Seebeck effect. In this study,
    we calculate and observe the two-dimensional temperature distribution and the
    resultant transverse thermoelectric conversion in ATMLs comprising thermoelectric
    Co2MnGa Heusler alloys and Bi2-aSbaTe3 compounds. By changing the tilt angle from
    0° to 90°, the transverse temperature gradient obviously appeared in the middle
    angles and the transverse thermopower increases up to -121.9 μV/K in Co2MnGa/Bi0.2Sb1.8Te3-based
    ATML at the tilt angle of 45° whereas the isothermal contribution is estimated
    to be -82.6 μV/K from the analytical calculation. This hybrid action derived from
    ODTC results in the significant enhancement of the maximum reduced conversion
    efficiency from 3.1% to 8.1% in calculation and from 2.3% to 4.4% in experiment.
