## Description

- description: Transverse thermoelectric generation converts temperature gradient
    in one direction into electric field perpendicular to that direction, and is expected
    to be a promising alternative in creating simple-structured thermoelectric modules
    that can avoid the challenging problems facing traditional Seebeck-effect-based
    modules. Recently, large transverse thermopower is observed in closed circuits
    consisting of magnetic and thermoelectric materials, which is referred to as the
    Seebeck-driven transverse magneto-thermoelectric generation (STTG). However, the
    closed-circuit structure complicates its broad applications. Here, we realize
    STTG in the simplest way to combine magnetic and thermoelectric materials, namely,
    by stacking a magnetic layer and a thermoelectric layer together to form a bilayer.
    We derive the expression for its transverse thermopower, which varies with changing
    layer thicknesses and peaks at a much larger value under an optimal thickness
    ratio. This behavior is verified in experiment, through a serial of samples prepared
    by depositing Fe-Ga alloy thin films of various thicknesses onto n-type Si substrates.
    The measured transverse thermopower reaches 15.2±0.4 μV K−1, which is a fivefold
    increase from that of Fe-Ga alloy and much larger than the current room temperature
    record observed in Weyl semimetal Co2MnGa. Our findings highlight the potential
    in combining magnetic and thermoelectric materials for transverse thermoelectric
    applications.
