## Description

- description: The spin Peltier effect (SPE) in Pt/WSe2/Y3Fe5O12 (YIG) and Pt/WS2/YIG
    heterostructures is investigated using lock-in thermography. Since inserting atomically
    thin transition metal dichalcogenides (TMDs), such as WSe2, between Pt and YIG
    is known to enhance the voltage induced by the spin Seebeck effect, similar enhancement
    is expected for SPE. Contrary to this expectation, the SPE-induced temperature
    modulation is strongly suppressed in the TMD-inserted regions compared with bare
    Pt/YIG regions. Raman spectroscopy reveals sputtering-induced structural degradation
    of WSe2, hindering spin-current injection into YIG. These results highlight the
    sensitivity of spin-current transport to interface quality in spin-caloritronic
    devices incorporating atomically thin TMDs.
