We measured thermal transport properties of transition metal dichalcogenides hetero-structures by Raman spectroscopy. Excitaiton power dependence and temperature dependence of redshift of Raman peaks enable the estimation of increased temperature by light power injection. The light induced tempearture increase of MoS₂ layer in hetero-structure (on MoSe₂) is larger than that on SiO₂ substrate. This implies that thermalconductivity of MoS₂ is surpressed with formation of hetero-structure.
