Keywords:Interfacial thermal resistance, Numerical calculation, Phonon transport

We calculated the interfacial thermal resistance between Perovskite and Bismuth Telluride by using DMM model. The phonon dispersion relations of both Provskite and Bismuth Telluride are calculated by ab-intio calculation. The calculated value is one order higher than the interfacial thermal resistance between inorganic materials.
