We study the role of anharmonicity at interfaces with an added intermediatelayer designed to facilitate interfacial phonon transport. Our resultsdemonstrate that while in the harmonic limit the bridge may lower theconductance due to fewer available channels, anharmonicity can strongly enhancethe thermal conductance of the bridged structure due to added inelasticchannels. Moreover, we show that the effect of anharmonicity on the conductancecan be tuned by varying temperature or the bridge layer thickness, as bothparameters change the total rate of occurrence of phonon-phonon scatteringprocesses. Additionally, we show that the additive rule of thermalresistances(Ohms law) is valid for bridge layer thickness quite shorter thanthe average bulk MFP, beyond the regime it would be expected to fail.
