While the determination of interfacial thermal resistance in AFM-IR using custom transducers has previously been demonstrated 7,37 specialized, high frequency AFM-IR tips were demonstrated for the determination of this often elusive parameter, our results hint at alternative approach that leverages the frequency dependent AFM-IR image combined with modeling. In this work, the interfacial thermal resistance between PMMA absorber and PE was found to be ≈2.2 m 2 K/MW.
