Abstract:  
The existence of a universal interfacial thermal resistance in a broad range of systems is shown using linear response theory and computations of realistic materials. When the thermal excitation is modulated up to
frequencies larger than the intrinsic resistance scattering rate defined in a previous paper [A. Rajabpour and S. Volz, J. Appl. Phys. 108, 094324 (2010)], the interfacial resistance becomes reversely proportional to
frequency and only depends on the number of degrees of freedom involved in the heat transfer between both
systems. We present molecular dynamics simulations of connected crystals corroborating these statements from
both quantitative and qualitative viewpoints. This finding significantly impacts the thermal management of
nanoelectronic systems at nanoscales where heat removal mainly relies on interfacial scattering.
