Abstract

The effect of electron-phonon coupling on thermal conductance across metal-dielectric interfaces remains inconclusive. The leading model employs the phonon thermal conductivity of the metal that is difficult to estimate. We remove this difficulty by obtaining the conductance directly from the Bloch-Boltzmann-Peierls formula, describing the matrix element using a deformation potential that can be estimated from the electrical resistivity data. We report calculations up to 500 K to show that electron-phonon coupling is not a major contributor to the thermal resistance across metal-dielectric interfaces. Our method advances understanding of the role of electron-phonon coupling in limiting thermal transport near metal interfaces.
