(a) Computed heat flux suppression functions at different filling fractions based on solving the phonon Boltzmann transport equation. (b) Computed kernel functions versus filling fractions. (c–f) Comparison of experimentally reconstructed silicon MFP distributions and predictions from DFT calculations at four different temperatures. The MFP distribution describes the fractional thermal conductivity contribution from thermal phonons with MFPs shorter than a prescribed value.
