Microscale Heat Conduction in Dielectric Thin Films
TLDR
Based on Boltzmann transport theory, an equation of phonon radiative transfer (EPRT) was developed in this paper, where the phonon-scattering mean free path was used to analyze heat transport by lattice vibrations or phonons.Abstract:
Heat conduction in dielectric thin films is a critical issue in the design of electronic devices and packages. Depending on the material properties, there exists a range of film thickness where the Fourier law, used for macroscale heat conduction, cannot be applied. In this microscale regime, heat transport by lattice vibrations or phonons can be analyzed as a radiative transfer problem. Based on Boltzmann transport theory, an equation of phonon radiative transfer (EPRT) is developed. In the acoustically thick limit, ξ L >>1, or the macroscale regime, where the film thickness is much larger than the phonon-scattering mean free path, the EPRT reduces to the Fourier lawread more

Experimental support for the lagging behavior in heat propagation
TL;DR: In this paper, the authors examined the lagging behavior for heat transport in small-scale and fast-transient processes and employed the phase-lag concept to describe the special response observed in these experiments.
