Phonon-Polariton in Heat Conduction

Abstract

It is well-known that the contribution of radiative transport to thermoconductivity of majority of solids is important only at rather high temperatures of the order of a few thousands K. At much lower temperatures the radiative transport is usually small because is small the density of photon states which have an energy of the order of kBT. The energy of the transverse photons responsible for the radiative transport (we assume that the medium is isotropic), is E(k) = hck/square root of epsilon, where c is the velocity of photon in vacuum, k is its wave vector and epsilon is the dielectric constant of medium.
