Peak intrinsic thermal conductivity in non-metallic solids and new interpretation of experimental data for argon
Ahmed Hamed, Anter El-Azab
The inelastic nature of 3-phonon processes is investigated within the framework of perturbation theory and linearized Boltzmann Transport Equation. By considering the energy conser…
