AC thermal conductivity as a tool for solution mapping from diffusive to ballistic regime
Tao Li, Bo Jiang, Zhen Chen
Although the Boltzmann transport equation (BTE) has been exploited to investigate non-diffusive phonon transport for decades, due to the challenges of solving this integro-differen…

Anisotropic Klemens model for the thermal conductivity tensor
Bo Jiang, Tao Li, Zhen Chen
With the constraint from Onsager reciprocity relations, here we generalize the Klemens model for phonon-phonon Umklapp scattering from isotropic to anisotropic. Combined with the a…
