Vibrational hierarchy leads to dual-phonon transport in low thermal conductivity crystals
Many low-thermal-conductivity (κ(L)) crystals show intriguing temperature (T) dependence of κ(L): κ(L) ∝ T(−1) (crystal-like) at intermediate temperatures whereas weak T-dependence (glass-like) at high temperatures. It has been in debate whether thermal transport can still be described by phonons at...
