Phonons are responsible for all thermal properties of a solid, such as its heat content and transport. The anharmonic part of lattice oscillations causes thermal expansion. All these are integral contributions of the phonon spectrum; only at low temperatures, where part of the spectrum can be frozen-out, do they become partially spectrum selective. Thermal conductivity is determined by various mechanisms of phonon scattering.
