Fig. 6: The dispersion relation for a phonon in the case of diatomic materials in 3D form.

From: There is plenty of room at the top: generation of hot charge carriers and their applications in perovskite and other semiconductor-based optoelectronic devices

a The predominant routes of phonon decay start from their origin center as LO phonons and progressively turn into lower energy acoustic phonons that are responsible for the dissipation of heat. b The four types of decay mechanisms are depicted as Klemens, Ridely, Vallee–Bogani, and Barman–Sirvastava. The figures are taken with permission from ref. 13
