Description

In physics, a phonon is a quasiparticle characterized by the quantization of the modes of lattice vibrations of periodic, elastic crystal structures of solids. The study of phonons is an important part of solid state physics because phonons play a major role in many of the physical properties of solids, including a material's thermal and electrical conductivities.
