A phonon is a quantized vibration of atoms in a crystal lattice. It represents a collective excitation of the lattice.
Description
In a solid, atoms vibrate about their equilibrium positions. These vibrations can be described as waves, and when quantized, they behave as particles called phonons.
Phonons play an important role in thermal and electrical properties of materials.
Properties
- quantized lattice vibration
- collective excitation
- affects thermal and transport properties
