Phonon - Wikipedia
Definition. A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency. [4] In classical mechanics this designates a normal mode of vibration.

2010年7月8日 · Physicists call these basic levels of energy phonons. In a sense, then, “phonon” is just a fancy word for a particle of heat. Phonons are especially relevant in the behavior of heat and sound in crystals, explains Gang Chen, the Soderberg Professor of Power Engineering at …
phonon - Encyclopedia Britannica
2024年10月15日 · phonon, in condensed-matter physics, a unit of vibrational energy that arises from oscillating atoms within a crystal. Any solid crystal, such as ordinary table salt (sodium chloride), consists of atoms bound into a specific repeating …
Phonon: Definition, Quantization, and Equations - Science Facts
2024年11月5日 · Phonon. Phonons are tiny packets of energy that come from the vibrations of atoms in a solid. In solids, atoms are arranged in a regular, repeating pattern called a lattice, where each atom vibrates around its fixed position. These vibrations or phonons travel through the solid in fixed, tiny amounts, carrying energy with them.
Phonon - Explanation, Types, Properties and In Semiconductor
Phonon Meaning. According to the phonon definition, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules condensed specifically in solids and some liquids.
Phonon - Quantiki
A phonon is a quantized mode of vibration occurring in a rigid crystal lattice, such as the atomic lattice of a solid. The study of phonons is an important part of solid state physics, because phonons play an important role in many of the physical properties of solids, such as the thermal conductivity and the electrical conductivity. In ...
Phonon - an overview | ScienceDirect Topics
A phonon is a collective excitation in condensed matter, which is a quantization of the vibration mode in elastic structures. Although phonons are not as popular as photons or electrons, they are ubiquitous in our daily lives.
