  1. Phonon - Wikipedia

    A phonon is a quasiparticle, collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids.

  2. Phonon | Quantum Mechanics, Wave-Particle Duality & Thermal …

    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 …

  3. Phonon: Definition, Quantization, and Equations - Science Facts

    Jun 10, 2025 · There are two main types of phonons: acoustic phonons and optical phonons. Each type affects how energy moves through a solid material in different ways. Acoustic …

  4. Phonon - an overview | ScienceDirect Topics

    1 Introduction 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 …

  5. Phonons and the Debye Specific Heat - HyperPhysics

    The evidence on the behavior of vibrational energy in periodic solids is that the collective vibrational modes can accept energy only in discrete amounts, and these quanta of energy …

  6. Phonons - The University of Warwick

    A phonon is the elementary excitation in the quantum mechanical treatment of vibrations in a crystal lattice [1] or the quantum unit of a crystal lattice vibration.

  7. Phonon: Types, Properties & Role in Semiconductors Explained

    A phonon is a quantum of vibrational energy that arises from the collective oscillation of atoms within a crystal lattice. In simple terms, just as a photon is a discrete packet of light energy, a …

  8. Explained: Phonons | MIT News | Massachusetts Institute of …

    Jul 8, 2010 · When one of the atoms gets pushed or pulled, it sets off a wave (or phonon) travelling through the crystal, just as sitting down on one edge of a trampoline can set off …

  9. Phonon Definition - Principles of Physics III Key Term | Fiveable

    A phonon is a quantized mode of vibration occurring in a rigid structure, such as a crystal lattice. It represents the smallest unit of vibrational energy that contributes to thermal conductivity and …

  10. PHONON Definition & Meaning - Merriam-Webster

    phonon noun pho· non ˈfō-ˌnän : a quantum of vibrational energy (as in a crystal)
