&lt;br /&gt;
A &amp;#039;&amp;#039;&amp;#039;phonon&amp;#039;&amp;#039;&amp;#039; is a quantized vibration of atoms in a [[Physics:Quantum materials/crystal lattice|crystal lattice]]. It represents a collective excitation of the lattice.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div style=&amp;quot;float:right; border:1px solid #e0d890; background:#fff8cc; padding:6px; margin:0 0 1em 1em; width:320px;&amp;quot;&amp;gt;&lt;br /&gt;

&amp;lt;div style=&amp;quot;font-size:90%;&amp;quot;&amp;gt;Phonons describe collective vibrational motion in a crystal lattice.&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Description ==&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
Phonons play an important role in thermal and electrical properties of materials.&lt;br /&gt;
&lt;br /&gt;
== Properties ==&lt;br /&gt;
&lt;br /&gt;
* quantized lattice vibration&lt;br /&gt;
* collective excitation&lt;br /&gt;
* affects thermal and transport properties&lt;br /&gt;
