Charge carrier - Wikipedia
In conducting media, particles serve to carry charge:
• In many metals, the charge carriers are electrons. One or two of the valence electrons from each atom are able to move about freely within the crystal structure of the metal. The free electrons are referred to as conduction electrons, and the cloud of free electrons is called a Fermi gas. Many metals have electron and hole bands. In some, the majority carriers are holes.Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 7 mins
