(solid-state physics)
A mobile conduction electron or mobile hole in a semiconductor. Also known as carrier.

Carrier, Charge

 

(or simply carrier), a particle or quasi-particle that is capable of carrying an electric charge through a given substance. The term is most frequently used in solid-state physics, where the charge carriers are usually conduction electrons and holes.
