(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.

While the identity of the charge carriers in nonpolar fluids is generally not known, it is generally agreed upon that the number of charge carriers is a very small fraction of the total number of ionic or neutral species from which they originate [8,9].
The increasing of the conductivity is small at high frequencies; this is attributed to the electronic polarization and the electronic charge carriers which travel by hopping process.

At extremely low temperature, the charge carrier mobility (electrons) and the number of thermally generated charge carriers are significantly reduced, and thus the conduction mechanism is mainly attributed to the localized hopping process in the system as proposed by Mott [41], This is why the conduction in composite is non-ohmic in nature at 25 K.
