Charge carriers

thumb|right|300px|Electron transfer from a neutral lithium (Li) atom on the left to a neutral [[fluorine (F) atom on the right would give Li and F ions.]]

conceptual and mathematical opposite of an electron

quantum mechanical state change

pair of electrons or other fermions bound together at low temperature allowing for superconductivity

particle free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors

particle with a nonzero electric charge

average velocity attained by charged particles in a material due to electric field

thumb|right|420 px|Carrier and channel ionophores (a) Carrier ionophores reversibly bind ions and carry them through cell membranes. (b) Channel ionophores create channels within cell membranes to facilitate the transport of ions.

characterizes how quickly an electron can move through a metal or semiconductor, when pulled by an electric field

principle in the function of solid-state electronic devices

a process by which mobile charge carriers (electrons and electron holes) are created and eliminated

charge carriers per volume; such as electrons, ions, "holes" or others

Movement of charge carriers with negligible scattering

faradaic current that is controlled by the diffusion of electroactive species

is the electric current, or movement of charge carriers, which is due to the applied electric field, often stated as the electromotive force over a given distance
