Charge carriers per volume; such as electrons, ions, "holes" or others
This article is about the number of individual electrons or holes per volume. For the electric charge per volume, see charge density. For the number of possible states per energy range, see density of states.
Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m−3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.
Charge carrier densities involve equations concerning the electrical conductivity, related phenomena like the thermal conductivity, and chemicals bonds like covalent bond.
