Typical range of conductivities for insulators, semiconductors, and conductors.
In a p-n junction, the majority charge carriers are determined by the type of impurity doping present on each side of the junction:
- p-side: Holes are the majority carriers, as this side is doped with acceptor impurities.12
- n-side: Electrons are the majority carriers, as this side is doped with donor impurities.12
Conversely, the less abundant carriers on each sideāelectrons on the p-side and holes on the n-sideāare referred to as minority carriers.13
