= Ionized impurity scattering
{wiki=Ionized_impurity_scattering}
Ionized impurity scattering is a phenomenon that occurs in semiconductors and other materials where charge carriers (such as electrons and holes) interact with charged impurities present in the material. These charged impurities can be intentionally introduced (as dopants) or can be present as defects in the crystal lattice. \#\#\# Mechanism When a charge carrier moves through a semiconductor, it can experience a scattering event due to the electric fields generated by these ionized impurities.
