Quizplus · Accepted Answer

In n-type semiconductors, doping is done with impurities that have more valence electrons than the host material in order to create excess negative charge carriers. Phosphorus (P) is a group V element, meaning it has five valence electrons, while silicon (Si) has only four. Therefore, doping silicon with phosphorus creates an n-type semiconductor by providing extra electrons for conduction.
