P type semiconductor: A p-type semiconductor is

A p-type semiconductor is an extrinsic semiconductor created by doping a pure semiconductor crystal (like Silicon or Germanium) with a trivalent impurity. This doping process creates an abundance of electron vacancies, known as 'holes', which act as the majority charge carriers, giving the material its ' p-type ' or positive- type characteristic. P -type Semiconductor Definition: A p -type semiconductor is defined as a semiconductor doped with trivalent impurity atoms, creating holes as the majority charge carriers. Role of Trivalent Impurity Atoms: Trivalent impurities, like boron, have three valence electrons that form bonds with the semiconductor atoms, leaving one incomplete bond or hole. Learn what a p - type semiconductor is, how it is made, and how it differs from an n- type semiconductor . A p - type semiconductor has free holes in its crystal lattice that can move in response to an electric field.
