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. In the world of semiconductor electronics, understanding doping and charge‐carrier behavior is key. A p -type semiconductor is a type of extrinsic semiconductor created by adding a small amount of a trivalent impurity to a pure (intrinsic) material such as silicon or germanium. This intentional impurity introduction, known as doping, leads to the creation of “holes”—vacancies for electrons—that become the majority charge carriers. Because these holes carry positive charge, the ... 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.
