Difference between pn and np diode

WebzIn thermal equilibrium, the PN diode has a potential difference for electrons, and a potential difference for holes, and an electric field that both see, with zero voltage appearing at the contacts, because the contacts are at the voltage of the Fermi level, not the conduction band on both sides or the valence band on both sides. http://www.differencebetween.net/technology/difference-between-p-n-junction-diode-and-zener-diode/
