Answer to: Define Built-in Potential in a PN Junction. With the help of diagrams, explain how the built-in potential is formed when no external...
This difference in potential is called the diffusion potential (VD) or built-in potential. Electrons are the majority charge carriers in the n-type semiconductor whereas holes are the majority charge carriers in the p-type semiconductor. Near the junction, electrons in the n-ty...

This is called the depletion region of the PN junction diode. The Efield produces by the minority carriers in turn produces a built in potential called Vbi. My question? 1). If I put a voltage meter across a PN junction diode. I get 0 V. Why don't I get Vbi? 2). What if ...
