If the p-region (anode) is connected to the positive terminal of the external DC source and n-side (cathode) is connected to the negative terminal of the DC source then the biasing is said to be “forward biasing”. . 1. Recap. Three important phenomena occurs during formation of . pn. junction: Diffusion, Formation of Space charge and Drift.. Movement of electrons from n-side to p-side (n>p) and the movement of holes from p-side to n-side is called (p>n) “. A . pn. junction is known as a . semi-conductor . or . crystal . diode. ..

Zero Bias. condition, no external potential energy is applied to the PN junction. However, if the diodes terminals are shorted together, a few holes (majority carriers) in the P-type material with enough energy to overcome the potential barrier will move across the junction against this barrier potential.
