Diffusion of charge carriers

Vedclass · Answer

(C) In forward biasing of a $P-N$ junction diode,the potential barrier is reduced. This allows the majority charge carriers (holes from the $P$-region and electrons from the $N$-region) to cross the junction. This movement of majority charge carriers across the junction is known as diffusion. Therefore,the current in a forward-biased $P-N$ junction is primarily due to the diffusion of majority charge carriers.
