Vedclass · Answer

(A) $P-N$ junction is the interface between $p$-type and $n$-type semiconductors. When both semiconductors are joined,charge carriers diffuse across the junction. Specifically,electrons from the $n$-region move towards the $p$-region,and holes from the $p$-region move towards the $n$-region. This diffusion leaves behind immobile ionized atoms near the junction,creating a depletion region. The electric field generated by these immobile ions creates a barrier potential. This barrier potential opposes the further diffusion of majority charge carriers (electrons in the $n$-region and holes in the $p$-region) across the junction. Therefore,the barrier potential offers resistance to the free electrons in the $n$-region and holes in the $p$-region.
