Vedclass · Answer

(B) In an unbiased $p-n$ junction,the diffusion of electrons from the $n$-region to the $p$-region and holes from the $p$-region to the $n$-region occurs near the junction. When these charge carriers cross the junction,they recombine and neutralize each other. As a result,the region near the junction becomes devoid of mobile charge carriers (free electrons and holes). This region is called the depletion layer or depletion region. Therefore,the layer is depleted of mobile charge carriers,which are electrons and holes.

The region near the junction of an unbiased $p-n$ junction diode is known as the depletion layer. This layer is depleted of
