The depletion layer in `P-N` junction region is caused by

A

drift of holes

B

diffusion of charge carriers

C

drift of electrons

D

drift of electrons

Text Solution

Verified by Experts

The correct Answer is:
A
Due to difference of concentration of holes and electrons across the junction holes move to the n-side & electrons move to the p-side. This leads to caretion of deplation layer. It is called as diffusion.
