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

A

drift of holes

B

diffusion of charge carriers

C

migration of impurity ions

D

drift of electrons

Text Solution

Verified by Experts

The correct Answer is:
B
Due to high concentration of electrons in `n`side and of holes in `p`-side, they diffuses to other side, hence depletion region is created.
