Question

State some important features of the depletion region.

✓

Answer

It is formed by diffusion of electrons from n-region to the p-region. This leaves positively charged ions in the n-region.
The p-region accumulates electrons (negative charges) and the n-region accumulates the holes (positive charges).
The accumulation of charges on either sides of the junction results in forming a potential barrier and prevents flow of charges.
There are no charges in this region.
The depletion region has higher potential on the n-side and lower potential on the p-side of the junction.
