State some important features of the depletion region.

1.	State some important features of the depletion region.
Answer» 1. It is formed by diffusion of electrons from n-region to the p-region. This leaves positively charged ions in the n-region. 2. The p-region accumulates electrons (negative charges) and the n-region accumulates the holes (positive charges). 3. The accumulation of charges on either sides of the junction results in forming a potential barrier and prevents flow of charges. 4. There are no charges in this region. 5. The depletion region has higher potential on the n-side and lower potential on the p-side of the junction.
