- 1The region near the junction that is depleted of mobile charge carriers is called the depletion region.
- 2The magnitude of the electric field is maximum exactly at the metallurgical junction.
- 3In the depletion region, there are fixed negative ions on the p-side and fixed positive ions on the n-side.
- 4The built-in electric field in the depletion region is directed from the p-side to the n-side.✓
Correct answer
The built-in electric field in the depletion region is directed from the p-side to the n-side.
