Question

The Potential Barrier in the depletion layer is due to

• A. Ions
• B. Holes
• C. Electrons
• D. Forbidden Band

Answer 1

The correct option is A

Ions

Depletion layer:

1. The depletion layer is the ion-free region at the junction of a diode. As a result, the potential barrier in the depletion layer is caused by ions.
2. The depletion region is the layer in which the charge flow decreases.
3. This region acts as a barrier, preventing electrons from flowing from the n-side to the p-side of the semiconductor diode.

Therefore, the potential barrier in the depletion layer is due to the Ions
