The width of the depletion region in a PN junction depends on the:
Correct answer: C. Doping of both the p and n-materials
- A. Doping of p-materials
- B. Doping of n-materials
- C. Doping of both the p and n-materials
- D. None of these
Explanation
The width of the depletion region in a PN junction primarily depends on the doping concentrations of the P-type and N-type semiconductor materials and the applied voltage across the junction. Higher doping concentrations result in a narrower depletion region. A higher density of dopant atoms leads to a higher concentration of majority carriers near the junction, reducing the width of the depletion region.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
