The increase in the width of the depletion region in a p-n junction diode is due to :
Updated On: Apr 14, 2025
- forward bias only
- reverse bias only
- both forward bias and reverse bias
- increase in forward current
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In reverse bias, external battery attracts majority charge carriers
So, width of the depletion region increases
So, width of the depletion region increases

Concepts Used:
Semiconductors
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
Properties of Semiconductor:
- Semiconductor acts like an insulator at Zero Kelvin. On increasing the temperature, it works as a conductor.
- Due to their exceptional electrical properties, semiconductors can be modified by doping to make semiconductor devices suitable for energy conversion, switches, and amplifiers.
- Lesser power losses.
Uses of Semiconductor:
- Semiconductors are widely used in manufacturing electronics devices like transistors, diodes, sensors, integrated circuits.
