Reverse bias applied to a p-n junction diode
Reverse bias applied to a p-n junction diode
Updated On: Jul 28, 2022
- lowers the potential barrier
- decreases the majority charge carriers
- raises the potential barrier
- change the mass of p-n junction diode
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In reverse bias applied to a p-n junction diode raises the potential barrier because p-type material conncted to the negative terminal and pullesthe holes away from the junction.
Similarly n-type material connected to positive terminal and pulles the electrons. Therefore the depletion region widens.

Concepts Used:
P-n Junction
A P-N junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor.
Biasing conditions for the p-n Junction Diode:
in p-n junction diode two operating regions are there:
- P-type
- N-type
There are three biasing conditions for p-n junction diode are as follows:
- Zero bias: When there is no external voltage applied to the p-n junction diode.
- Forward bias: P-type is connected to positive terminal of the voltage potential while n-type is connected to the negative terminal.
- Reverse bias: P-type is connected to negative terminal of the voltage potential while n-type is connected to the positive terminal.
