Physics Question on Semiconductor electronics: materials, devices and simple circuits
The increase in the width of the depletion region in a p-n junction diode is due to :
A
forward bias only
B
reverse bias only
C
both forward bias and reverse bias
D
increase in forward current
Answer
reverse bias only
Explanation
Solution
In reverse bias, external battery attracts majority charge carriers
So, width of the depletion region increases
