Physics Question on Semiconductor electronics: materials, devices and simple circuits
If the forward bias voltage in a p−n junction diode is decreased, the length of depletion region will
A
Increase
B
Decrease
C
Not change
D
Initially increase and then decrease
Answer
Increase
Explanation
Solution
Due to application of forward biased voltage, the length of depletion region decreases and vice versa. Thus, decrease in forward biased voltage increases the length of depletion region.
