When a p-n junction diode is forward biased

Q1 FREE PREVIEW

When a p-n junction diode is forward biased

a

the barrier height and the depletion layer width both increase.

b

the barrier height increases and the depletion layer width decreases.

c

the barrier height and the depletion layer width both decrease.

d

the barrier height decreases and the depletion layer width increases.

✓ Correct answer: c)

the barrier height and the depletion layer width both decrease.

Explanation

barrier height and the depletion layer width both decrease. When p-n junction is forward biased: • The barrier potential decreases. • The depletion layer width decreases due to carrier injection.
