Not in JEE Advanced syllabus

In the reverse biasing of a p-n junction diode

(A)the width of the depletion layer decreases
(B)the width of the depletion layer increasesCorrect
(C)the number of minority charge carries increases
(D)the number of majority charge carriers increase

Answer: (B)

Solution

In reverse bias the p-side is connected to the negative terminal of the battery and the n-side to the positive terminal. The applied field is in the same direction as the junction (barrier) field, so holes and electrons are pulled away from the junction; the depletion layer widens and the barrier height
