Question

In a semiconductor diode, the reverse biased current is due to drift of free electrons and holes caused by the

• A. Thermal excitations only
• B. Impurity atoms only
• C. Both (1) & (2)
• D. Neither (1) or (2)

Answer 1

The correct option is D Neither (1) or (2)

The reversed bias current in a diode is due to recombination of holls and electrons from their respective sides. A strong electric field directs the electrons towards its thus creating a conducting path

So,it is due to voltage Expectations only
