MCQ
Zener breakdown takes place if:
- ADoped impurity is low
- ✓Doped impurity is high
- CLess impurity in $N-$part
- DLess impurity in $P-$type
✓
Answer
Correct option: B.
Doped impurity is high
Zener breakdown occurs due to heavily doped diodes.In this process electrons crosses the barrier from the valence band of the $p-$type to the conduction band of the lightly filled $n-$type material.
