Question

Explain the formation of depletion region in a p-n junction diode

Answer 1

Explanation:

Depletion Region

When a p-n junction is formed, some of the free electrons in the n-region diffuse across the junction and combine with holes to form negative ions. In so doing they leave behind positive ions at the donor impurity sites.

Answer 2

Answer:

Explanation:

Width of the depletion region in a P-N junction decreases when it is forward biased whereas increases when it is reversed biased.
