Which of the following statements concerning the depletion zone of an unbiased p-n junction is (are) true?

A

The width of the zone is independent of the densities of the dopants (impurities)

B

The width of the zone is dependent on the densities of the dopants (impurities)The width

C

The electric field in the zone is provided by the electrons in the conduction band and holes in the valence band.

D

The electric field in the zone is produced by the ionized dopant atoms.

Text Solution

Verified by Experts

The correct Answer is:
A, D
The width of the depletion zone of p-n junction is independent of the densities of dopant. The electric field across the depletion zone is due to ionized atoms present on the two sides of p-n junction.
