The doping of minute quantity of antimony to a silicon crystal makes it ………

A

a good insulator.

B

a p-type semiconductor.

C

a n-type semiconductor

D

a good conductor.

Text Solution

Verified by Experts

The correct Answer is:
C
a n-type semiconductor
Antimony is a pentavalent (donar) so n-type semiconductor will form.
