If a small amount of antimony is added to germanium crystal

A

it becomes a p-type semiconductor

B

the antimony becomes an acceptor atom

C

there will be more free electrons than holes in the semiconductor

D

its resistance is increased.

Text Solution

Verified by Experts

The correct Answer is:
C
When small amount of antimony (pertavalent) is added to germanium crystal then crystal becomes n-type semi conductor.
