If a small amount of antimony is added to germanium crystal

A

its resistance is increased

B

it becomes a p-type semiconductor

C

there will be more free electrons than holes in the semiconductor

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
Adding fifteenth group element to germanium makes it an n-type semiconductor. Antimony is a fifteenth group element and so germanium becomes n-type semiconductor.
