If a small amount of antimony is added to germanium crystal

A

the antimony becomes an acceptor atom

B

there will be more free electrons than holes in the semiconductor

C

its resistance is increased

D

it becomes a `p`-type semiconductor

Text Solution

Verified by Experts

The correct Answer is:
B
When a small amount of antimony is added to germanium crystal, the crystal becomes `n`-type semiconductor because antimony is a pentavelent substrate. It excess free electrons.
