In a semiconductor , acceptor imparity is

A

Antimony

B

Indium

C

Phosphorus

D

Arsenic

Text Solution

Verified by Experts

The correct Answer is:
B
When a pure Ge crystal is doped with a trivalent impurity like indium, we get a p-type semiconductor. The indium impurity accepts the electrons from Ge, hence it is called acceptor impurity.
