If a small amount of antimony is added to germanium crystal
Options
(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
Correct Answer:
there will be more free electrons than holes in the semiconductor
Explanation:
When small amount of antimony (pentavalent) is added to germanium crystal then crystal becomes n-type semi condcutor. Therefore, there will be more free electron than holes in the semiconductor.
