Question
If a small amount of antimony is added to germanium crystal
Options
A.it becomes a p-type semiconductors
B.the antimony becomes an acceptor atom
C.there will be more free electrons than holes in the semiconductor
D.its resistance is increased.
Solution
When a small amount of antimony (pentavalent) is aded to germanium (tetravalent)crystal, the crystal becomes n-type semiconductor. In n-type semiconductor electrons are the majority charge carriers and hole are the monority charge carriers.
