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

Answer

C

Explanation

When a small amount of antimony (pentavalent) is added to germanium (tetravalent) crystal, then crystal becomes b - type semiconductor. In n - type semicondcutor electrons are the majority charge carriers and the holes are the minority. Charge carrers.
