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
