Q. If we mix a pentavalent impurity in a crystal lattice of germanium, what type of semiconductor formation will occur?
A) $p -$type
B) $n -$type
C) Both (a) and (b)
D) None of the two
Explanation
(b)
On adding a pentavalent impurity with germanium, we get $n -$type of semiconductors because excess of electrons is responsible for conduction.
