A p-type extrinsic semiconductor is obtained when Germanium is doped with
Arsenic
Boron
Antimony
Phosphorous
Solution
To make a p-type semiconductor, an intrinsic semiconductor is doped with an intrinsic impurity which has 3 valence electrons in its outer orbit.
For example - Gallium, Indium, Boron, Aluminium.
So, correct answer is option (2).
