A p-type extrinsic semiconductor is obtained when Germanium is doped with
  1. Arsenic
  2. Boron
  3. Antimony
  4. 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).
