A p-type extrinsic semiconductor is obtained when Germanium is doped with

Options

  1. AArsenic
  2. BBoron
  3. CAntimony
  4. DPhosphorous

Correct answer

B. Boron

Step-by-step 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).
