Doping of silicon (Si) with indium (In) leads to the formation of
- A \(n\)-type semiconductor
- B metal
- C \(p\)-type semiconductor
- D insulator
Answer & Solution
Correct Answer
(C) \(p\)-type semiconductor
Step-by-step Solution
Detailed explanation
Silicon (Si) belongs to Group 14 of the periodic table and has 4 valence electrons. Indium (In) belongs to Group 13 of the periodic table and has 3 valence electrons. When silicon is doped with indium, the indium atoms replace some silicon atoms in the crystal lattice. Since…
