Question

Match List-I with List-II (Semiconductor types vs position of Fermi level).

• A. A-I, B-III, C-II, D-IV
• B. A-II, B-I, C-IV, D-III
• C. A-I, B-II, C-IV, D-III
• D. A-IV, B-III, C-II, D-I

Hint:

n-type → conduction band, p-type → valence band.

Answer 1

The Correct Option is C

Concept: Fermi level position:
• Intrinsic → middle of bandgap
• n-type → near conduction band
• p-type → near valence band
• Degenerate → inside band

Step 1: Match \[ A \rightarrow I,\quad B \rightarrow II,\quad C \rightarrow IV,\quad D \rightarrow III \] \[ \therefore \text{Correct answer is (C)} \]
