Identify the correct statements among the following. (A) At 0 K, the resistance of a semiconductor is infinite. Choose the correct answer from the options given below: |
(A), (B) and (C) only (B), (C) and (D) only (A), (B) and (D) only (A) and (D) only |
(A), (B) and (D) only |
The correct answer is Option (3) → (A), (B) and (D) only Analysis of statements: (A) At 0 K, the resistance of a semiconductor is infinite → True. No electrons are in the conduction band at absolute zero. (B) In an n-type semiconductor, the electron concentration is approximately equal to the concentration of donor atoms → True. Electrons donated by donor atoms dominate. (C) In p-type semiconductors, the acceptor levels lie near the conduction band → False. Acceptor levels lie near the valence band. (D) In n-type semiconductors, the charge carriers are both electrons and holes → True. Electrons are majority carriers, holes are minority carriers. Correct Statements: (A), (B), and (D) |
