At absolute zero temperature, pure silicon behaves as

Options

  1. Aextrinsic semiconductor
  2. Bnon-metal
  3. Cinsulator
  4. Dmetal

Correct answer

C. insulator

Step-by-step solution

(C) The semiconductor (Si) has negative temperature coefficient of resistivity. At absolute zero temperature, its resistance becomes infinite and it act like an insulator.
