What is the difference between intrinsic semiconductor and extrinsic semiconductor?
  • a)
    Extrinsic semiconductor does not flow current at room temperature while intrinsic semiconductor allow to flow current at room temperature.
  • b)
    Holes and electrons are equal in extrinsic semiconductor while in intrinsic they are not equal.
  • c)
    Extrinsic semiconductor is the pure semiconductor and intrinsic semiconductor is conductor with some impurity.
  • d)
    Intrinsic semiconductor is the pure semiconductor and extrinsic semiconductor is conductor with some impurity.
Correct answer is option 'D'. Can you explain this answer?

What is the difference between intrinsic semiconductor and extrinsic s...
  • Option 1: The conductivity of an intrinsic semiconductor is very low at room temperature. It means very low or no current flows at room temperature.
    • So this is an incorrect statement.
  • Option 2: Since intrinsic semiconductors are pure semiconductors they have the same number of holes and electrons. 
  • Option 3 and 4: The intrinsic semiconductor is a pure semiconductor and an extrinsic semiconductor is a semiconductor with impurity.
    • So option 4 gives the correct statement.
So the correct answer is option 4.
