Question # 1

What is the difference between intrinsic and extrinsic semiconductors?

  • Ans 1: Intrinsic Semiconductor:A semiconductor in its extremely pure form is known as Intrinsicsemiconductors,Pure elements of silicon and germanium are Intrinsic semiconductors,These semiconductors elements have atoms with four valence electrons.
  • Ans 2: Extrinsic Semiconductor: The doped semiconductors material are called Extrinsic Semiconductor.The electrical behaviour of semiconductors is substantially changed introducing a small impurity into pure semiconductors,and this process is called doping.
