Class 12 Physics Semiconductor Electronics Extrinsic semiconductor

Extrinsic semiconductor

  • A doped semiconductor or a semiconductor with suitable impurity added to it is called extrinsic semiconductor
  • There are two types – n-type and p-type
  • In n-type semiconductor, the electrons are the majority carriers while the holes are the minority carriers
  • In p-type semiconductor, the holes are the majority carriers while the electrons are the minority carriers
  • A detailed study of n-type and p-type semiconductors, help us to understand better about the extrinsic semiconductor
