The dominant contribution to current comes from holes in case of

Options

  1. Ametals
  2. Bintrinsic semiconductors
  3. Cp-type extrinsic semiconductors
  4. Dn-type extrinsic semiconductors

Correct answer

C. p-type extrinsic semiconductors

Step-by-step solution

The semiconductors in which majority charge carriers are holes i.e. positinely charged and minority charge are holes, so, in p-type semiconductor, the holes movement results in the formation of the current.
