In a n -type semiconductor, which of the following statement is true?

Options

  1. AElectrons are majority carriers and trivalent atoms are dopants
  2. BElectrons are minority carriers and pentavalent atoms are dopants
  3. CHoles are minority carriers and pentavalentf atoms are dopants
  4. DHoles are majority carriers and trivalent atoms are dopants

Correct answer

C. Holes are minority carriers and pentavalentf atoms are dopants

Step-by-step solution

The r-type sem-iconductor can be produced by doping an impurity atom of valence 5 i.e., pentavalent atoms. i.e., phosphorus.
