Q134 / 180 · NEET 2013 (All India) · Physics

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

  • A
    Electrons are majority carriers and trivalent atoms are dopants
  • B
    Electrons are minority carriers and pentavalent atoms are dopants
  • Correct answer
    C
    Holes are minority carriers and pentavalentf atoms are dopants
  • D
    Holes are majority carriers and trivalent atoms are dopants

Solution

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

Hence, the correct answer is option: 'C'.
