Q158 / 160 · TS EAMCET 2022 (18 Jul Shift 1) · Physics

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

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

Solution

In p-type semiconductor, trivalent impurities are added to an intrinsic semiconductor, which creates holes which are majority charge carriers.

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