For a p-type semiconductor, which of the following statements is true?

  1. A
    Electrons are the majority carriers and trivalent atoms are the dopants.
  2. B
    Holes are the majority carriers and trivalent atoms are the dopants.
  3. C
    Holes are the majority carriers and pentavalent atoms are the dopants.
  4. D
    Electrons are the majority carriers and pentavalent atoms are the dopants.

Solution & Step-by-step Explanation

p-type: Dopants are trivalent (Group 13) atoms like Boron, Aluminum, or Indium. These atoms have one less valence electron than Silicon, creating holes.Holes are the majority charge carriers.n-type: Dopants are pentavalent, majority carriers are electrons.
