Q.

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

In p-type semiconductor, an intrinsic semiconductor is doped with trivalent impurities, that creates deficiencies of valence electrons called holes which are majority charge carriers.
