Which of the following statements is correct about p-type semiconductor and n-type semiconductor?

Which of the following statements is correct about p-type semiconductor and n-type semiconductor? Correct Answer Holes are the majority charge carriers in p-type semiconductors and electron are the majority charge carriers in a n-type semiconductor.

CONCEPT:

  • The material which is not a good conductor or a good insulator is called a semiconductor.
  • For example Silicon
  • The charge carriers which are present in more quantity in a semiconductor compared to other particles are called the majority charge carrier.


There are two types of semiconductors:

P-type semiconductor:

  • The semiconductor having holes as majority charge carriers and electrons as a minority charge carrier is called a P-type semiconductor.


N-type semiconductor:

  • The semiconductor having electrons as majority charge carriers and holes as a minority charge carrier are called as N-type semiconductors.


EXPLANATION:

  • From above it clear that holes are the majority charge carriers in p-type semiconductors and electrons are the majority charge carriers in an n-type semiconductor. So option 1 is correct.
