Answer:

An N-type semiconductor is a type of material used in electronics. It is made by adding an impurity to a pure semiconductor such as silicon or germanium. The impurities used may be phosphorus, arsenic, antimony, bismuth or some other chemical element. They are called donor impurities.

____________________________________

  • n type semiconductor are formed by doping a pure Germany I'm or silicon crystal with pentavalent impurities to the atom.

or

  • N-type semiconductor is formed by adding small amount of pentavalent impurities to silicon or germanium material which acts as a base material.
  • the the pentavalent material is the one which has 5 valence electrons.
  • there are more numbers of electrons in compare of holes.
  • for example antimany, arsenic & phosphorus.
