In an n-type semiconductor, which of the following statement is true?
Electrons are minority carriers and pentavalent atoms are dopants.
Holes are minority carriers and pentavalent atoms are dopants.
Holes are the majority carriers and trivalent atoms are dopants.
Electrons are the majority carriers and trivalent atoms are dopants.
An n-type semiconductor is created by doping an intrinsic semiconductor with pentavalent impurity atoms (such as Phosphorus, Arsenic, or Antimony). These pentavalent atoms donate extra electrons to the conduction band. As a result, electrons become the majority charge carriers, and holes become the minority charge carriers.
