In a n-type semiconductor dopant is pentavalent and electrons are majority charge carriers. However, a trivalent material is used as a dopant to obtain p-type semiconductor and holes are the majority charge carriers.

What is the difference between an n-type and a p-type intrinsic semiconductor?
Share
An n-type semiconductor is doped with elements like phosphorus, adding extra electrons (negative charge carriers). A p-type semiconductor is doped with elements like boron, creating “holes” (positive charge carriers) by missing electrons. Both enhance conductivity in intrinsic semiconductors but differ by dominant charge carriers: electrons in n-type and holes in p-type.
