Sia ? 4 years, 3 months ago

In a N-type semiconductor, the majority of charge carriers are free electrons whereas the holes are in minority. In a P-type semiconductor, the majority of charge carriers are holes whereas the free electrons are in minority. The donor energy level is close to the conduction band in the case of N-type semiconductors.
