Minority and Majority Charge Carriers

In a P-type semiconductor the number of holes is larger than the number of free electrons in the conduction band. Therefore, in p-type material, holes are majority carriers and electrons are minority carriers. However, in an n-type material the number of free electrons in the conduction band is much larger than the number of holes. Thus, in an n-type semiconductor, electrons are majority carriers and holes are minority carriers.
