p-type majority carriers are holes

n-type majority carriers are electrons

In an N-type semiconductor, majority current carriers are electrons, while minority current carriers are holes. In a P-type semiconductor, majority current carriers are holes, while minority current carriers are electrons.

holes are majority in base

• bipolar devices use both majority and minority current carriers
• unipolar devices use only majority current carriers

The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
