How electron is the minority charge carrier in a p-type semiconductor?
An “undoped” semiconductor has an equal number of electrons and holes. A semiconductor that has been doped to be “n-type” has had extra electrons added to it. Since there are now more electrons than holes, the electrons are the majority charge carriers and the holes are the minority charge carriers. A semiconductor that has been doped as “p-type” has essentially had extra holes added to it, so the holes are now the majority charge carrier and the electrons are the minority charge carriers. “Minority” and “majority” just refer to whether a semiconductor has more holes than electrons (p-type), or more electrons than holes (n-type).
