What type of atom is needed as a dopant in a p-type semiconductor? atoms that have fewer electrons and protons than the semiconductor atoms being replaced atoms that have more electrons and protons than the semiconductor atoms being replaced O atoms that have fewer valence electrons than the semiconductor atoms being replaced atoms that have more valence electrons than the semiconductor atoms being replaced Why is it called p-type? The term p-type semiconductor means that this semiconductor is paramagnetic. O The term p-type semiconductor refers to the positively charged particles which are added to the semiconductor; in the result it is fully positively charged. O The term p-type semiconductor means that we use phosphorus as a dopant. O The term p-type semiconductor refers to the electron "holes" which can be viewed as positive areas in the sea of electrons.
