Answer Notes

P-type semiconductor material is created by doping a pure semiconductor, such as silicon, with a trivalent impurity like boron or gallium. This doping process creates a deficiency of one electron in the crystal lattice, which is commonly referred to as a "hole." These holes act as positive charge carriers. Because they vastly outnumber any free electrons present in the doped material, they are called the "majority" charge carriers. Distractors like free protons and free neutrons are incorrect because nuclear particles are bound in the nucleus and do not flow to carry electric current. Free electrons, on the other hand, are the majority carriers in N-type materials, not P-type.
