In p-type semiconductors, holes are situated in the valence band, not the conduction band. These holes are formed due to acceptor impurities, which create empty states in the valence band as electrons transition to the acceptor levels. The number of holes in the valence band exceeds the number of electrons in the conduction band, establishing a definitive characteristic of p-type doping.

In p-type semiconductors, electrons move from valence band to acceptor levels and hence empty states (holes) remain in the valence band.dwellexity said:where are the holes in the p-type semiconductor situated? in the conduction band or the valence band? i am talking about the holes formed because of the acceptor impurities, not the thermally generated ones.
