Physics - Semiconductors Question with Solution | TestHub

In a p-type semiconductor, trivalent impurity atoms are added, which act as acceptors. These acceptor atoms create a discrete energy level known as the acceptor energy level.

This acceptor energy level is located just above the valence band in the energy band diagram. Because it is very close to the valence band, electrons from the valence band can easily be thermally excited into the acceptor level at room temperature, leaving behind holes in the valence band which contribute to electrical conduction.

Answer: just above the valence band
