Question

Quizplus · Accepted Answer

The energy level diagram shown is for a semiconductor. Semiconductors have a band gap between the valence band and conduction band, as shown in the diagram. The diagram shows that the valence band is completely filled with electrons, while the conduction band is empty. This allows for the promotion of electrons from the valence band to the conduction band, creating mobile charge carriers and conductivity. Conductors have overlapping valence and conduction bands, while insulators have a large band gap and filled valence band. Isolated molecules and atoms can have discrete energy levels rather than continuous bands.
