text: The next higher band is the conduction band, which is separated from the valence band by an energy gap.
text: The allowed bands are separated from each other by energy gaps (called forbidden bands), in which there are no electronic levels (Figure 1).
text: The next band is the conduction band, which is separated from the valence band by an energy gap (much larger gaps in crystalline insulators than in semiconductors).
