In solid-state physics of semiconductors, a band diagram is a diagram showing the variation in the valence band and conduction band edges vs. some spatial dimension, often denoted x. The Fermi energy is also usually indicated in the diagram. Sometimes the intrinsic Fermi energy, Ei, which the Fermi level in the absence of doping, may be shown also. The work function and electron affinity are shown on some diagrams as well. These diagrams are useful in explaining the operation of many kinds of semiconductor devices.

Metals have an energy band diagram that is characterized by a small band gap between the valence and conduction bands. Metalloids, or semiconductor materials, are characterized by a moderate sized band gap, in which the Fermi level is located in the middle for a natural semiconductor. Insulators, or those compounds that involve nonmetals, have a very large band gap, so that electrons cannot escape the valence band to enter the conduction band.
