    Often the dispersion relation is simplified to show just the bottom of the conduction band, and the top of the valence band. This simplification is useful because usually the density of states is sufficiently large in a bulk semiconductor that the gate is prevented from pushing the Fermi level into the band. Plots showing the band edges as a function of position are known as a band diagrams.

    Figure \(\PageIndex{1}\): An example of a band diagram. Here two insulators with different band gaps are connected. Note that the Fermi level must be constant in the two materials in equilibrium.
