Bandstructure of hexagonal gallium nitride (GaN)

The bandstructure calculation for gallium nitride was calculated using the program Quantum Espresso (version 5.2.1) and the pseudopotentials for Ga and N.

Annotation:
In this plot for gallium nitride you cannot readout the correct bandgap, but the form of the structure is right.
