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.

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