The calculated curves are aligned to the experimental data at T = 0 K after having applied the GW correction to the indirect gap. after having applied the GW correction to the indirect gap.
In solid state physics and related applied fields, the band gap, also called an energy gap or stop band, is a region where a particle or quasiparticle is forbidden from propagating. For insulators and semiconductors, the band gap generally refers to the energy difference between the top of the valence band and the bottom of the conduction band.
