Figure 3: Electronic band structure of MoS2 with sulfur vacancies.
From: Novel near-infrared emission from crystal defects in MoS2 multilayer flakes

Electronic band structures resulting from DFT calculations of models of MoS2 with concentrations of sulfur vacancies of (a) 2.1 atom% (1/48) and (b) 3.7 atom% (1/27). The zero of the energy axis is the Fermi level, that is, at midgap between the occupied and empty states. Note that the Brillouin zone is different in the two models, and thus the scale of the horizontal axis is different in the two panels.
