Fig. 8: Kohn-Sham electronic structure of various neutral SW-C defects in hBN.
From: Carbon-contaminated topological defects in hexagonal boron nitride for quantum photonics

Red and light blue lines depict spin-up and spin-down Kohn-Sham energy levels between the valence band and the conduction band (gray bars). The occupation of the defect states is indicated by filled and empty spheres. The electronic structure is obtained by using HSE(0.32) exchange-correlation functional.
