Accurate defect levels obtained from the HSE06 range-separated hybrid functional

P Deák, B Aradi, T Frauenheim, E Janzén, A Gali - Physical Review B …, 2010‏ - APS
Defect levels are a problem for standard implementations of density-functional theory and
the error also influences the energetics. We demonstrate that the HSE06 functional, which …
