Oxygen-vacancies_BiVO4

Different types of oxygen vacancies in bismuth vanadate (BiVO4) in the bulk (2x2x2 unit cell) and on the (001) surface (2x2x1 unit cell): Localized, vacancy-trapped states and split, V-O-V bridge forming states. Calculations were performed with GGA functionals PBEsol, PBEsol+U (U = 2.5 eV) and hybrid funcitonal PBE0-10 (PBE0 with 10 % of exact exchange).
