“…In this case, the maximum at Γ below the Fermi level is occupied by 2p (p x and p y ) states from oxygen, as happens in other ABO 4 compounds [40]. It has been reported that CBM of many rare-earth AVO 4 vanadates is dominated by vanadium 3d states, which makes these compounds present energy band-gaps close to 3.8 eV [50,51]. However, in the case of vanadates InVO 4 (phase II), CrVO 4 (phase II), and FeVO 4 (phase I), the energy band-gap lowers to 3.2, 2.6, and 2.1 eV, respectively, due to contribution from cation A to the valence and conduction band [5,6,50,52].…”
