Correlated electrons in vanadium oxides are responsible for their extreme sensitivity to external stimuli such as pressure, temperature or doping. As a result, several vanadium oxides undergo insulator-to-metal phase transition (IMT) accompanied by structural change. Unlike vanadium pentoxide (V3O3), vanadium dioxide (VO3) and vanadium sesquioxide (V3O3) show I MT in their bulk phases. In this study, we have performed one electron Kohn-Sham electronic band-structure calculations of VO3, V3O3 and V2O5 in both metallic and insulating phases, implementing a full ab-initio simulation package …
