Abstract

A novel two-dimensional hexagonal V₂O was proposed and investigated through first-principles calculations. The hexagonal V₂O nanosheet exhibited a V-O-V sandwich structure. The stability of monolayer V₂O was verified by formation energy and phonon frequency calculations. The calculations of electronic properties using a hybrid density functional method indicate that monolayer V₂O is a nonmagnetic metal. However, the zigzag nanoribbon exhibited robust edge magnetism, while the armchair nanoribbon was found to be a nonmagnetic semiconductor with a direct band gap. The variety of electronic properties of monolayer V₂O nanosheets and nanoribbons opens up tremendous opportunities for nanoelectronic and spintronic devices.
