摘要：
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 ...
