The structural, electronic, and magnetic properties of monolayer BN doped with 3D metal trioxide and tetraoxide superhalogen clusters are investigated using first-principle calculations. TMO3(4)-doped monolayer BN exhibits a low negative formation energy, whereas TM atoms embedded in monolayer BN show a high positive formation energy. TMO3(4) clusters are embedded more easily in monolayer BN than TM atoms. Compared with TMO3-doped structures, TMO4-doped structures have a higher structural stability because of their higher binding energies. Given their low negative formation energies, TMO4-doped structures are more favored for specific applications than TMO3-doped structures and TM atom-doped structures. Large magnetic moments per supercell and significant ferromagnetic couplings between a TM atom and neighboring B and N atoms on the BN layer were observed in all TMO4-doped structures, except for TiO4-doped structures.
