Theoretical investigation on the structures, electronic and magnetic properties of new 2D/1D composite nanosystems by adsorbing superhalogen MnCl3 on the BN monolayer/nanoribbons

Abstract

Hexagonal boron nitride (h-BN), an inorganic analogue of graphene, possesses the remarkable physical and chemical properties and can be viewed as the powerful building block to construct novel composite nanomaterials. In this study, based on the first-principles calculations, we design a new class of hybrid nanosystems by depositing superhalogen MnCl3 on the surface of low-dimensional BN monolayer or nanoribbons (BNML/BNNRs). The large adsorption energies indicate that the MnCl3 can be stably adsorbed on the surface of the BN materials. Regardless of dimension, chirality, ribbon width as well as the adsorption site and coverage of MnCl3, adsorbing MnCl3 can endow these hybrid BN nanomaterials with a large magnetic moment and significantly reduce the robust wide band gap of BN materials to the range of 0.098–0.948 eV. Overall, these new MnCl3–BN composite nanostructures can display the large magnetism and an appropriate band gap, which is very promising to make them an application in the field of multifunctional nanodevices and magnetic materials in the near future.
