Preparation and Characterization of Boron Monosulfide Nanosheets with Tunable Bandgaps

Abstract

We have recently reported a new two-dimensional material of boron monosulfide (BS) nanosheet. It was produced by the mechanical exfoliation of rhombohedral boron monosulfide (r-BS) synthesized by heating the mixture of amorphous boron and sulfur at 1873 K and 5.5 GPa. Experimental characterizations and density functional theory calculations revealed tunable band-gap of BS nanosheets as much as approximately 1.0 eV. These results are introduced in detail.
