Keywords:rhonbohedral boron sulfide, two-dimensional materials

Two-dimensional materials consisting of a single or a few layers of atoms have superior performance as compared to conventional materials or their bulk counterparts in a variety of applications. Combining 2D materials through layer stacking in a controlled manner can also produce several novel functionalities in the form of new three-dimensional layered materials (van der Waals heterostructures). Therefore, synthesis of new 2D materials opens several pathways for the applied use of van der Waals heterostructures. In this work, we have synthesized rhombohedral boron monosulfide (r-BS) based on the procedure reported in literature. We have then exfoliated the synthesized r-BS to form a new two-dimensional material of boron monosulfide. In the presentation, we will report on the results of X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, atomic force microscopy, Raman spectroscopy, and photo luminescence as well as the theoretical calculation results.
