“…This similarity raises questions concerning the stability and material properties of graphene-like boron carbide 2D nanostructures. In general, graphene-like materials made from B, C and N show very attractive physical and chemical properties [46,47,48,49,50,51]. Interestingly, more than a decade before the synthesis of C 3 N nanomembranes [31], BC 3 layered sheets have been experimentally realized by Tanaka et al via epitaxial growth on NbB 2 surfaces [52].…”

Carbon based two-dimensional (2D) materials with honeycomb lattices, like graphene, polyaniline carbon-nitride (C 3 N) and boron-carbide (BC 3 ) exhibit exceptional physical properties. On this basis, we propose two novel graphene-like materials with BC 6 N stoichiometry. We conducted first-principles calculations to explore the stability, mechanical response, electronic, optical and thermal transport characteristics of graphene-like BC 3 and BC 6 N monolayers. The absence of imaginary frequencies in the phonon dispersions confirm dynamical stability of BC 3 and BC 6 N monolayers. Our first principles * Corresponding authors

Hexagonal BCN (h-BCN) is considered to be a promising dielectric ceramic material with a hybrid B–C–N structure and an electromagnetic wave (EMW) absorbing material with tenable properties. H-BCN bulk and microtube architectures are simultaneously synthesized by precursor pyrolysis method using BCl3, aniline (AN) and diethylenetriamine (DETA) as the raw material. By analyzing its electromagnetic parameters, the effective absorption bandwidth of the sample cracking at 900 °C with the proportion of raw materials (DETA:AN = 1:1) can be up to 7.2 GHz, and the minimum reflection loss can reach −43.6 dB at 7.92 GHz with a thickness of 3.5 mm. Moreover, the EMW absorbing property of the ceramic can be tuned by adjusting the ratio of monomers, pyrolysis temperature, and cooling rates.

The influence of hydrogenation on boron carbon nitride (BCN) thin films was investigated for low-k dielectric applications. The BCN thin films were deposited using radio-frequency magnetron sputtering in hydrogen, nitrogen, and argon ambiance. The hydrogen/nitrogen reactive gas flow was varied from 0/10 to 10/10 to achieve a varying range of hydrogen doping. Elemental composition and chemical bonding studies of the films were analyzed by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). XPS results confirmed the formation of B-C-N atomic hybridization, and FTIR confirmed the hydrogen doping by evidence of C–H bonds. Metal insulator metal structures were fabricated using Al and BCN thin films to measure electrical properties such as dielectric constant and resistivity. Hydrogenation of BCN caused a 68% decrease in the k value from 6.2 to 2 due to the formation of non-polar bonds. The k value of 2 reported in this study is the lowest value achieved for hydrogenated BCN films deposited by the RF magnetron sputtering technique.
