“…The length of our sample is 2 cm, the width is 5 cm and the thickness is 0.8 m. In Equation ( 6), σ is the conductivity of the sample, L is the length of the sample, S is the cross-sectional area of the sample, and dV dI is the resistance of the sample measured. [52][53][54] According to formula (6), the conductivity of the three composite films are 0.00212 S/m, 0.00222 S/m and 0.00236 S/m, respectively. Seeing Table S4 for specific values.…”

“…The band gap of BN nanotubes is about 5 $ 6 eV, so it is electrical insulated in electrical properties and is hard to be oxidized in chemical properties. [5][6][7][8] Tao et al found that the thermal conductivity of zigzag-edged BN nanoribbons is about 20% higher than that of armchair-edged BN nanoribbons, which proves that there is anisotropy in heat transfer in BN nanoribbons. 9 Leonardo et al combined density functional theory with Green's function, and proved that boron carbon nitrogen nanotubes (BCNNTs) with doping concentration more than 20% showed higher ZT.…”

In recent years, the thermoelectric properties of one-dimensional boron nitride nanomaterials have gradually attracted widespread attention of researchers in the world. In this paper, boron carbon nitrogen based composite nanofiber films were prepared by electrospinning. It is found that the diameter of nanofibers decreases in BCNNTs/PVA/PEDOT composite films when electrospinning voltage rises, while diameter increases as PVA and BCNNTs concentration increase of electrospinning precursor solution. Finally, thermoelectric power factor is investigated of the composite nanofiber films. It is verified that thermoelectric properties of the films closely related to electrospinning quality. However, fiber density of single-layer BCNNTs/PVA/ PEDOT nanofiber film is too low, folding increase the density and thickness of multilayer BCNNTs/PVA/PEDOT nanocomposite fiber films, and the thermoelectric characteristics are significantly improved. The Seebeck coefficient can reach 3.62 mV/K and the power factor is 29.09 nW/mK 2 .

“…The sp 2 -bonded hexagonal BN (h-BN) provides a 2D material, [6][7][8][9] which can be used in advanced electronic devices as an insulating film. [10][11][12][13][14] The sp 3 -bonded cubic BN (c-BN) has a diamond-like structure applicable to hardcoating films because c-BN 5,[15][16][17][18] is the second hardest material next to diamond. 19,20) In addition, c-BN coating films can be used in harsh environments, such as hightemperature gases and plasmas, owing to their thermally and chemically stable features.…”

Boron nitride (BN) films with a wide variety of nano-network structures (sp2–sp3 bonded) were prepared and their sputtering behaviors were investigated. BN films were formed using a reactive plasma-assisted coating technique. Fourier transform infrared spectroscopy (FT-IR) and nanoindentation analyses confirmed the presence of sp2- and sp3-bonded phases. Then, the thickness change by plasma exposure was studied for various BN films. Sputtered depth after the plasma exposure of the prepared BN films was lower than that of SiO2 films. While no clear change was observed in the FT-IR spectra after the plasma exposure, the leakage current and dielectric constant changed due to the surface modification. It was found that the modified layer underneath the sputtered surface contained the local defects which play a role as carrier trapping or hopping sites. The sputtering behavior analysis in combination with electrical measurements is a useful methodology for designing BN films.
