“…However, as shown in [21], the presence of S-W defects in graphene nanostructures significantly decreases their electrical and thermal properties. Previously, we have shown that FLG synthesized under SHS conditions from starch can be used as a cathode material for obtaining low-threshold field emission [22]. Based on the absence of S-W defects in FLG (see Table 1), it can be assumed that FLG can serve as a source of electrons.…”

It has been shown that defect-free Stone–Wales (SW) free few-layer graphene (FLG) can be obtained by carbonizing lignin under conditions of self-propagating high-temperature synthesis (SHS). The obtained few-layer graphene was used as a modifying additive for pyrotechnic compositions. It was found that the addition of 2.5 mass % of few-layer graphene synthesized from lignin to a pyrotechnic complex based on porous silicon and fluoropolymer leads to a significant increase in the combustion intensity of pyrotechnic compositions.

“…Although there are some synthesis methods for 2D borophene, finding a moderate way to controllably grow single-crystalline borophene sheets with high ambient stability remains a big challenge for the researchers all over the world. Both electrical transport and field emission properties are very essential for comprehending the intrinsic physical behaviors and mechanism of 2D materials. − However, until now, the research on the FE behaviors of borophene has not been carried out, perhaps because the as-grown borophene nanostructures have not enough high atmospheric stability or their in-plane dimension is not large enough for FE measurements, which inevitably inhibits the rapid development of borophene.…”

Being a typical graphene-like two-dimensional (2D) material, borophene has received a lot of attention due to its low density, high electron mobility, large Young's modulus, and good chemical stability. Compared with the corresponding bulk counterparts, 2D borophene has larger specific surface area, higher conductivity, and smaller work function, finding potential applications in high-speed transistors, optoelectronic detection, field emission (FE), and mechanical enforcement areas. In this paper, 2D tetragonal borophene sheets with high ambient stability have been successfully fabricated on the surface of 1 cm 2 copper foil using a developed low-pressure chemical vapor deposition (LPCVD) method. The vapor−solid mechanism was used to comprehend the formation of the tetragonal borophene sheets. The electrical conductivity of individual borophene sheets ranged from 4 to 5 × 10 −4 S/cm, and the band gap was about 2.1 eV, suggesting their narrow semiconductive nature. Also, the maximum FE current of individual borophene sheets was close to 1 μA, and their emission properties enhanced with the decreasing sheet thickness, comparable to many other nanomaterials with excellent FE performances. More interestingly, individual borophene sheets were found to retain good enough electrical transport and FE behaviors even if they experienced several days' atmospheric conservations. Our research results suggest that the LPCVD-grown borophene may be a promising building block for constructing high-performance nanodevices with good ambient stability.

“…To overcome these shortcomings, there is a need for a highly electrically conductive and robust material with a high ratio of electron emission sites. Recent studies believe that 1D nanostructures are suitable for higher quality PD. , Nanostructured materials such as graphene nanoribbons, carbon nanotubes (CNTs), , ZnO nanorod arrays, , and Si-nanofacets , have been investigated as potential cathode materials for PD. However, since the cathode material in plasma systems is constantly bombarded by ions, its stability becomes crucial.…”
