Electrical Property Analytical Prediction on Archimedes Chiral Carbon Nanoscrolls

Silicon Doping Effect on the Electronic Behavior of Graphene Nanoscrolls

“…Therefore, SiCNS structures are stable enough for their potential applications. 23,24 To explore the electrical properties of SiC nanoscrolls, a single layer of doped graphene is considered, as shown in Fig. 1.…”

“…In chiral SiCNSs, the n and m integers of the chiral vector are not equal, and the chiral angle is between 0°and 30°, (0< a < 30). 23 Here, it is worth considering the difference between the boundary condition specified around the circumference of nanoscrolls and those applied in nanotubes (periodic boundary conditions). It has been widely reported that the basic model of the electronic structure of SiCNTs near the Fermi level is similar to that of a SiC sheet using a periodic boundary condition.…”

“…The distortion occurs as a result of interlayer interaction, the effects of boundary conditions or r-p rehybridization. 23 Considering the effect of boundary condition as the main reason, it is assumed that the energy eigenstates do not change greatly and that the boundary conditions only effect the orientation and position of k-lines near the Kpoints in a different way. Therefore, its effect is considered as a K-space quantizer, and the energy bands of nanoscrolls can still be studied from p and p* energy bands of graphene layers.…”

“…However, zigzag and chiral CNSs are mainly considered as semiconductors. 22,23 Although considerable research has been devoted to CNSs, rather little attention has been paid so far to studying the electrical properties of SiC nanoscrolls.…”

Boron nitride nanoscrolls: Structure, synthesis, and applications

“…Amongst the aforementioned dimensionalities, of utmost importance and largely underexplored are boron nitride nanoscrolls (BNS); flat boron nitride nanosheets (BNNS) rolled into a spiral-like morphology with a 1D scroll structure, and consisting of hollow cores with a unique open-ended morphology, and offering a large surface to volume area (see Figure 2a). Essentially, BNS are structural analogs of carbon nanoscrolls (CNS) [44][45][46][47][48], possessing exotic physiochemical properties that are strikingly dissimilar in electrical and insulating properties to CNT [49], and CNS [50][51][52], i.e., in contrast to CNTs, the electrical properties and band gap of BNS is independent of their chirality [53]. Also, BNS offer tunable interplanar distance by intercalation or doping making them a strong candidate for application in hydrogen storage, mass manipulation, and targeted drug delivery [54][55][56][57].…”
