“…Fan et al found that the carrier confinement and charge separation at the interface in C/BN nanotubes are highly determined by the build-in electric field and band discontinuities. , The transition property of the C/BN nanotubes depends on the connecting pattern, which significantly influences the static first hyperpolarizabilities . Negative different resistance and large rectifying behavior were observed in the C/BN nanotubes with certain compositions and joint configurations. − …”

Carbon-doped boron nitride nanostructures including nanosheets, nanoribbons, and nanotubes have drawn enormous research attention because of their tunable electronic properties and widespread applications. In this work, we explore the electronic and magnetic properties of graphene flake-doped singlewalled boron nitride nanotubes (BNNTs) on the basis of first-principles calculations. Theoretical results reveal that the band structures of these doped BNNTs can be effectively engineered by embedding graphene flakes with different sizes and shapes. Moreover, the Lieb theorem works for the triangle graphene flake-doped BNNTs, and the corresponding doped systems are ferromagnetic, originating from the spin-polarized interface states. All BNNTs embedded with the triangular graphene flakes with relatively small sizes are typical bipolar magnetic semiconductors, which can be easily tuned into half-metals by carrier doping, opening the door to their promising applications in spintronic devices.

“…ε(ω), μ(ω), χ(ω), and κ(ω) represent frequency-dispersive permittivity, permeability, Tellegen, and chirality parameter, respectively. The macroscopic and effective material parameters of chiral media [36][37][38][39][40][41][42] are controlled by the physical geometric structure, material, angle of incidence, and so on. A purely chiral medium is discussed in this paper, in which case χ = 0.…”

“…They are namely: pure chiral medium equivalent to dispersive material, artificial chiral medium composed of helices etc., and natural chiral medium, such as DNA molecules. Although most natural and artificial chiral materials are passive, Boron Nitride NanoTubes [37,38], whose tube chirality distribution is determined by electron diffraction, are predicted to be used as gain media for phonons generation [39]. Besides the chiral multifunctionalized large molecules [40] and chiral metamaterials [41,42] with large optical rotation are potential active chiral materials.…”

We report a mechanism to obtain optical pulling or pushing forces exerted on the active dispersive chiral media. Electromagnetic wave equations for the pure chiral media using constitutive relations containing dispersive Drude models are numerically solved by means of Auxiliary Differential Equation Finite Difference Time Domain (ADE-FDTD) method. This method allows us to access the time averaged Lorentz force densities exerted on the magnetoelectric coupling chiral slabs via the derivation of bound electric and magnetic charge densities, as well as bound electric and magnetic current densities. Due to the continuously coupled cross-polarized electromagnetic waves, we find that the pressure gradient force is engendered on the active chiral slabs under a plane wave incidence. By changing the material parameters of the slabs, the total radiation pressure exerted on a single slab can be directed either along the propagation direction or in the opposite direction. This finding provides a promising avenue for detecting the chirality of materials by optical forces.

“…Moreover, theoretical studies suggested that in the case of B − C − N ternary tubular structures, it is the C atoms (rather than B and N) which act as dopant atoms in BN nanotubes. Therefore, the electronic properties of BN nanotubes [1,33,39,41,56,82,86] can be modified by the concentration of C atoms along with their atomic distribution. Carvalho et al [68] demonstrated that B3C2N3, BCN, and B5C2N5 nanotubes could be as stable as BC2N tubes, depending on the atomic distribution.…”

In this work, we study the structural and electronic properties of CX(BN)Y nanotubes, varying the CX concentration in the BN base structure. The developed work was done combining semiempirical, density functional theory (DFT) and Green’s function calculation methods. In the first part, we shown by structure energies that the distribution of B − C, C − N, C − C, and B − C chemical bonds greatly influence the structural stabilization of the nanotubes and the integration of the carbo (C) atoms within the CX(BN)Y systems has a strong dependence on the atomic distribution of B, C, and N atoms. In the second part, we shown that atomic distribution of B, C, and N atomos has also a strong impact on the electronic band gap, transforming the electronic structure of initial BN electronic configurations.
