“…: The domain sizes of CVD grown h‐BN were typically in the order of micrometer . Reducing the precursor feeding rate proves to be an efficient route to increase the domain size of h‐BN grown on Cu . We recently showed that when the partial pressure of the gas precursor decomposed from ammonia borane was lowered from 3 Pa to 0.4 Pa, the average domain size increased from less than 1 μm to larger than 20 μm on the inside surface of a Cu tube ( Figure a–c) .…”

Boron nitride (BN) structures are featured by their excellent thermal and chemical stability and unique electronic and optical properties. However, the lack of controlled synthesis of quality samples and the electrically insulating property largely prevent realizing the full potential of BN nanostructures. A comprehensive overview of the current status of the synthesis of two-dimensional hexagonal BN sheets, three dimensional porous hexagonal BN materials and BN-involved heterostructures is provided, highlighting the advantages of different synthetic methods. In addition, structural characterization, functionalizations and prospective applications of hexagonal BN sheets are intensively discussed. One-dimensional BN nanoribbons and nanotubes are then discussed in terms of structure, fabrication and functionality. In particular, the existing routes in pursuit of tunable electronic and magnetic properties in various BN structures are surveyed, calling upon synergetic experimental and theoretical efforts to address the challenges for pioneering the applications of BN into functional devices. Finally, the progress in BN superstructures and novel B/N nanostructures is also briefly introduced.

“…Variations in the chemical potential of constituent elements can occur experimentally when different processes and substrates are used or when the Cu substrates are subjected to a pretreatment (i.e., oxidation) (Zhang et al, 2016), as in this scenario. To date, several other experimental approaches to obtaining similar hexagonal-shaped domains have been reported (Stehle et al, 2015;Tay et al, 2016b;Wang et al, 2015a;Wu et al, 2015;Yin et al, 2015b). The coexistence of ZZ N and ZZ B edges is further verified by the observation of truncated triangular-shaped domains (Fig.…”

Monolayer hexagonal boron nitride (h-BN) is a phenomenal two-dimensional material; most of its physical properties rival those of graphene because of their structural similarities. This intriguing material has thus spurred scientists and researchers to develop novel synthetic methods to attain scalability for enabling its practical utilization. When probing the growth behaviors and structural characteristics of h-BN, the use of appropriate characterization techniques is important. In this review, we detail the use of scanning and transmission electron microscopies to investigate the atomic configurations of monolayer and bilayer h-BN grown via chemical vapor deposition. These advanced microscopy techniques have been demonstrated to provide intimate insights to the atomic structures of h-BN, which can be interpreted directly or indirectly using known growth mechanisms and existing theoretical calculations. This review provides a collective understanding of the structural characteristics and defects of synthetic h-BN films and facilitates a better perspective toward the development of new and improved synthesis techniques.

“…Group 15 monolayers become another kind of attractive twodimensional (2D) materials after graphene 1, 2 hexagonal BN, [3][4][5][6] and transition metal dichalcogenides, [7][8][9][10][11] due to their appropriate band gap and high carrier mobility. 12 Zhang et al 12 predicted that the group 15 monolayers, namely phosphorene, arsenene, antimonene, and bismuthene, exhibit high thermodynamic stability and show a broad range of band gap from 0.36 to 2.62 eV.…”

The one-dimensional nanoribbons have great potential applications in novel multifunctional electronic devices. Herewith, we investigate the electronic structure of antimonene nanoribbons using the first-principles calculations. Four ribbon models are considered. All of them are semiconductors with appropriate band gaps. Because of the loss of inversion symmetry, spin-orbit splitting appears in the asymmetric washboard nanoribbons. Significantly, spin splittings of 62 and 44 meV are found at the valence band maximum and conduction band minimum for zigzag asymmetric washboard nanoribbon (aW-zSbNR). Further applying an inplane electric field introduces a potential difference between the two zigzag edges. The energies for the localized edge states are modified. Eventually spin-orbit-coupling induced band inversion and electron-hole pockets with appropriately the same size could be triggered in a W-zSbNR, which is interesting for exploiting the magnetoresistance effect.npj Quantum Materials (2017) 2:15 ;
