Visibility of hexagonal boron nitride on transparent substrates
Nanotechnology, 2020Abstract The high transmittance and low reflectance of monolayer hexagonal boron nitride (hBN) lead to its invisibility under white-light, causing serious troubles in the search, transfer, and fabrication of 2D material devices. In this work, we demonstrate enhancing the contrast of hBN on a transparent substrate by simulation and ...

Nitriding of iron boride to hexagonal boron nitride
Journal of Materials Science, 2000A process for preparing hexagonal boron nitride (h-BN) from iron boride (FeB) has been described for the first time. FeB powder was nitrided in ammonia at 700 K for 24 hours yielding non-crystalline BN and ζ-Fe2N. Subsequent annealing in ammonia for 1 hour at 1273 K resulted in a mixture of crystalline h-BN together with α-Fe, e-Fe3N and γ′-Fe4N.

Growth Mechanism and Morphology of Hexagonal Boron Nitride
Nano Letters, 2016Hexagonal boron nitride (h-BN) sheet is a structural analogue of graphene, yet its growth mechanism has been rarely studied, as complicated by its binary composition. Here, we reveal an atomistic growth mechanism for the h-BN islands by combining crystal growth theory with comprehensive first-principles calculations. The island shapes preferred by edge

Hexagonal Boron Nitride Nanophotonics
2019 Compound Semiconductor Week (CSW), 2019Hexagonal Boron Nitride (hBN) mono and multilayers are promising hosts for room temperature single photon emitters (SPEs) with excellent optical properties. In this work, we use high energy (~MeV) electron irradiation as a means to generate stable SPEs in hBN.

Preparation of Nanostructured Hexagonal Boron Nitride Powder
Journal of the American Ceramic Society, 2003In this communication, we describe an inexpensive and feasible method for the preparation of hexagonal boron nitride (h–BN) nanorods in the absence of metal catalyst. Tertiary calcium phosphate (Ca 3 (PO 4 ) 2 ...

Intrinsic ferromagnetism in hexagonal boron nitride nanosheets
The Journal of Chemical Physics, 2014Understanding the mechanism of ferromagnetism in hexagonal boron nitride nanosheets, which possess only s and p electrons in comparison with normal ferromagnets based on localized d or f electrons, is a current challenge. In this work, we report an experimental finding that the ferromagnetic coupling is an intrinsic property of hexagonal boron nitride ...

Photoluminescence Upconversion by Defects in Hexagonal Boron Nitride
Nano Letters, 2018Hexagonal boron nitride (h-BN) was recently reported to display single photon emission from ultraviolet to near-infrared range due to the existence of defects. Single photon emission has potential applications in quantum information processing and optoelectronics.

Boron-nitride nanotube triggered self-assembly of hexagonal boron-nitride nanostructure
Physical Chemistry Chemical Physics, 2014Molecular mechanics results show that a hexagonal boron nitride (h-BN) membrane can spontaneously assemble on the single-walled boron nitride nanotube (BNNT) in a scroll or helical manner, showing an interesting dependence on h-BN width.

Friction Dissymmetry on Hexagonal Boron Carbon Nitride
Nano LettersThe classical friction law posits that macroscopic friction is directly proportional to the normal force, represented by a constant friction coefficient. However, frictional behavior becomes increasingly complex at the nanoscale. We reveal a counterintuitive instance of dissymmetric friction during the sliding of a graphene flake on a hexagonal boron ...
