Boron Nitride - an overview | ScienceDirect Topics
Boron nitride (BN) has different types of structural formation that relies in the lattice plan direction of boron and nitrogen atoms. The structures include amorphous, hexagonal, cubic, wurtzite form. Besides, boron nitride nanomesh, boron nitride nanotubes, and boron nitride aerogels are available for various biomedical applications (47).

Boron nitride nanosheets (BNNSs) have an identical crystal structure and similar lattice parameter to those of graphene sheets. However, growing quality BNNSs consisting of only several atomic layers remains a challenge. Here, we report on the synthesis of BNNSs at a temperature of 350 °C using a CO2 pulsed laser plasma deposition (CO2-PLD) technique by irradiating a pyrolytic hexagonal boron ...

We present an extended Tersoff potential for boron nitride (BN-ExTeP) for application in large scale atomistic simulations. BN-ExTeP accurately describes the main low energy B, N, and BN structures and yields quantitatively correct trends in the bonding as a function of coordination. The proposed extension of the bond order, added to improve the dependence of bonding on the chemical ...
