Boron Nitride an overview | ScienceDirect Topics

Boron nitride (BN), consisting of boron–nitrogen covalent bonds, was commonly used as a refractory material. Isoelectronic to sp 2 carbon lattice, BN was generally compared with carbon allotropes. The cubic form of BN (c-BN) has a diamond-like crystalline arrangement and the bulk crystal of h-BN is analogous to graphite crystal. 43 The 2-D sheets of h-BN are the most stable and soft among

Jan 21, 2021· Hexagonal boron nitride (hBN) is a layered dielectric material with a wide range of applications in optics and photonics. In this work, we demonstrate a fabrication method for few-layer hBN flakes with areas up to 5000µm2. We show that hBN in this form can be integrated with photonic microstructures: as an example, we use a circular Bragg grating (CBG).
