Boron nitride: A new photonic material

Boron nitride: A new photonic material

Rhombohedral Boron Nitride (r-BN) layers were grown on sapphire substrate in a hot-wall chemical vapor deposition reactor. Characterization of these layers is reported in details. Xray diffraction (XRD) is used as a routine characterization tool to investigate the crystalline quality of the films and the identification of the phases is revealed using detailed pole figure measurements. Transmiss...

Hexagonal boron nitride for deep ultraviolet photonic devices

This paper provides a brief overview on recent advances in tackling the doping and optical polarization issues involved in the development of high performance deep ultraviolet (DUV) light emitting devices. In particular, recent developments in the exploitation of a novel DUV emitter layer structure based on a hexagonal boron nitride (hBN) and AlGaN p–n junction and doping engineering to potenti...

Design of photonic microcavities in hexagonal boron nitride

We propose and design photonic crystal cavities (PCCs) in hexagonal boron nitride (hBN) for diverse photonic and quantum applications. Two dimensional (2D) hBN flakes contain quantum emitters which are ultra-bright and photostable at room temperature. To achieve optimal coupling of these emitters to optical resonators, fabrication of cavities from hBN is therefore required to maximize the overl...

SYNTHESIS AND FUNCTIONALIZATION OF ATOMIC LAYER BORON NITRIDE NANOSHEETS FOR ADVANCED MATERIAL APPLICATIONS Besides graphene, hexagonal boron nitride nanosheets

SYNTHESIS AND FUNCTIONALIZATION OF ATOMIC LAYER BORON NITRIDE NANOSHEETS FOR ADVANCED MATERIAL APPLICATIONS Report Title Besides graphene, hexagonal boron nitride nanosheets (BNNSs) are playing an excellent role for the next generation of 2-dimentional (2D) functional nanomaterials. Due to the similar lattice parameter and identical crystalline structure to that of graphene, BNNSs are often kno...
