What is Boron nitride?
Boron nitride is a non-toxic thermal and chemical refractory compound with high electrical resistance and is most commonly available in colorless crystal or white powder form. It is an advanced ceramic material often called "white graphene" or "inorganic graphite." In this article, Let's discuss the production, general properties, and uses of boron nitride. Boron nitride is a chemical compound of boron (B) and nitrogen (N) atoms. It exhibits excellent thermal conductivity and electrical insulation, widely used as filler in heat-dissipation resin sheets and substrates. Thanks to its smooth touch feeling and transparency characteristics, other applications, such as ingredients in cosmetics, are also being developed.
Pyrolytic Boron Nitride
PBN is a high-purity ceramic with excellent chemical resistance and high-temperature strength. Shin-Etsu Chemical succeeded in producing PBN domestically for the first time in Japan. PBN is used in crucibles to produce compound semiconductors and molecular-beam epitaxy, which use its characteristics. The extent of potential uses of PBN is expanding, and such services include high-functional PG/PBN heaters for semiconductor fields and CIGS-based thin film for photovoltaic power generation. (Basically, PBN products are custom-made.)
Hexagonal boron nitride is an indirect bandgap semiconductor
Hexagonal boron nitride is a wide bandgap semiconductor with high thermal and chemical stability in devices operating under extreme conditions. The growth of high-purity crystals has recently revealed the potential of this material for deep ultraviolet emission, with intense emission around 215 nm. In the last few years, hexagonal boron nitride has attracted even more attention with the emergence of two-dimensional atomic crystals and van der Waals heterostructures initiated with the discovery of graphene. Despite this growing interest and a seemingly simple structure, the fundamental questions of the bandgap's nature and value are still controversial. We resolve this long-debated issue by demonstrating evidence for an indirect bandgap at 5.955 eV using optical spectroscopy. We present the existence of phonon-assisted optical transitions, and e mean an exciton binding energy of about 130 meV by two-photon spectroscopy.
