Technical Data | MSDS | Structure | Literature and Reviews

Hexagonal boron nitride (h-BN) (CAS number 10043-11-5) has a honeycomb structure based on sp2 covalent bonds similar to graphene. Due to the similarity it is also known as “white graphene”. Unlike graphene, h-BN exhibits a wide band gap due to the difference in electronegativities of boron and nitrogen.

h-BN is normally considered an insulator, and is used as a sub-layer material for any other 2D material in electronic devices. However, it has exotic opto-electronic properties (e.g. wide bandgap and low dielectric constant) along with mechanical robustness, high thermal conductivity and chemical inertness. It was later confirmed to have an indirect bandgap (at 5.955 eV), and thus is also considered a semiconductor. 

2D  h-BN has no absorption in the visible range, but has absorption in the ultraviolet region with good photoluminescence.

h-BN is widely used as a dielectric substrate in electronic and optical devices for graphene and other 2D-layered semiconductors (e.g. transition metal dichalcogenides TMDs).

Hexagonal boron nitride (h-BN) crystals are most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation. 

h-BN has been used as a protective membrane in devices such as deep ultraviolet and quantum photonic emitters, where it provides strong oxidation resistance. It has also been utilised as a tunnelling barrier in field-effect tunnelling transistors.
