Monolayer hexagonal boron nitride (h-BN) is a geometric structural analog of graphene with sublattices substituted by boron and nitride atoms and with a stoichiometry of B and N being 1:1.

Hexagonal boron nitride (h-BN) has a layered structure. In a layer of h-BN, each boron atom is covalently bonded to three nitrogen atoms and vice versa. This creates a "honeycomb" or hexagonal lattice structure similar to that of graphene materials. Due to the similarity in structure, h-BN is often referred to as "white graphene".

Hexagonal boron nitride (h-BN) has emerged as a strong candidate for two-dimensional (2D) material owing to its exciting optoelectrical properties combined with mechanical robustness, thermal stability, and chemical inertness.

2016年1月25日 · Hexagonal boron nitride (hBN) exhibits unique electronic properties, such as a wide bandgap, low dielectric constant, high thermal conductivity and chemical inertness.

By first using Bellman and then expanding with Itô's rule, one finds the stochastic HJB equation.

2023年6月1日 · Hexagonal boron nitride (hBN) is an eminent thermally and chemically stable 2D (layered) inorganic material. The hBN is associated with many characteristics, such as excellent thermal stability, hydrophobicity and high surface coverage, increasing its usefulness and prominence as a nanofiller in polymer-based coatings.

Hexagonal boron nitride is an insulator with a band gap of ~6 eV and has been used extensively as an insulator for the production of ultrahigh mobility 2D heterostructures composed of various types of 2D semiconductors (e.g. WSe2, MoSe2, etc).
