Application

Monolayer hexagonal boron nitride (h-BN), also known as ″white graphene″, is a wide-bandgap 2D crystal (∼6 eV that can be tuned to ∼2 eV) with exceptional strength, large oxidation resistance at high temperatures, and optical functionalities. Among its potential applications are:
  • Two-dimensional electronics
  • Nanophotonic and other optoelectronic devices
  • Quantum communication and information science
  • Aerospace industry
  • MEMS and NEMS
  • Micro-/nano- actuators
  • Insulating/transparent coatings.

Storage and Stability

To ensure the maximum shelf life of your hBN sample, it is best stored under vacuum or in inert atmosphere (Argon or Nitrogen) conditions once the vacuum sealed package has been opened.

Atomic layers of hexagonal boron nitride (h-BN) crystal are excellent candidates for structural materials as enabling ultrathin, two-dimensional (2D) nanoelectromechanical systems (NEMS) due to the outstanding mechanical properties and very wide bandgap (5.9 eV) of h-BN. In this work, we report

Scientific reports, 7, 45584-45584 (2017-04-04)
Monolayer hexagonal boron nitride (h-BN) possesses a wide bandgap of ~6 eV. Trimming down the bandgap is technically attractive, yet poses remarkable challenges in chemistry. One strategy is to topological reform the h-BN's hexagonal structure, which involves defects or grain boundaries
