2D Boron Nitride: Synthesis and Applications | …

Abstract Hexagonal boron nitride (h-BN), a layered material isostructural to graphite, has similar exotic properties like graphite. With single atom thick and alternating boron and nitrogen atoms in its atomic structure, h-BN is an insulator with band gap ~ 5.9 eV. As monolayer h-BN or boron nitride nanosheet (BNNS) has been studied for over a decade, a brief overview about the structure and ...
