Two dimensional hexagonal boron nitride (2D h-BN) is a material of comparable structure to graphene with potential applications in e.g. photonics.,[1] fuel cells [2] and as a substrate for two-dimensional heterostructures.[3] 2D h-BN is isostructural to graphene, but where graphene is conductive, 2D h-BN is a wide-gap insulator.[3]
The properties of 2D h-BN films depends greatly on the quality of the films. It has been challenging to synthesize high-quality 2D h-BN over large areas.[3]
In particular, the small grain size of polycrystalline h-BN results in many grain boundaries, which create charge traps and higher surface roughness.
The production of 2D h-BN can be divided into top-down and bottom-up approaches. In bottom-up methods, a film is grown or deposited on a surface; in top-down methods, a larger structure is reduced until the desired state or structure is achieved.
