Boron nitride layers
WebIn terms of structure, α-boron nitride is comparable to graphite (therefore also called white graphite), and consists of a honeycomb-shaped, planar, hexagonal crystal structure in layers. Cubic β-boron nitride (CBN) as a modification of a boron-nitrogen compound has a cubic, diamond-like structure. WebWe investigate the electronic properties of ultrathin hexagonal boron nitride (h-BN) crystalline layers with different conducting materials (graphite, graphene, and gold) on either side of the barrier layer. The tunnel current depends exponentially on the number of h-BN atomic layers, down to a monolayer thickness. Conductive atomic force microscopy …
