Boron nitride is isoelectronic to carbon. As such, it shows strong similarities with solid state chemistry and physics of carbon, but the polarity of the B-N bonds yields for instance specific electrical insulation and chemical inertness. Intimately mixing boron nitride with carbon into the ternary B-C-N system could yield exquisite control of the transport properties, but full coverage of the composition map is unachievable at the moment, especially at the nanoscale where graphene-like “BCNs” could emerge. Overcoming this challenge and combining compositional control with nanostructuration could lead to innovative nanostructured “boron carbon nitrides” with unprecedented properties.
