 Combining the two in various arrangements leads to a variable band gap which can be tuned by structure specifics to have various properties.Multi-walled carbon nanotubes when coated with boron nitride exhibit enhanced thermal activity compared to the substituents, but act as an electrical insulator.Graphene layers combined by boron nitride nanotubes exhibit similar band gap changes, but the strain of the ring position in the junction also induces a pseudomagnetic force on the ring structure due to the electron delocalization.
