Coaxial cubic‐aluminum‐nitride–boron‐nitride composite nanotubes have been synthesized via a template‐free and catalyst‐free two‐stage route. The synthesized nanotubes have a uniform outer diameter of 50 nm and wall thickness of 15 nm, with a 2–3 nm thick BN coating. A vapor–solid (VS) mechanism is proposed for their growth, and insight is provided into the atomistic mechanism of coaxial nanotube growth.
