Fingerprinting seamless single-walled carbon nanotube junctions: Via the migration of encapsulated N<inf>2</inf>molecules from bottom to top: Are arrays of VA-SWNTs continuous?

© The Royal Society of Chemistry. Structure control such as diameter changes along single-walled carbon nanotubes (SWNTs) can be achieved in arrays of vertically aligned (VA-) SWNTs by switching the feedstock during growth. The local nature of the macroscopic transition from one diameter to another...
