Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

open access: yesSmall, EarlyView.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...
