The presentation will focus on inter-allotropic transformations/hybridizations of specific types that appear uniformly across large-area carbon networks, using moderate alternating voltage pulses. By controlling the pulse-magnitude, small-diameter single-walled carbon nanotubes can be transformed predominantly into larger diameter single-walled carbon nanotubes, multi-walled carbon nanotubes of different morphologies, multi-layered graphene nanoribbons, or structures with sp3-bonds. This re-engineering of carbon bonds evolves via a coalescence-induced reconfiguration of sp2-hybridizion, terminates with negligible introduction of defects, and demonstrates remarkable reproducibility. This reflects a potential step forward for large-scale engineering of nanocarbon allotropes and their junctions. |
