(a) Tapping mode AFM images of the GNP-CNT hybrid acquired in a liquid cell. (b) Raman image of multi-layer graphene (bI), single-walled carbon nanotubes (bII), and GNP-CNT hybrid materials (bIII), respectively. (c) and (d) TEM and HRTEM images of the GNP-CNT hybrid, respectively. The whiter boxes in (a) mark the locations of multi-layer graphene.
