Scanning electron microscopy (SEM) plays an indispensable role in nanoscience and nanotechnology because of its high efficiency and high spatial resolution in characterizing nanomaterials Recent progress indicates that the contrast arising from different conductivities or bandgaps can be observed in SEM images if single-walled carbon nanotubes (SWCNTs) are placed on a substrate In this study

SEM image contains the surface information, including the topography, the material, and the local surface charge These three factors significantly affect the SE emission, as shown in Fig 1(b) The acceleration voltage, dwell time, and magnifi-cation are the most important parameters for SEM imaging The acceleration voltage determines the energy

Iijima's report 4 in 1991 brought carbon nanotubes into the awareness of the scientific community and triggered a deluge of interest in carbon nanotubes Shortly after this “rediscovery”, CNTs in different shapes (toroidal 5, coiled 6, 7, and branched 8, 9, 10) other than the straight were predicted theoretically Figs 1f-g show the illustrations of bent (kink) 11, branched 12, and coiled
