• Rajasekaran et al. [77] found no difference between single- and few-layer graphene (both measured at 284.0 eV). On the other hand, Emtsev et al. [64] and Hibino et al. [73] measured the C 1s energy of mono- to few-layer graphene epitaxial on silicon carbide as a function of the number of layers, and found

• spectroscopy measurements were prepared by exfoliation of HOPG using a PDMS stamp and transferring them on SiO2 [42]. The number of layers was determined from the 2D peak of the Raman spectra, which was acquired prior to plasma treatment. An intermittent contact-mode AFM experiment was performed by means of a

• -resolution TEM images (Figure 1c and Figure 1d) show that the tubes have a different number of layers in each edge (for instance Figure 1c has four layers on the left, three on the right), suggesting that these are very likely hollow nanoscrolls, consistent with previous observations [11][32]. Characteristic

Presently there are increasing reports on the use of carbon nanotubes (CNTs) in electroanalysis [10]. CNTs may be multiwalled or single-walled depending on the number of layers of
