“…[10] A large arsenal of the methods such as scanning probe microscopy (SPM), vibrational (Raman and IR) spectroscopy, X-ray diffraction, and scanning electron microscopy provides an access to the intrinsic characteristics of the carbon coatings, for example, the graphitization degree, roughness, and platelet sizes. [11][12][13][14] Most popular tools are both atomic force microscopy (AFM) and Raman spectroscopy, which provide information on the roughness and the chemical structure of carbonaceous coatings. [15,16] In the latter case, a ratio of two intense peaks G and D, assigned to the graphite mode (with symmetry E 2g ) at 1,590 cm −1 and the disorder-induced graphite mode (with symmetry A 1g ) at 1360 cm −1 , respectively, is used as a quantitative indicator of presence of crystalline and amorphous fractions in the resulting carbon layer.…”
