“…While in the case of synthesis at 50-60 min, an increase in the γ value up to ~2.5 of is observed. Thus, the obtained values of γ, which are rather close ~2.4-2.5, indicate diffusion processes associated with the morphological evolution of CNW films [25,28].…”

“…The value of α for the samples synthesized at 30,40,60 min is very similar and has a value of the order of ~1.2, while for the case of 50 min it equals to ~1.3. An increase in the value of α indicates a higher surface roughness [25]. Next, fractal analysis was performed using Power Spectral Density Functions (PSDF), corresponding results are presented in logarithmic scales in Figure 2b.…”

It is well-known that at the nano-scale, morphology can play a crucial role in the properties of nanomaterials and there is still a challenging task to control it during the synthesis. In this work, the morphology of carbon nanowalls (CNWs) is studied and evaluated on the basis of fractal analysis and Minkowski functionals. Synthesis of CNWs was carried out using ICP-PECVD method at different growth times. The obtained samples were examined using atomic force microscopy (AFM) with subsequent processing of the obtained data using the Gwyddion 2.55 program, which provides a fractal analysis including the height-height correlation function and the power spectral density function. The Minkowski functionals were plotted for evaluation of the morphology of the CNWs. The process of the formation of CNWs was considered depending on the synthesis duration. A possible time-dependent growth mechanism with certain stages of nanostructures formation is proposed. The correlation between the calculated parameters of morphology and the electrical properties of CNWs was revealed.
