Carbon is one of the most investigated materials and shows chaotic behavior in processing of its various allotropic forms. To process carbon-related films in a variety of scale, their syntheses largely depend on the deposition technique, process parameters and ratio of the gaseous chemistry. Both chemical vapour deposition techniques, hot filament and microwave plasma, have been largely employed to deposit such films on different natured substrates in varying thickness, growth rates, size of grain or crystallite, morphology, structure and quality through abundantly available gaseous mixtures. In this study, carbon-related materials are synthesized in chemical environments and their development process has been explained in a new context. Here, we discuss the dynamics of atoms that manipulate the morphology-structure of films ranging from nano-meters to several microns under various process parameters. This study embarks on the unexplored science of carbon-related materials while depositing thin and thick films on differently treated substrates where amalgamation of atoms into tiny clusters, grains and crystallites depend on the process dynamics and manipulate their structure. Carbon atoms bind under their localized heating where elastically driven electronic states determine their charge dynamics. In two-dimensional lattice of carbon atoms, impinging electron streams (for certain period) stretch electronic shells of atoms in the direction of impingement and electronic shells overlap the next adjacent one of one-dimensional arrays under suitable localized heating of lattice (plastically driven electronic states), thus, transforming the lattice into smooth elements under the action of photons. Our model permits to predetermine the process parameters under which specific phase of carbon atoms is obtainable.
