The phenomenology related to the growth of fullerene and graphene based nanostructures leads to a varied morphology, which depends critically on growth conditions. How to control this morphology through technology is a task requiring an exploration of new ways and modification of widely extended technologies like the classical chemical vapor deposition. In this presentation, we take a walk through a series of results achieved in our research group, with the intention of ordering in some way the many graphene and fullerene forms found and the CVD based technologies used. The resulting morphology is extremely varied and critically dependent on the growing conditions like precursor nature, gas mixture, temperature, pressure, plasma, gas flow rate. Also, resulting morphology depends on substrate nature and its structure, and surface morphology. We have explored different conditions and substrates like copper and stainless-steel foils, Cu/c-Si, Ru/c-Si, SiO2/c-Si, quartz, Cu/quartz, in order to find the carbon nanostructures characteristics more suitable for applications like electrodes, and planar sensors and devices.
