Carbon in its elemental form or in various compounds has always been of huge interest within materials science and related research areas. The growth of carbon micro/nano-structures and thin films by employing methylene-iodide (CH2I2)as precursor has recently become of great interest. This molecule has low activation energy and therefore, can easily be dissociated pyrolytically or photolytically. The structured growth of carbon nano-tubes on hexagonal structure of catalyst particles via monolayres of polystyrene microspheres as mask, play a vital role in photonic crystals industry.
