CVD of Carbon Thin Films and Micro/Nano-Structures : Light Assisted Chemical Vapor Deposition of Carbon

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.
