EFFECT OF SYNTHESIZING PARAMETERS ON MORPHOLOGY AND DIAMETER OF CARBON NANOTUBES GROWN BY THERMAL CVD METHOD

Carbon nanotubes were synthesized by thermal chemical vapor deposition method. There were parameters of the synthesizing process which influence the morphology and quality of nanotubes such as substrate material, the topology of substrates, the reduction process, and growing temperature. The topology of substrate affected the uniform of nanotubes. The reduction process using NH3 reductant helped reducing diameter of carbon nanotubes. Growing temperature complexly modified the quality of carbon nanotubes.
