【 摘 要 】

The incorporation of nitrogen into carbon nanotubes (CNTs) might increase their conductivity that can further enhance their excellent properties which is a very important issue nowadays. The current research focused on the fabrication of nanotube forests via catalytic chemical vapor deposition method and the investigation of nitrogen incorporation into carbon nanotubes on the surface of various substrates such as aluminum, titanium and silicon. Also, this study dealt with different catalyst layer deposition techniques in order to simplify the production of CNT forests. Besides, more complex layer construction methods such as pulsed laser deposition and dip-coating were also applied since they can influence the incorporation of nitrogen into carbon nanotubes as well. Samples were analyzed by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and Raman spectroscopy.
