Fabrication of Carbon Nanoparticle Strand under Pulsed Arc Discharge

Nowadays, carbon-based nanomaterial application on nanoelectronic is growing fast. Therefore, the nanoparticle fabrication as a device, needs to be optimized. In the present work, a pulsed AC arc discharge apparatus is fabricated for production of carbon nanoparticles (CNPs)-based device, which is derived from decomposition of methane gas in plasma condition and atmospheric pressure controlled by a bobbling system. The morphological properties and identification of synthesized CNPs are characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and nanofocus techniques. The analysis of obtained images confirms the existence of CNPs (mainly carbon nanotubes CNTs) in this method. Also, pulsed electric field equation and relation between growth time and distance between two electrodes are investigated. Moreover, growth conditions of CNPs and their physical mechanism are discussed. Finally, the current-voltage (I-V) characteristics of synthesized CNPs are examined.
