PHOTOCONDUCTIVITY OF CARBON NANOTUBE OBTAINED BY ARC DISCHARGE METHOD

The Synthesis of Carbon Nano Tubes by Arc Discharge Method in Liquid media

In this investigation a simplified arc discharge apparatus was used to synthesize mullti-wall carbon nanotubes. Because of not requiring vacuum equipment, heat exchange system, active or inert gases, this method is found to be cheaper and simpler than traditional arc discharge in gas environment. Using this method, CNTs are produced by performing an arc discharge between two graphite electrodes...

Photoconductivity in single wall carbon nanotube sheets

In this paper we report for the first time, the photoconductivity of large area sheets of single wall carbon nanotube upon laser illumination. The photoconductivity exhibited an increase, decrease or even ‘negative’ values when the laser spot was on different positions between contact electrodes, showing a ‘position’ dependent effect of photoconductivity. Photon induced charge carrier generatio...
