Abstract

Metallic nature of multiwalled carbon nanotubes (MWCNTs) were modified using low frequency (50Hz) non-equilibrium plasma, which was generated separately by oxygen and nitrogen dielectric barrier discharge plasma (DBD) at atmospheric pressure. Its potential to behave as semiconducting behavior mainly in diode application was studied. The surface structure and electrical properties changes before and after treatments were analyzed by using X-Ray Photoelectron (XPS), and IV measurement (a two-point probe). The current–voltage (I–V) characteristics shows that Au/MWCNT-N2(12kV)/Al shows good rectifying behavior. This showed that, the nitrogen-containing group can modify the metallic nature of MWCNTs to semiconducting behavior. Since the I-V curves for Au/MWCNTs-N2(12kV)/Al has rectifying behavior similar to Schottky diode, the electronic parameters such as ideality factor, barrier height and series resistance of the device were extracted by using three methods and give good agreement between them.
