Frequency effect on Carbon nanotube growth by arc discharge method and its electrical characteristics

Devices incorporating carbon nanotubes (CNTs) offer exceptional electrical performance. The semiconductor CNTs, due to their various properties are useful for transistors especially field effect transistors (FETs) and Schottky barriers. This study presents our investigation about the effects of frequency on the growth of CNTs particularly multi walled carbon nanotubes and electrical properties of CNT-metal contacts. High voltage arc discharge is used for fabrication of CNTs for ohmic or Schottky contacts. Electrical properties were characterized by I-V curves after fixing frequency. It is observed that the conductivity of prototype carbon nanotube Schottky contacts alters under frequency modification.
