In this project, we have studied the growth, morphology and surface characterization of metallized Carbon Nanotubes and conducted a comprehensive study on the application of this technology. Carbon Nanotubes are a tubular shaped isotope of carbon with unique physical, chemical and mechanical properties. In particular, we synthesized Carbon Nanotubes, using a RF-Powered Plasma Enhanced Chemical Vapor Deposition System. In this process, we used methane as the carbon source and high purity argon gas to create the plasma. The Silicon (Si)/Glass (SiO2) substrate was coated with a transition metal as a catalyst using both wet chemical means and Electron beam Evaporation.
After successfully growing Carbon Nanotubes, they were metallized with Iron (Fe) Nanoparticles using Physical Vapor Deposition System with an E Beam Evaporator. A comparative study between the metal coated and non coated Carbon Nanotubes was conducted. Possible applications such as use of this technology in synthesis of FET’s, use as Scanning Probe Microscope tips and other electronic applications are also discussed. A successful development in this field would have enormous applications in various fields and could lead to fabrication of miniature electronic components (in the order of nanometers).
