In this study catalyst Fe nanoparticles of different sizes have been sputter deposited on Al2O3, ZrN thin film surfaces at different values of pressure so as to vary their sizes. Carbon nanotubes(CNTs) have then been grown on ZrN by Chemical Vapour Deposition(CVD) using acetylene as a source of carbon. The growth of CNTs on ZrN has been compared to their growth on Al2O3. It has been found that it is easier to grow CNTs on Al2O3 than on ZrN under the same conditions. Methods of promoting CNTs grown on ZrN have been investigated. The resulting nanostructures have been characterized by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Rutherford Backscattering Spectrometry (RBS). Such structures may find potential use in field emission displays and gas sensors.
