Abstract

We have investigated the nucleation and growth of single crystal ZnO nanowires on carbon films. ZnO nanostructures were grown on a transmission electron microscopy (TEM) grid consisting of a carbon film supported by a copper frame. No seed layer was used to provide nucleation sites. The resulting ZnO nanowires showed different diameters and lengths for growth on metal versus the carbon film. This is indicative of differences in nucleation and growth processes that depend on the substrate that was used. Our results indicate that ZnO nanowire arrays can be grown on carbon films by using a ZnCl2growth solution. This is a simple and low-cost method for growth of the nanowires. The method can also be used for investigating the mechanisms and morphology of ZnO growth on such carbon-based substrates. The growth of ZnO nanowires on carbon films, ribbons or nanodots has potential application for use in sensors, electronic, optoelectronic and photovoltaic devices.
