| dc.description.abstract | Hexagonal zinc-oxide nanotetrapod structures were synthesised on p-type Si(100). Without using any catalysts, ZnO nanostructures were deposited on Si substrates using a simple Vapour-Liquid-Solid (VLS) process. The crystal structure and surface morphology of these ZnO nanocrystals which are tetrapods in shape; were studied using SEM and XRD methods. The XRD result revealed that the structure of ZnO is wurtzite and the crystallite size is 21.96 nm. UV-Vis measurements were carried out and it has been found that the absorption peak is at 380 nm and its bandgap is found to be 3.25 eV. It appears that they are of similar properties with near band edge emission at 437 nm (nearly) wavelength or at 2.83 eV. The SEM analysis shows the nanostructure formed on the substrate are nano-tetrapods, and the junction is nearly Y-shaped. | |
