Abstract
The growth of ZnO nanorods based on an ion complex transformation method and a polymer carbonized grid backbone localization nanowire growth mechanism was introduced in this paper. We reported a preparation of the self-assembling [0001] oriented zinc oxide nanorods grown on Si substrates by using polymer as complex medium. A polymer solution containing ligands Zn/sup 2+/ via complexing the homogenous polar radicals in polymers with Zn/sup 2+/ ions in semiconductor metal salts was distributed evenly on Si substrates by coating. Then Zn/sup 2+/ transforms into ZnO quantum nanospots by oxidization. All the polymers were removed after chemical oxidization and only the carbon grid backbones remained that confine the ZnO nanorod's diameter. The ZnO nanorods have been characterized by FE-SEM, XRD and EDX. The diameter of ZnO semiconductor nanorods varies from 20 to 90 /spl mu/m and the length up to 5 /spl mu/m. The possible growth mechanism for ZnO nanorods on Si (111) substrates has been discussed as well.
