ZnO nanorod periodic honeycomb-like arrays were fabricated via hydrothermal method on c -plane sapphire with ZnO seed layer prepared by radio frequency magnetron sputtering. The polystyrene (PS) microspheres with a diameter of 762 nm self-assembled monolayer (SAM) were employed as a mask to grow vertical and highly ordered ZnO naonstructures. The resulting ZnO nanorods with diameters of 20~90 nm are size tunable by changing the concentration of solution, the pH values and the surfactant. The structure properties of nanorods were characterized by x-ray diffraction (XRD), field-emission scanning electron microscope (FESEM) and photoluminescence spectra (PL). From XRD and FESEM measurement, the ordered ZnO nanostructure arrays show highly (0002) preferred orientation. The results suggested that the ZnO nanostructure arrays not only grow with high uniformity but also provide significant surface area. This structure is suitable as a template for high surface area nanocapacitor application.
