Abstract
Self-assembled hexagonal wurtzite ZnO rods network has been grown on Si (100) substrate by thermal oxidation of Zn powder at 600 °C with an oxygen flow of 100 sccm. The ZnO rods are found to be grown in a cellular network structure over a large substrate area in millimeter scale. They exhibit well-defined hexagonal facets with a diameter of ~ 200 nm and a length of ~2.5 μm and grow along ZnO b0001N direction mostly perpendicular to the substrate. Excellent luminescence properties of a strong UV emission peak with negligible green band have been obtained at room temperature.
