Two dimensional island arrays and honeycomb patterns consisting of ZnO nanocrystal clusters were fabricated on predefined TiO2 seed patterns prepared by vacuum free, aerosol assisted wet-chemical synthesis.The TiO2 seed patterns were prepared by applying an Enamel Pin US License Plate aerosol of a water soluble titanium complex on hexagonally close-packed polystyrene bead arrays for different lengths Fuse Tap of time.Scanning electron microscopy revealed that a dot array grows into a honeycomb shape as increasing amounts of the precursor were deposited.ZnO nucleation on substrates with a dot array and honeycomb patterns resulted in the formation of two discrete patterns with contrasting fill fractions of the materials.
