| Abstract
| - A novel wet chemical technique for the site-selective growth of ZnO nanorod arrays on polymer substratesis described. Electron beam lithography is employed to define nanorod positions using a polymethylmethacrylate(PMMA) mask on a Kapton polyimide substrate with a Au intermediate layer. An applied potential is utilizedto enhance the nucleation process and achieve ZnO nanorods with a base diameter of 200 nm. The techniquedoes not require a ZnO seed layer and can be carried out at temperatures as low as 70 °C. Structuralcharacterization of the as-grown ZnO nanorods has been investigated by scanning electron microscopy andX-ray diffraction. This technique represents a new low-cost method for integrating ZnO nanorods into flexibleelectronic devices.
