Abstract: A low cost and substrate-independent method has been established to synthesize vertically aligned ZnO nanowires (NWs) on iron oxide films coated silicon substrates via low pressure Chemical Vapor Deposition (CVD) method at 650oC. In this study, Si substrates were dipped into the iron (III) nitrate nonahydrate solution prior to the synthesis process. This oxidized iron film facilitated the growth of highly oriented (002) ZnO seed layer, which allowed subsequent vertically aligned ZnO NWs to be grown on top of it during the synthesis. This approach has provided a good alternative to grow vertically aligned ZnO NWs without the need of considering the epilayer relationship between the ZnO and the material to be used as substrate.

Abstract: For any future cost-effective applications of inorganic nanostructures in particular hybrid photovoltaic cell, solution processable and selective printable of inorganic nanomaterials is essential. The patterning and growth of highly ordered arrays of crystalline ZnO inorganic nanostructures use simple soft lithography technique and mild reaction conditions; both low in temperature and free from harmful organic additives. Variable yet controllable anisotropic growth of ZnO nanowires has been demonstrated on the transferred patterns of ZnO nanocystals.
