The authors demonstrate a simple and fast method to grow ZnO nanorod arrays (NRAs) on patterned seed layer through low temperature solution growth. Spatial organization of nanorods was controlled by poly(methyl methacrylate) (PMMA) template patterned by nanoimprint lithography. For vertical growth of ZnO NRAs, the striped PMMA film placed above the ZnO seed layer restrained the growth of nanorods due to the inhibited contact between nucleation sites and nutrients. For horizontal growth of ZnO NRAs, postdeposition growth increases the diameter and length of the ZnO nanorods; thus improving the inter-rod connectivity of the self-assembled nanorods. The versatile all-solution manipulation of ZnO NRAs at low temperature using polymer templates patterned by nanoimprint presents a facile route toward practical electronic and optoelectronic applications of one-dimensional ZnO nanostructures. 2012 American Vacuum Society.
