Abstract

This work presents the synthesis and characterization of two different zinc oxide (ZnO) nanowire assemblies: arrays of parallel-oriented cylindrical wires and three-dimensional (3D) networks of highly interconnected wires. Both are synthesized by electrochemical deposition in the pores of etched ion-track polycarbonate membranes. The crystallinity and crystallographic properties of the wires are influenced by the deposition parameters. In particular, we investigate how the diameter of the membrane nanopores and the deposition potential affect crystal orientation and morphology during nanowire growth. X-ray diffraction and energy dispersive x-ray analysis demonstrated that all wires are pure ZnO with a wurtzite hexagonal structure and free of impurities. The unique architecture of the synthesized 3D networks of nanowires with a high aspect ratio and enhanced mechanical stability is discussed.
