ChemInform Abstract
Cylindrical poly- and single crystalline Cu nanowires are produced by electrochemical d.c. potentiostatic deposition in polymeric ion track membranes from either an electrolytic Cu bath, or an aqueous solution containing CuSO4×5H2O and H2SO4. The samples are characterized by SEM and TEM. Polycrystalline needles are created at room temperature whereas at 60 °C single crystalline wires are obtained. The produced nanowires have diameters between 60 and 500 nm and aspect ratios of up to 500. Homogeneous large-density arrays of up to 109 wires/cm2 are produced on 8 cm2. The method enables the comparison of the influence of poly- and single crystallinity on transport processes in nanowires, for example the flow of electric current and propagation of sound waves.
