Abstract

original image

Arrays of ordered hollow urchin-like ZnO single-crystal nanowires with controlled core dimensions and wire morphology can be obtained by a new method that combines electrochemical deposition with colloidal templating rendered electrically conductive, as reported by Jamil Elias and co-workers on p. 1607. This method opens new opportunities for processing novel metal oxide or hydroxide materials based on a similar growth mechanism. Such ordered structures exhibit superior optical reflectance compared to nanowire arrays.
