ZnO nanostructures are grown under a number of different conditions yielding a wide range of microstructures from “nano-stars”, “nano-caterpillars”, urchin-like structures to vertically aligned forests of hexagonal nanorods. For the nano-caterpillars, hexagonal crystals grow from the catalytic substrate allowing propagation of parent pillars, which subsequently form “daughter” rods propagating sideways from the faces.
