Tailoring the morphology and wettability of ZnO one-dimensional nanostructures

Diverse one-dimensional (1D)nanostructures of ZnO, such as tower-like, conical, mushroom-like and ring-like, have been synthesized through vapor phase deposition method using metals and semiconductors as the substrates. SEM and TEM are used to characterize the morphologies and microstructures of as-synthesized products. Results indicate that the substrates have important effect on the morphology and structure of as-synthesized products. The growth mechanism of as-grown tower-like nanostructure is explained and the corresponding wettability is studied.
