Three novel kinds of hierarchical ZnO nanostructures: nanocombs nanoscrewdrivers and nanonails, have been synthesized in large quantities via a simple thermal evaporation process in the same run of growth in different regions of the quartz tube. The morphologies could be well controlled by adjusting the distances between the source materials and the substrates. These ZnO products were investigated by scanning electron microscopy, X-ray diffraction and Raman spectroscopy. The field emission properties of the ZnO nanostructures were investigated. These hierarchical ZnO nanostructures may be attractive building blocks for field emission microelectronic devices and other devices.
