摘要

We have synthesized novel diode-shape ZnO nanocrystals via a simple solid-vapor approach. This new nanostructure is constructed by two basic parts: a hexagonal nanorod and ultra-long nanowires on the two tips of the nanorod. The whole structure is a perfect single crystal along the [0001] growth direction with the length of a few 10 mm. This configuration is a new member in the family of Zno nanostructures. Based on our XRD and electron microscopy Study. the new effect of Sri in the growing process is discussed.
