Transmission electron microscopy of ZnO nanotube arrays etched from electrodeposited ZnO nanorods.
Well aligned large-scale ZnO nanorods were produced by a simple eletrodeposited process. Then, ZnO nanotubes arrays were formed via a subsequent etching in alkaline solution. Extensive studies including SEM, TEM, EDX, STEM and EELS indicate that the Zn and O elemental composition of the nanorods was well-proportioned along the whole cross section and the ZnO nanotubes were Zn terminated at (0001) polar surface toward the growth direction.
