Abstract:
Through a catalyst-free chemical vapor deposition method, highly oriented ZnO nanowires and microtubes were simultaneously grown on the side and the top surface of Si substrate respectively. The ZnO nanowires and microtubes were characterized by scanning electron microscopy, X-ray diffraction, transmission electron microscopy and selected area electron diffraction. The growth mechanism of the microtubes was discussed and the room temperature photoluminescence properties of individual microtubes were investigated.
