The characterization of ZnO hybrid structure grown by metal-organic chemical vapor deposition |
초록 |
The growth of three-dimensional ZnO hybrid structures by metal-organic chemical vapor deposition was controlled through their growth pressure. Vertically aligned ZnO nanorods were grown on c-plane sapphire substrate at 600℃ and 400 Torr. ZnO film was then formed in-situ on the ZnO nanorods at 600℃ and 10 Torr. High-resolution X-ray diffraction and transmission electron microscopy measurements showed that the ZnO film on the nanorods/sapphire grew epitaxially, and that the ZnO film/nanorods hybrid structures had well-ordered wurtzite structures. The hybrid ZnO structure was shown to be about 5 μm by field-emission scanning electron microscopy. The hybrid structure showed better crystalline quality than mono-layer film on sapphire substrate. Consequently, purpose of this work is developing high quality hybrid epi-growth technology using nano structure. These structures have potential applicability as nanobuilding blocks in nanodevices. |
