碩士 === 國立交通大學 === 電子工程系所 === 95 === In this thesis, 1D ZnO/TiO2 core-shell nanowires were prepared in two steps process. ZnO nanowires were fabricated by hydrothermal method at the low temperature as core. The ZnO nanowires were fabricated under the various solution concentrations and growth times of hydrothermal method in order to get a suitable ZnO nanowries array. TiO2 shell was deposited by sputtering method under the various sputtering time and power to get a uniform and different thickness. TiO2 tubes were fabricated by wet etching process. The optical properties, micro structure, surface morphology and the filed emission characteristics of ZnO/TiO2 core shell nanowires are studied. The structures after thermal treatment are also studied.
