    Abstract: 本研究分為兩大部分,第一部分為在透明基材上製備抗反射陽極氧化鋁膜,探討不同陽極氧化鋁膜之參數在玻璃與藍寶石基材整體穿透率關係;第二部分則為使用50 nm 之自製陽極氧化鋁模板,並結合電化學沉積法製備出具有雙晶結構銅金屬線。
    ;There are two parts in this study. The first part is to fabricate antireflection anodic aluminum oxide (AAO) film on a transparent substrate, discussing the total transmittance relationship between glass and sapphire substrates with different parameters of AAO film; the second part is to fabricate Cu nanowires with twinned structures by combining the AAO template and electrochemical deposition technique.
    In this study, the total transmittance is determined by the effective refractive index and thickness of AAO film. The effective refractive index can be controlled by pore size, and the thickness can be controlled by the first anodizing time and etching time. As we obtain the optimal parameters, the total transmittance will be effectively promoted. Moreover, the pore of AAO film can be modified to the cone structure by repeated anodizing process and etching process, and we can obtain a moth-eye structure on AAO film. The total transmittance is significantly promoted by the gradual change of the effective refractive index in depth direction.
    On the other hand, we fabricate Cu nanowires with twinned structures by combining the AAO template and electrodeposition technique. The diameter of twinned Cu nanowires is about 50 nm, and the aspect ratio is up to 1200. Furthermore, we observe the density change of twins formed in the Cu nanowires under different experimental parameters and electrodeposition conditions by TEM analysis.
