| Summary: | 碩士 === 國立臺灣師範大學 === 工業教育學系 === 101 === This study used 99.999% high purity aluminum foil through two steps anodization process making a high pore densities, ordering anodic aluminum oxide (AAO) templates. The various AAO pore diameters from 80 nm to 450 nm can be controlled well by controlling electrochemical sysyem and adjusting parameters such as applied voltage, electrolyte temperature and pore widening time, etc. AAO pore densities can be evaluated from 10^8 to 10^10 pore•cm^-2. Then, the single crystal of cesium iodide (CsI) sub-microwires were fabricated by liquid phase deposition method and thermal casting method. The mechanisms of this high aspect ratio and high densities structure and CsI sub-microwires forming were discussed and explained using the electrochemistry and thermodynamics.
