摘要

利用溶膠凝膠模板技術結合電泳沈積方法及多孔陽極氧化鋁模板輔助成長BST奈米管及Au奈米線，成功製備出一維奈米電容器(Au/BST/Au奈米線)。
發現測試頻率、溫度及環境的相對溼度對其電容特性具有相當大的影響。頻率由100Hz至100KHz，電容變化量達到97%；溫度由20℃至80℃，電容變化量達到711%；相對溼度由20RH%至80RH%，電容變化量達到9643%，顯示出一維奈米電容器對頻率、溫度及溼度等三個主要因子的敏感性。

One-dimensional nanocapacitor (Au/BST/Au nanowire) has been successfully prepared by using sol-gel template EPD (electrophoretic deposition) method. Porous anodic alumina membrane was employed as the template for growing BST nanotubes and Au nanowires.
The measurement frequency, testing temperature, and relative humidity of the environment were found to have significant effect on the capacitance. The capacitance changes up to 97% when the measurement frequency increases from 100 Hz to 100 KHz. The capacitance changes up to 711% when temperature changes from 20oC to 80oC. The capacitance changes up to 9643% when the relative humidity changes from 20RH% to 80RH%. Base the present study, we have demonstrated that the measuremnet frequency, the temperature and the relative humidity are three major influencing factors for the capacitance of one-dimensional nanocapacitors.
