Outline of Final Research Achievements

To develop highly reliable metallic nanowire transparent conductive film, its behavior of electrical breakdown was clarified. Firstly, by using numerical analysis on temperature distribution of the metallic nanowire mesh under current stressing, the effect of boundary conditions on the electrical breakdown was clarified. Then, several fabricated metallic thin wires and wire meshes were employed to perform a series of current-stressing experiments, in which the effect of hot and humid environment was also clarified. Such results provide guidance to improve the reliability of metallic nanowire transparent conductive film, and therefore contribute the development of next-generational optoelectronics.
