Abstract
It was revealed that a metalic nanodendrite with dendritic shape has catalytic activity. Therefore, the metalic nanodendrite is expected to be applied as a catalyst. An electrodeposition method has been used for fabrication of nanodendrite. However, this method has large environmental loads because it uses metal salt solution. Electrochemical migration that is called ionic migration (IM) is known as the phenomenon which causes insulation deterioration for electronic devices due to deposition of dendrite. Since this phenomenon occurs in the presence of moisture and DC bias, IM can be applied as a method for fabrication of dendrite with a lower environment load than the electrodeposition method. The purpose of this study is to show possibility of IM as a new method for fabrication of nanodendrite. In this study, a water-drop test was conducted to observe deposition process of Ag dendrite.
