| Outline of Final Research Achievements |
Structural analysis on interfaces between liquid metal (or molten metal) and solid materials is of practically importance for jointing different materials and developing composite materials. While atomic force microscopy (AFM) is known as a powerful technique for investigating liquid/solid interfaces, most of the AFMs use cantilevers as their force sensors, which requires optical detection system and they cannot applied for non-transparent liquid including liquid metal. In this study, we newly developed AFM for investigating in liquid metal. A quartz tuning fork sensor with a sharpened metal tip, where its deflection is electrically detected, was used as its force sensor. In addition, we modified the tip surface by a organic monolayer and a silicone-rubber holder for fixing the liquid metal droplet was developed. The surface of solid substrates were successfully imaged in liquid metal on the nanometer scale.
