An interface is a boundary between two spatial regions either occupied by different matters or by matters in different physical states, for examples, solid-liquid and solid-solid interfaces. We are exploring solid-liquid interfaces to grow thin films of coordination networks via layer-by-layer approach. In so doing, spontaneous reduction of metal ion at solid-liquid interface is observed. As for the solid-solid interfaces, we are observing thermally driven resistive switching in thin films of coordination networks. Such phenomena are apparently arising at the solid-liquid and solid-solid interfaces – an interfacial effect. Notably, reduction of metal ion in liquid phase as well as resistive switching in solid phase are not taking place. Also, electrical rectification at the solid-solid interface was noted unlike in solid. Thin films were successfully employed for fabrication of electronic devices and for electro-catalysis catalysing oxygen reduction reaction. Our findings could provide new opportunities and challenges in advancing the concepts of chemistry occurring at various interfacial reactions.
All are cordially invited to attend.
