Creating innovative nanoionic devices that will change the world

Our group aims to create nanoionic devices, based on nanotechnology and solid-state ionics, which enable a variety of new features that cannot be achieved with conventional semiconductor devices. In concrete terms, we utilize surface nanoarchitectonic local ion transport to produce interesting nano-phenomena resulting from physical or chemical actions. Further, by utilizing the characteristics obtained, we create nanodevices that operate based on new principles. Based on the basic research into the operating principles of these new nanoionic device, we are actively pursuing research on their practical use through collaborative research with allied companies. In addition, we are investigating novel methods for constructing molecular nano-systems, in which single organic molecules and single conductive polymers are connected to each other, and we are also developing methods for measuring the functions of such molecular nano-systems. Through such activities, we aim to demonstrate functional expressions of such devices as single molecule transistors and nanowire sensors, and to construct ultimately miniaturized single molecule device circuitries.
