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.

    press release: innovative transistors operated by magnetically induced movement of ions

    We have succeeded in developing a transistor in which an electrical conductance is tuned by an ionic movement induced by a magnetic field, instead of an electric field. The transistor - which does not require the application of voltage to operate - is potentially applicable to the development of energy-efficient information and communications devices with new functions . . .

    International Symposium on THE Atomic Switch: Invention, Practical Use and Future Prospects

    The atomic switch, which was developed in 2001 and jointly studied with the NEC Corporation with support from JST and MEXT, has been put to practical use as the ‘NEC AtomSW-FPGA’. At the symposium, it was explained that the NEC AtomSW-FPGA will be used in space satellites and that applications of the atomic switch are evolving into new, highly functional apparatus such as brain-type devices . . .

    Press Release: Various Organic Transistor Functions Created through Optical Drawing

    In a world's first, we succeeded in drawing one-dimensional transistor channels by scanning ultraviolet (UV) and visible (VIS) laser beams on thin films of photochromic molecules. These molecules can switch back and forth between one type of isomer that acts like an insulator and another type of isomer that acts like a semiconductor when they are exposed alternately to UV and VIS light. Our technique enables transistor channels to be re-written and their conductivity to be controlled, which opens up new possibilities for the development of optically reconfigurable, low-dimensional organic transistor circuits . . .
