Ionic nanoarchitectonics for electronics and artificial intelligence technology enhancement
Current Topics
We have developed an ALD technique that enables the uniform deposition of highly ionic conductive thin films into a three-dimensional structure. This technique is not only useful for fabricating thin films for all-solid-state batteries, but also for developing high-performance neuromorphic ionic devices for brain-like computing. [1].

Outline of Research
Information and communication equipment has achieved remarkable development through the technological development of electronic devices, represented by semiconductor devices. However, there are concerns about the performance limitations of semiconductor devices, which have been supported by ultra-microfabrication technology. Therefore, in order to overcome the performance limitations of conventional semiconductor devices, attention is also being paid to the development of new concepts for devices with various functions, such as brain-inspired devices. To develop such new devices, attention is being focused not only on electronics technology but also on ionic technology, or the fusion of electronics and ionic technology. We are developing ionic nanoarchitectonics methods that combine ionics and nanotechnology to create novel devices with a variety of unique functions and performances.
