We reported a novel class of neuromorphic device, ion-gating reservoir, which can realize the edge of chaos state by ion-electron-coupled dynamics at solid electrolyte/diamond interfaces and achieve high performance reservoir computing. The research results were published online in the American scientific journal Science Advances on December 15, 2022 (Japan time). Furthermore, a related article appeared in the Nikkan Kogyo Shimbun (print and electronic versions) on December 27, 2022.

NIMS postdoctoral researcher Roda-san leaves the group

A small farewell get-together was held for Dr. Nur, who has been working as a postdoctoral researcher in our group since October 2021. Prior to assuming the post-doctoral researcher position, she continued her research activities in our group through the NIMS Internship Program and NIMS Joint Research Hub Program. Dr. Nur will return to the U.S. to work in the private sector. Roda-san, we wish you a greater career ahead!!

Ms. itoh leaves the group after 14 years of working in our group

Ms. Itoh is leaving NIMS after being with the group for 14 long years since April 2008. She worked as a NIMS Special Researcher and a technical staff to support our group's research work. Even if hte place of work changes, we hope that her smile will remain the same. Thank you for your many years of support, Itoh-san.

research work by DR. tsuruoka et al. was selected as 'OPTICS RESEARCHES OF JAPAN IN 2021'.

Research work by Dr. Tsuruoka et al. published in Nano Letters has been selected as 'OPTICS RESEARCHES OF JAPAN in 2021' by 'KOGAKU', the Japanese Journal of Optics issued by the Optical Society of Japan. An introductory article titled 'Edge Detection Based on Materials-Intrinsic Properties - Ionic devices that mimic lateral inhibition of retinal neurons' was published in the June 2022 issue of KOGAKU. KOGAKU is the first Japanese-language journal on optics and photonics.

The ambassador of Italy to Japan, Gianluigi Benedetti paid a courtesy visit to NIMS

On Tuesday, April 19, 2022, H.E. Ambassador Gianluigi Benedetti, together with the Attaché (Science and Technology) Prof. Enrico Traversa, visited NIMS. After meeting with the President Hono and Executive Vice President Sasaki, they visited some laboratories in both Sengen and Namiki sites, including our laboratory. Group Leader Dr. Terabe gave a slide show on atomic switches and neuromorphic devices.


Grants-in-Aid for Scientific Research (KAKENHI) has been awarded to Dr. Tsuchiya for his research project. (Research theme: Development of solid state ionics-based physical property tuning devices and investigation on the interface functions; Collaborators: Kazuya Terabe (MANA PI) et al.) .
