| Outline of Final Research Achievements |
In this research, we demonstrated that a random network of gold nanoparticles functioned as a physical reservoir. Nanoparticle aggregates with 6 or 12 electrodes were fabricated using dielectrophoresis or multi-step immersion methods. The device properties at liquid helium and liquid nitrogen temperatures were evaluated through typical reservoir computing tasks such as waveform reconstruction and short-term memory. Our devices worked as ultra-small physical reservoirs that utilized nonlinearities due to the Coulomb blockade, and are expected to be applied to reservoir computing.
