| Outline of Final Research Achievements |
This research aims to demonstrate the effectiveness of "pore engineering." The present technique controls memory characteristics through (i) kind of added solvent, (ii) pore size, (iii) properties of the pore surface. In particular, in the metal oxide porous body CBRAM, our research revealed that the polarity and pH of the added solvent have a notable influence on the memory effect. In this study, many solvents for improving CBRAM performance were successfully developed. A significant improvement in the write/erase cycling endurance (SE) was realized, for example, by adding an ionic liquid containing Cu2+ or Ag+. The addition of a solvated ionic liquid makes it easy to approach Cu2+ to the cathode and the reduction of switching voltage as well as the improvement of SE was realized.
