Outline of Final Research Achievements |
The aim of this study is to develop novel atomic film technology using 2D oxide nanosheets. Through first-principles materials design, we developed new conducting nanosheets (TiO2:F, MnO2:F) with high-electron mobility. We also discovered high-k oxide nanosheets (Ca2Nan-3NbnO3n+1) with the highest permittivity in the ultrathin region (< 10 nm). We utilized these nanosheets as building blocks in the LEGO-like assembly, and successfully developed various functional nanodevices such as all-nanosheet FETs, high-density capacitors, artificial ferroelectrics/multiferroics, magneto-plasmonic metamaterials, actuator crystals, etc. Our work is a proof-of-concept for creating new functional nanodevices beyond graphene and other 2D materials.
