Outline of Final Research Achievements |
Thin films and field-effect device structures of transition-metal oxides which show a first-order phase transition were fabricated with an aim of application utilizing strongly correlated electron materials. The electronic phase of vanadium dioxide was controlled in a nonvolatile by an electric field, which indicates a possibility of nonvolatile device application by controlling the electronic phase. Thin films of vanadium dioxide were fabricated on silicon substrates by controlling substrate temperature and oxygen pressure precisely during the deposition. The films exhibited a huge change in their optical properties.
