| Research Abstract |
Transition metal oxides, having strongly correlated electron systems, show unusually drastic phase transitions(Mott transitions), including ferromagnetism, metal-insulator transition, and others. If it were possible to effectively control their carrier by electric field as semiconductor industry, novel fUnctional electronics could be created, I constmcted Fe oxide based field effect transistor/diode devices and realized electric field modulation of ferromagnetism and magnetoresistance at room temperature. Moreover, I originally developed ultra-small 3D oxide nano-structures, and discovered nano-stmcture enhanced electronic phase change in V-oxides, leading to further development of strongly correlated nano-oxide electronics.
