Research Abstract

We aimed at understanding the basic physics behind oxide electronics and exploiting novel electric-field induced phenomena. An insulator to superconductor transition was achieved in two-dimensional electron system formed at the channel of SrTiO3 transistor. We also succeeded in visualizing conductive filaments, which were produced by reduction of base oxides, in resistive memories composed of binary transition-metal oxides. In heavy 5d Ir oxides with strong spin-orbit coupling, we discovered novel electronic phases such as spin-orbital Mott insulator.
