- 論文の詳細を見る
Electrostatic carrier doping using a field-effect-transistor structure is an intriguing approach to explore electronic phases by critical control of carrier concentration. We demonstrate the reversible control of the insulator–metal transition (IMT) in a quasi-two-dimensional (2D) electron gas at the interface of insulating SrTiO3 single crystals. Superconductivity was observed in one device doped far beyond the IMT, which may imply the presence of 2D metal–superconductor transition. This realization of a quasi-two-dimensional metallic state on the most widely-used perovskite oxide is the best manifestation of the potential of oxide electronics.
