Title Superconducting oxides interfaces
Abstract [For the full abstract see the attached pdf]. A key feature of these electronic systems lies in the possibility to control their carrier density by electric field effect, which results in gate-tunability of both superconductivity and Rashba spin-orbit coupling. In this talk, I will review complementary dc and microwave transport measurements conducted on SrTiO3 and KTaO3-based interfaces employing both back-gate and top-gate configurations. I will discuss, in particular, gate-induced multigap superconductivity [8,9] and the role of phase fluctuations within the Berezinskii-Kosterlitz-Thouless model [10]. I will also present the realization of field effect devices whose physical properties, including superconductivity and Rashba spin-orbit coupling, can be tuned over a wide range of electrostatic doping, and discuss the potential of oxides interfaces for the realization of mesoscopic devices [11].
