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]. |
