Tuning Kinetic Inductance with Doping in Superconducting Electron Gases at the KTaO (111) Interface.

We used coplanar waveguide resonators fabricated from the two-dimensional superconductor formed at KTaO (111) interfaces to characterize the superconductor's sheet kinetic inductance . Upon varying the carrier density, in samples with ranging from 0.62 to 1.
