Characterizing dielectric properties of ultra-thin films using superconducting coplanar microwave resonators
Nikolaj G. Ebensperger, Benedikt Ferdinand, Dieter Koelle +3
We present an experimental approach for cryogenic dielectric measurements on ultra-thin insulating films. Based on a coplanar microwave waveguide design we implement superconductin…
Tunable superconducting two-chip lumped element resonator
Benedikt Ferdinand, Daniel Bothner, Reinhold Kleiner +1
We have fabricated and investigated a stacked two-chip device, consisting of a lumped element resonator on one chip, which is side-coupled to a coplanar waveguide transmission line…
Improving superconducting resonators in magnetic fields by reduced field-focussing and engineered flux screening
Daniel Bothner, Dominik Wiedmaier, Benedikt Ferdinand +2
We experimentally investigate superconducting coplanar waveguide resonators in external magnetic fields and present two strategies to reduce field-induced dissipation channels and…
