Testing dielectric materials for areas of fluctuating current that affect their performance as superconductors.

Dielectrics are important for electronics technologies but areas of fluctuating current, known as two-level fluctuators (TLFs), in thin films can be a problem in certain applications. This research used lumped element resonators to find the distribution of TLFs in dielectric materials, which could be useful in improving the quality of superconducting devices.
