Simone Frasca, a PhD student with from AQUA Laboratory, receives best student paper award from the 683rd WE-Heraeus-Seminar: Physics and Applications of Superconducting Nanowire Single Photon Detectors committee

Simone Frasca has been awarded for his work on the development of a practical method to measure the depairing current density of superconducting ultrathin films by means of superconducting nanowire resonators. By measuring the self-resonance of the devices fabricated in both amorphous (WSi) and polycrystalline (NbN) material systems, it is possible to measure the kinetic inductance dependence on the biasing condition of the device, enabling a precise estimate of the physical limit of the superconductivity in the film, which is the depairing current itself. The work was performed in collaboration with NASA Jet Propulsion Laboratory, Massachusetts Institute of Technology and the National Institute of Standard and Technology.
