Anomalous response of superconducting titanium nitride resonators to terahertz radiation
Anomalous response of superconducting titanium nitride resonators to terahertz radiation
We present an experimental study of kinetic inductance detectors (KIDs) fabricated of atomic layer deposited TiN films and characterized at radiation frequencies of 350 GHz. The responsivity to radiation is measured and found to increase with the increase in radiation powers, opposite to what is expected from theory and observed …
