We study several widely used superconductors, both single-elements and compounds. We show that ion irradiation increases normal-state resistivity in all our films, which is expected to enable tuning their superconducting properties, for example, toward a higher kinetic inductance. We observe an increase in superconducting transition temperature for Al and MoSi and a decrease for Nb, NbN, and TiN. In MoSi, ion irradiation also improves the mixing of the two materials. We demonstrate the fabrication of an amorphous and homogeneous film of MoSi with uniform thickness, which is promising, for example, for superconducting nanowire single-photon detectors."}],"publication_identifier":{"eissn":["2166-532X"]},"title":"Effect of ion irradiation on superconducting thin films","month":"07","date_updated":"2024-07-16T06:33:11Z","acknowledgement":"We thank J.
