Tailoring the properties of YBaCuO thin films by 30 keV He irradiation: An enabling route to superconducting device nanopatterning

Bernd Aichner, Simon Koch, Philipp A. Korner +8

Focused helium ion beam (He-FIB) irradiation with 30 keV ions is a key tool for nanoscale patterning and defect engineering in high transition temperature (Tc) cuprate superconduct…

Structural Changes and Transport Properties of Locally Modified by a He Focused Ion Beam

Ross Carter, Robin Hutt, Paul Zimmermann +9

Irradiation of a material with ions can cause various defects that can lead to structural phase transitions and the modification of the material's properties. Here we study the irr…

Dually tunable YBCO coplanar waveguide resonators based on helium-ion-generated Josephson inductances

Kenny Fohmann, Timo J. Glebe-Märklin, Benedikt Wilde +5

Superconducting microwave circuits with and without Josephson inductances are the Swiss Army knife for many experiments and technologies from quantum information science to astroph…

Non-volatile multi-state electrothermal resistive switching in a strongly correlated insulator thin-film device

Farnaz Tahouni-Bonab, Matthias Hepting, Theodor Luibrand +7

Strongly correlated insulators, such as Mott or charge-transfer insulators, exhibit a strong temperature dependence in their resistivity. Consequently, self-heating effects can lea…
