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…
YBaCuO nano-constriction Josephson junctions and SQUIDs fabricated by focused helium-ion-beam irradiation
Christoph Schmid, Christopher Buckreus, David Haas +9
By focused He ion beam irradiation, epitaxially grown YBaCuO (YBCO) thin films can be driven from the superconducting to the insulating state with in…
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…
YBaCuO Josephson diode operating as a high-efficiency ratchet
Christoph Schmid, Alireza Jozani, Reinhold Kleiner +2
Using a focused He beam for nanopatterning and writing of Josephson barriers we fabricated specially shaped Josephson junctions of in-line geometry in YBaCuO thin f…
Vortex matching at 6 T in YBaCuO thin films by imprinting a 20 nm-periodic pinning array with a focused helium ion beam
Max Karrer, Bernd Aichner, Katja Wurster +9
Controlled engineering of vortex pinning sites in copper-oxide superconductors is a critical issue in manufacturing devices based on magnetic flux quanta. To address this, we emplo…
