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…
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…
Temporal Evolution of Defects and Related Electric Properties in He-Irradiated YBaCuO Thin Films
Sandra Keppert, Bernd Aichner, Philip Rohringer +8
Thin films of the superconductor YBaCuO (YBCO) were modified by low-energy light-ion irradiation employing collimated or focused He beams, and the long-term sta…
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…
Why shot noise does not generally detect pairing in mesoscopic superconducting tunnel junctions
Jiasen Niu, Koen M. Bastiaans, Jianfeng Ge +10
The shot noise in tunneling experiments reflects the Poissonian nature of the tunneling process. The shot noise power is proportional to both the magnitude of the current and the e…
Temporal evolution of electric transport properties of YBCO Josephson junctions produced by focused Helium ion beam irradiation
M. Karrer, K. Wurster, J. Linek +4
Using a focused He ion beam (He-FIB) with a wide range of irradiation doses to we fabricated Josephson and resistive barriers wi…
