1. 1. Approaching the depairing critical current in superconducting YBa2Cu3O7−x nanowires

   Författare :Shahid Nawaz; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; YBCO; Superconductivity; HTS; Nanowires; NanoSQUIDs;

   Sammanfattning : The microscopic origin of High critical Temperature Superconductivity isstill an open issue in condensed matter physics. In these complex oxideselectrons self-organize in ways qualitatively different from those of conventionalmetals and insulators. LÄS MER

3. 2. YBCO nanowires to study nanoscale ordering in High-Tc Superconductors

   Författare :Riccardo Arpaia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoscale ordering; nanoSQUIDs; nanowires; High-Tc superconductors; ultrathin films; oxygen doping; nanowire-based single photon detectors;

   Sammanfattning : We present the realization of YBa2Cu3O7-δ (YBCO) nanowires for both basic physics studies, which could help to elucidate the microscopic mechanisms of High critical Temperature Superconductors (HTS), and for novel applications.The first part of the thesis describes an improved nanopatterning procedure, based on e-beam lithography in combination with an amorphous carbon mask and a very gentle Ar+ ion etching.
