1. d-wave Josephson Junctions
Abstract : The properties of d-wave YBCO Josephson junctions and dc-SQUIDs with high misorientation angles have beenstudied experimentally .The predominant d-wave symmetry of the pairing wavefunction in high-Tc superconductors has, to a large extent, beena hinderance in applications, but it also makes it possible to fabricate devices with novel properties that may be suitablefor applications in the quantum regime; one particulary interesting property is a strong second harmonic component in the current-phase relation ofjunctions with the electrodes oriented in a node-lobe arrangement; so-called 0-45 junctions.

3. Symmetry, Disorder and the Josephson Effect in d-Wave Superconductors
Abstract : This thesis focuses on aspects of symmetry, disorder and the Josephson effect in d-wave superconductors which are generically characterized by sign changes of the gap function .DELTA.k in certain directions with respect to the underlying crystal lattice. READ MORE

5. Transport Properties of Superconducting d-wave junctions
Abstract : At surfaces and interfaces of d-wave superconductors, quasiparticle bound states with zero energy, midgap states (MGS), are necessarily formed as a consequence of the sign change of the d-wave order parameter upon 90° rotation. The MGS can never exist at s-wave superconductor surfaces and are therefore true fingerprints of unconventional superconductivity. READ MORE
