(2002)We study Josephson junctions formed at grain boundary interfaces in the high-Tc cuprate materials. The inherent properties of these Josephson junctions depend strongly on the pairing symmetry and the electronic structure ...
(1998)This thesis consists of three Chapters. In the first Chapter, based on a planar unconventional Fermi liquid model, we present several results on the optimally doped and overdoped cuprate superconductors. For the normal ...
(2004-05)The magnetic penetration depth λ of various unconventional superconductors have been measured down to ~0.1 K using a tunnel-diode based, self-inductive technique at 21 and 28 MHz. The samples measured are the heavy-fermion ...
Planar Tunneling and Andreev Bound State Spectroscopy of YBa2Cu3O7- d Thin Films Using Solution-Deposited Zirconia Insulators (2004-10)Planar tunnel spectroscopic measurements are performed on YBa2Cu3O7-δ (YBCO) thin films at four different crystallographic orientations. Since tunneling is a highly surface-sensitive probe on YBCO, films have been optimized ...
(2011-01-21)Despite record-setting performance demonstrated by superconducting Transition Edge Sensors (TESs) and growing utilization of the technology, a theoretical model of the physics governing TES devices superconducting phase ...
Vortex distributions and dynamics in superconductors near surface steps and sample edges studied by scanning SQUID microscopy and critical current measurements (2000)We have studied the interactions of vortices in superconductors with surface features and sample edges. Surface steps can generate an asymmetric vortex pinning potential and can influence the distribution of vortices upon ...
