Interlayer Conductivity in the Superconductor Tl-Ba-Cu-O: Energetics and Energy Scales
A. S. Katz, S. I. Woods, E. J. Singley +5
We report on infrared studies of the c-axis electrodynamics of Tl-Ba-Cu-O (Tl-2201) crystals. A sum rule analysis reveals spectral weight shifts that can be interpreted as a kineti…

C-axis Josephson Tunneling Between YBCO and Pb: Direct Evidence for Mixed Order Parameter Symmetry in a High-T_c Superconductor
K. A. Kouznetsov, A. G. Sun, B. Chen +10
We report a new class of -axis Josephson tunneling experiments in which a conventional superconductor (Pb) is deposited across a single twin boundary of a YBa_2Cu_3O_{7-δ} cryst…
