On the peak in the far-infrared conductivity of strongly anisotropic cuprates
A. Pimenov, A. V. Pronin, A. Loidl +2
We investigate the far-infrared and submillimeter-wave conductivity of electron-doped La_(2-x)Ce_xCuO_4 tilted 1 degree off from the ab-plane. The effective conductivity measured f…
Optical Cooper Pair Breaking Spectroscopy of Cuprate Superconductors
Y. G. Zhao, Eric Li, Tom Wu +8
The photon energy dependence of optical Cooper pair breaking rate (CPBR) is studied for compressibly strained La1.85Sr0.15CuO4 (LSCO) films and YBa2Cu2.92Zn0.08O7-delta (YBCZO) thi…
Possible pseudogap behavior of electron doped high-temperature superconductors
S. Kleefisch, B. Welter, M. Naito +3
We have measured the low-energy quasiparticle excitation spectrum of the electron doped high-temperature superconductors (HTS) Nd(1.85)Ce(0.15)CuO(4-y) and Pr(1.85)Ce(0.15)CuO(4-y)…
Anomalous Low Temperature Behavior of Superconducting Nd(1.85)Ce(0.15)CuO(4-y)
L. Alff, S. Meyer, S. Kleefisch +5
We have measured the temperature dependence of the in-plane London penetration depth lambda(T) and the maximum Josephson current Ic(T) using bicrystal grain boundary Josephson junc…
Observation of Bound Surface States in Grain Boundary Junctions of High Temperature Superconductors
L. Alff, A. Beck, R. Gross +6
We have performed a detailed study of the tunneling spectra of bicrystal grain boundary junctions (GBJs) fabricated from the HTS YBCO, BSCCO, LSCO, and NCCO. In all experiments the…
Superconducting NdCeCuO Bicrystal Grain Boundary Josephson Junctions
S. Kleefisch, L. Alff, U. Schoop +4
We have studied the electric transport properties of symmetrical [001] tilt NdCeCuO bicrystal grain boundary Josephson junctions (GBJs) fabricated on SrTiO bicrystal substrates wit…
