A Universal Intrinsic Scale of Hole Concentration for High-Tc Cuprates
T. Honma, P. H. Hor, H. H. Hsieh +1
We have measured thermoelectric power (TEP) as a function of hole concentration per CuO2 layer, Ppl, in Y1-xCaxBa2Cu3O6 (Ppl = x/2) with no oxygen in the Cu-O chain layer. The room…

Anomalous superconducting properties at magic doping levels in under-doped La2-xSrxCuO4 single crystals
F. Zhou, P. H. Hor, X. L. Dong +3
A series of high-quality under-doped La2-xSrxCuO4 superconductor crystals with x = 0.063 - 0.125 were prepared by traveling-solvent floating-zone (TSFZ) technique. We found by dc m…

The composite picture of the charge carriers in La2-xSrxCuO4 (0.063 < x < 0.11) superconductors
Y. H. Kim, P. H. Hor, X. L. Dong +4
Through far-infrared studies of La2-xSrxCuO4 single crystals for x = 0.063, 0.07, 0.09, and 0.11, we found that only ~ 0.2 % of the total holes participated in the nearly dissipati…
