On the quantitative determination of hole-concentration in high-temperature cuprate superconductors

摘要: We compared four hole-scales that have been used to determine the hole-concentration in high-temperature cuprate superconductors. show hole-scale, Ppl-scale, based on thermoelectric power [T. Honma et al., Phys. Rev. B 70, (2004) 214517.] is quantitatively consistent with spectroscopic probes for many different materials, while other hole-scales, a well-known dome-shaped Tc-curve [M. R. Presland Physica C 176, 95 (1991)], c-axis lattice parameter [R. Liang 73, (2006) 180505(R).] and Hall coefficient [Y. Ando 61, (2000) 14956(R).], are not. resulted opposite conclusion of same experimental observations. It can also lead interpretations electronic phase diagram when comparing physical properties high-Tc systems. suggest Ppl-scale correct universal scale works all cuprates it should be quantitative doping dependence studies cuprates.
