Comparison of the hole concentration determined by transport measurement for the hole-doped cuprate superconductors

Abstract

We have compared the hole concentration (P pl ) determined by hole-scale based on the thermoelectric power at RT (S 290 ) to the hole concentrations (P) determined by two popular hole-scales based on the superconducting critical temperature (T c ) and Hall coefficient (R H ). While the hole concentrations based on different hole-scales are different, we show that when the P pl is divided by either the effective unit cell volume (V euc ) which is the unit-cell volume per one CuO 2 plane or the optimal hole concentration (P opt pl ) we can find some correlation between P pl and P. That is, the normalized T c (T c /T c (P opt pl )) and the Hall number (1/eR H ) are well scaled with P pl /P opt pl and P pl /V euc , respectively. We find that the P pl -scale can map to and reproduce the other two hole scales if proper dimensionality and normalization are taken into account but not vice versa.
