The Correlation between the Energy Gap and the Pseudogap Temperature in Cuprates: The YCBCZO and LSHCO Case

Table 1

The critical temperature, the pseudogap temperature, and the values of the pairing potentials and for the YCBCZO and LSHCO superconductors. In the case of YCBCZO, the hole density () has been calculated based on the expression [23]. Let us note that for the superconductors, which do not show the in-plane disorder, it has been obtained: and . In the opposite case, the values of the parameters and increase together with the increasing disorder [24].
