Description
Summary:Temperature dependences of thermoelectric power S(T) at \(T>T_c\) of the Hg-based high temperature superconductors Hg\(_{1-x}\)R\(_x\)Ba\(_2\)Ca\(_2\)Cu\(_3\)O\(_{8+\delta}\) (R=Re, Pb) have been analyzed with accounting for strong scattering of charge carriers. Transformation of parameters of a narrow conducting band in the region of the Fermi level was studied. The existence of correlation between the effective bandwidth and the temperature of a superconductive transition \(T_c\) is shown.
