Abstract

Measurements of thermoelectric power of BSCCO superconductors doped with Sb and Li at various concentrations are reported. The authors also report a calculation of thermoelectric power based on the marginal Fermi liquid hypothesis. The calculation is valid above the transition temperature in the temperature range where the superconducting fluctuations play no significant role. The measured TEP data fit the derived formula rather well in the above temperature range (which in this case is 130 K to 300 K). Using the fits, the basic parameters-such as Fermi energy and those involved in the marginal Fermi liquid hypothesis-are derived.
