THERMOELECTRIC-POWER OF HIGH-T-C OXIDE SUPERCONDUCTORS

Using the formula of thermo-electric power for the local pair model, b ased on the two-component model of high-T-c superconductivity, we stud y the experiments of thermoelectric power of several kinds of high-T-c oxide superconductors and find that this model can give a general exp lanation of the thermo-electric power phenomena of high-T-c oxide supe rconductors. According to the study of thermo-electric power of HgBa2C uO4+delta and HgBa2CaCu2O6+delta, we consider that the physical proper ties of underdoped and optimum doped samples are analogous, which are different from overdoped samples. The property of overdoped samples ap proaches to that of the conventional metal.
