Abstract
The temperature dependence of thermo-electric power (TEP) of Bi 2 Sr 2 Ca 1-x Ce x Cu 2 O y samples with x upto 0.4 are reported in the temperature range 40–300 K. The normal state TEP data of the superconducting samples are discussed in view of some of the existing theoretical models in the literature, viz. two-band models, Nagaosa and Lee model and a phenomenological narrow band model. The transport in the semiconducting sample is found to be by variable-range-hopping mechanism.
