Polycrystalline samples of Nd ( Sr 2-y Ba y)( Cu 3-x Mo x) O z (0 ≤ y ≤ 0.5, 0.1 ≤ x ≤ 0.3) with tetragonal structure were synthesized and investigated by powder X-ray diffraction, electrical resistivity, magnetic susceptibility and thermoelectric power measurements. Contrary to the absence of superconductivity of the Ba-free samples, superconductivity can be achieved by partially substituting Ba for Sr in semiconducting NdSr 2( Cu 3-x Mo x) O z (0.15 ≤ x ≤ 0.3). Thermoelectric power measurements reveal that all the samples are in the underdoped state and the partial substitution of Ba for Sr results in an increase of the carrier density on the superconducting layers.

High Degree

The temperature variation of the thermal conductivity, the electrical resistivity, and the thermoelectric power of a graphitized polyimide film have been measured in the temperature range 2 < T < 300 K. The effect of the electrochemical intercalation with FeCl4− ions has also been studied. The thermal conductivity measurements confirm the high degree of graphitization that may be obtained with polyimide films. They show how intercalation increases the structural disorder and how the intercalate substantially contributes to the thermal conductivity at low temperatures. The electrical-resistivity and thermoelectric-power measurements reveal that the density of free carriers is about three times lower in stage-2 FeCl4− solvated intercalation compounds obtained by an electrochemical way than in stage-2 FeCl3 compounds obtained by a classical synthesis method.

Power Measurements

Electronic structures of various kinds of alkali metal (Na, K, Rb or Cs)-doped C 60 solids are studied by electrical resistivity and thermoelectric power measurements by using C 60 single crystals prepared from a CS 2 solution as a starting material. For K-or Rb-doped C 60, metallic conducting behaviors in the normal conducting state and relatively sharp superconducting transitions are observed by the electrical resistivity measurements. Nearly linear-temperature dependences with the negative sign are observed in the thermoelectric power measurements at the normal conducting states for K-or Rb-doped C 60. From electron diffusion term of the thermoelectric power, the values of Fermi energy and the density of states at the Fermi energy are estimated by assuming the three-dimensional free electron model, which are in substantial agreement with the results of other experiments and calculations. "Metal–semiconductor transition" is observed in both the electrical resistivity and the thermoelectric power measurements for Na-doped C 60. Existence of metallic phase is confirmed by the thermoelectric power measurement in Cs-doped C 60.
