Resistivity, hall coefficient and thermopower in Mg70Cu30-,Zn (0 ⩽ x ⩽ 30) metallic glasses
Electrical resistivity. Hall coefficient and thermopower have been measured on Mg70Cu30-xZnx (0 ⩽ x ⩽ 30) ternary metallic glasses in the temperature range 77–800 K. We revealed that the resistivity and the Hall coefficient at 300 K exhibit a common feature in their composition dependences, but the thermopower behaves entirely in a different manner. By

Ceramic nickel-copper-manganite based negative temperature coefficient thermistors are unstable under thermal constraint, which increases the resistivity of these devices. This unstability can be reduced by the addition of a small amount of barium. These ceramics have a spinel structure, and the conduction takes place by a hopping process involving ...

Thermopower coefficient of pine-wood biocarbon preforms and the biocarbon-preform/copper composites
The thermopower S(T) of the composites prepared by filling empty sap channels in high-porosity biocarbon preforms of white pine wood by melted copper in vacuum and the thermopower S(T) of these preforms have been measured in the temperature range 5–300 K.

Heat capacity and thermopower coefficient of the carbon preform of sapele wood
This paper reports on measurements of the heat capacity at constant pressure Cp in the 80–300-K temperature interval and the thermopower coefficient S at 5–300 K of the carbon preform of sapele wood, which was prepared at the carbonization temperature of 1000°C. Measurements of Cp(T), our previous data on the phonon thermal conductivity, and literature

The temperature dependences of the thermopower coefficient for two systems of doped yttrium high-temperature superconductors Y1 − xPrxBa2Cu3Oy (x = 0.1−0.6) and Y1 − xCaxBa1.5La0.5Cu3Oy (x = 0.05–0.30) have been analyzed using three models of electron transport, i.e., the Xin two-band model, the two-band model with an additional term linear in ...

Measurements of thermoelectric effects such as the Seebeck effect, the generation of electric field in response to an applied thermal gradient, are important for a range of thin films and nanostructures used in nanoscale devices subject to heating. In many cases, a clear understanding of the fundamental physics of these devices requires knowledge of ...

Drift-diffusion contributions to the thermopower and Nernst–Ettingshausen coefficient of graphite
Abstract Drift-diffusion contributions to the thermoelectric power and Nernst–Ettingshausen effect have been calculated for graphite, using simplified models for the dispersion relationship ∊(k) and carrier relaxation time τ(∊). A comparison of the results with those derived from experiment on single-crystal and highly oriented pyrolytic graphite ...

Temperature coefficient of the resistivity and thermopower of pure liquid germanium: a new approach
We have recently published our experimental results on the resistivity () and on the absolute thermoelectric power (S) of liquid germanium. We complete the first paper by presenting improved theoretical calculations taking into account the generalized gradient approximation (GGA) with more recent exchange and correlation contributions.
