Electrical transport properties of liquid alloys
Physics and Chemistry of Liquids, 2008The electrical transport properties namely the electrical resistivity (ρ), the thermoelectric power (TEP) and the thermal conductivity (σ) of several polyvalent alloys like In1−xBix and Sn1−xBix were calculated from the pseudopotential form factors and Percus-Yevic (PY) hard sphere structure factors of Ashcroft and Langreth.

Electrical transport properties of Ag3Sn compound
Solid State Communications, 2011Abstract The temperature behaviors of the electrical resistivity in polycrystalline Ag3Sn bulk samples were investigated experimentally. We found that the temperature dependence of resistivity shows concave function characteristics from 305 down to 26 K, and can be described by a parallel resistor model [H. Wiesmann et al., Phys. Rev. Lett. 38 (1977)

Electrical transport properties of YBa2Cu3Ox films
Solid State Communications, 1990Abstract Conductivity measurements are performed in polycrystalline superconducting YBa 2 Cu 3 O x films in an extended current density range (2 × 10 −3 - 400 A cm −2 ). At higher temperatures the resistivity versus temperature dependence is accurately linear, but both the resistance and its temperature derivative show large current effects when ...

Electrical transport properties of ZnO nanostructures
International Journal of Nanoparticles, 2009A physical vapour condensation method is used to synthesise the nanostructures of ZnO. These nanostructures are fabricated by resistive heating of Zn powder at a temperature of 400°C in the presence of oxygen and argon gases under a vacuum of order of 10−6 mbar.

Electrical Transport Properties of Glass
2019The aim of this chapter is to review the current understanding of various effects, both electronic and ionic transports, in oxide and chalcogenide glasses. Oxide and chalcogenide glasses are classified into an electronic or ionic transport materials depending on the composition of their constituents.

Electrical Transport Properties of Carbon Aerogels
Journal of Porous Materials, 2001Carbon aerogels are prepared by sol-gel polymerization and supercriticle drying. By controlling the mass ratio of reactants and the molar ratio of resorcinol to catalyst (R/C), carbon aerogels with different microstructure can be developed. Hall effect is measured by Van der Bow method.

Electrical transport properties of III-nitrides
Materials Science and Engineering: B, 1997Abstract Excellent n-type GaN layers have been grown by all of the major epitaxial techniques: MBE, MOCVD, and HVPE. In this work, we analyze the band conduction in such samples by temperature-dependent Hall-effect measurement and theory, and determine quantitative information on donor and acceptor concentrations, as well as donor activation energies.
