High reliability capacitors require a dielectric layer with both high electrical resistivity and high static dielectric constant. The most commonly used material platform for low cost, base metal electrode capacitors (BME) consists of nickel electrodes and barium titanate-based dielectric layers. Barium titanate (BaTiO3) is ferroelectric material with dielectric constant that depends on factors...

[1] Quantifying the spatial configuration of hydraulic conductivity (K) in heterogeneous geological environments is essential for accurate predictions of contaminant transport, but is difficult because of the inherent limitations in resolution and coverage associated with traditional hydrological measurements. To address this issue, we consider crosshole and surface‐based electrical resistivity...

We investigate the discontinuous ferromagnetic phase diagram near tricritical point in UCo1xRuxAl compounds by electrical resistivity measurements. Separation of phases in UCo0.995Ru0.005Al at ambient pressure and in UCo0.990Ru0.010Al at pressure of 0.2 GPa and disappearance of ferromagnetism at 0.4 GPa is confirmed. The exponent of temperature dependence of electrical resistivity implies chang...

The degree of dispersion of short microfibers in cement, as assessed by electrical resistivity measurement for the case of electrically conductive fibers at a volume fraction below the percolation threshold, is improved by the use of admixtures ~namely, silica fume, acrylic particle dispersion, methylcellulose solution, and silane! and fiber surface treatment ~such as ozone treatment!. Acrylic ...

The electrical transport properties of carbon nanotube/polymer composite films are investigated using temperatureand field-dependent resistivity measurements. By utilizing heatand chemical-based methods of cross-linking, it is possible to decrease the film resistivity by nearly 80% and modify the relative mobilities of electrons and holes, thereby altering the dominant carrier type in the films...

BACKGROUND We sought to compare uterine cervical electrical impedance spectroscopy measurements employing two probes of different sizes, and to employ a finite element model to predict and compare the fraction of electrical current derived from subepithelial stromal tissue. METHODS Cervical impedance was measured in 12 subjects during early pregnancy using 2 different sizes of the probes on e...

We study both the spin and electrical conductivities in models of relevance to the high Tc cuprates. These models describe metallic states with or without spin-charge separation. We demonstrate that, given a linear in temperature dependence of the electrical resistivity, the spin resistivity should also be linear in temperature in the absence of spin-charge separation and under conditions appro...

The electrical properties of ZnIn2Se4 thin films grown on glass substrates by the flash evaporation technique at different substrate temperatures (Ts) ranging from 473-623 K are studied. The influence of substrate temperature (Ts) on the electrical characteristics such as resistivity (ρ), Hall coefficient (RH), carrier concentration (ɳ), and Hall mobility (μH) of ZnIn2Se4 thin films were studie...

Out of plane vibrations are suppressed in graphene layers placed on a substrate. These vibrations, in suspended samples, are relevant for the understanding of properties such as the electrical resistivity, the thermal expansion coefficient, and others. We use a general framework to study the properties of the out of plane mode in graphene on different substrates, taking into account the dynamic...

Measurements of optical reflectance, transmittance, and electrical resistivity on the switchable mirror systems YHx and YDx show that the absorption of hydrogen induces the same variations as that of deuterium. In both cases there is a weak transparency window for the metallic dihydride (dideuteride) phase and a yellowish transparency in the insulating trihydride (trideuteride) phase. The sligh...
