We studied electrical resistivity and the Hall coe cient of single-crystalline samples of an oxide superconductor Sr2RuO4 under hydrostatic pressures up to 1.2 GPa. The value of Tc decreases by 36 % at 1.2 GPa, while no appreciable change in the resistivity or the Hall coe cient has been observed. At room temperature an unexpected increase of resistivity along the c axis occurs with increasing ...

The electrical resistivity of Co/Ni and Cu/Ni superlattices exhibit resistivity oscillations as a function of superlattice period L, while Ag/Pd does not. Moreover, the resistivity of Co/Ni superlattices shows quantum size effects and a resistivity enhancement with L, as a function of total film thickness d . These results are consistent with a model which assumes d-electron localization in the...

The low-temperature electrical resistivity of corrugated semiconductor films is theoretically considered. Nanoscale corrugation enhances the electron-electron scattering contribution to the resistivity, resulting in a stepwise resistivity development with increasing corrugation amplitude. The enhanced electron scattering is attributed to the curvature-induced potential energy that affects the m...

This paper analyzes data taken by Gower-Hall for his MIT PhD thesis. In his thesis, Gower-Hall examines run-to-run control of epitaxial film deposition by way of thickness and resistivity measurements of the film deposited. Our main focus is analysis of the resistivity data captured from the experiments. We give an overview of the thesis, confirm Gower-Hall’s findings of the main factors influe...

The influence of the addition of carbon on the crystalline structure and resistivity of polycrystalline silicon layers grown by simultaneous decomposition of SiH,, C^H. a n d P H T a t '°"° c w a s studied. Carbon content, morphology, preferred orientation, crystallite size, lattice strains and resistivity were determined. It was found that carbon has a pronounced effect on the crystalline stru...

A central loop Transient Electromagnetic TEM Resistivity Survey was conducted at the Geysir high temperature geothermal area as part the project of the author. The area is situated 110 km away from Reykjavik and lies in a shallow valley elongated north-south. Geologically it is surrounded by three volcanic domes made-up of rhyolites, hyloclastites and inter-glacial basaltic lava that obtain hea...

We report magnetotransport investigation of nonmagnetic InSb single crystal doped with manganese at Mn concentration NMn ~ 1,5 × 10(17) cm(-3) in the temperature range T = 300 K-40 mK, magnetic field B = 0-25T and hydrostatic pressure P = 0-17 kbar. Resistivity saturation was observed in the absence of magnetic field at temperatures below 200 mK while applied increasing external magnetic field ...

Since the observation of the first brown dwarf in 1995, numerous studies have led to a better understanding of the structures of these objects. Here we present a method for studying material resistivity in warm dense plasmas in the laboratory, which we relate to the microphysics of brown dwarfs through viscosity and electron collisions. Here we use X-ray polarimetry to determine the resistivity...

This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated ‘wrapped’ and ‘naked’ burials were created. Multi-geophysical surveys were collected over a three-year monitoring period. Bulk ground resistivity, Electrical Resistivity Imaging, multi-frequency Ground Penetrating Radar and grave ‘soil...

Electrical resistivity evolution during precipitation in Al-Sc alloys is modeled using cluster dynamics. This mesoscopic modeling has already been shown to correctly predict the time evolution of the precipitate size distribution. In this work, we show that it leads too to resistivity predictions in quantitative agreement with experimental data. We only assume that all clusters contribute to th...
