Percolation-induced resistivity drop in lutetium dihydride with controllable electrical conductivity over six orders of magnitude [PDF]

open access: yesScience China Physics Mechanics and Astronomy, 2023
The recent report of near-ambient superconductivity in the nitrogen-doped lutetium hydride has attracted considerable attention. Subsequent follow-up studies confirmed the pressure-induced color changes in both N-free and N-doped LuH_2 but failed to ...

The Impact of Elongation on Change in Electrical Resistance of Electrically Conductive Yarns Woven into Fabric [PDF]

open access: yesMaterials, 2021
Electrically conductive yarns (ECYs) are gaining increasing applications in woven textile materials, especially in woven sensors suitable for incorporation into clothing. In this paper, the effect of the yarn count of ECYs woven into fabric on values of electrical resistance is analyzed.

Quantum conductance and electrical resistivity [PDF]

open access: yesPhysics Letters A, 2006
The Landauer formula for quantum conductance, based on the modern paradigm: "conduction is transmission", is generalized to samples of macroscopic size. Two regimes of electrical conduction, namely diffusive and ballistic ones, are studied. In the former regime, Drude's formula for the electrical resistivity is recovered and it is found a maximum ...

Measurement and Prediction of the Thermal and Electrical Conductivity of Al-Zr Overhead Line Conductors at Elevated Temperatures [PDF]

open access: yesMaterials Research, 2018
In the present work, the thermal conductivity and electrical resistivity of the Al-0.25 Zr (wt.%) alloy have been investigated from 300 K to 600 K. The variations of thermal conductivity (Ktotal) with temperature were measured by using a radial heat flow

Mapping the conductivity of graphene with Electrical Resistance Tomography [PDF]

open access: yesScientific Reports, 2019
AbstractElectronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene samples, obtained with a dedicated measurement setup and reconstruction software.
