Simple analytical method for determining electrical resistivity and sheet resistance using the van der Pauw procedure

Abstract

This work reports an analytical method for determining electrical resistivity (ρ) and sheet resistance (RS) of isotropic conductors. The method is compared with previous numerical solutions and available experimental data showing a universal behavior for isotropic conductors. An approximated solution is also reported allowing one to easily determine ρ and RS for samples either with regular or arbitrary shapes.

Anomalous behavior in high-pressure carbonaceous sulfur hydride

“…Pauw procedure [17] 𝜌 ≅ 𝜋𝑑𝑅 ln2 , (8) where 𝑑 is the thickness of the sample (5 − 10 μm) and 𝑅 is the measured resistance (1 − 2 Ω)…”

Magnetic field induced alignment of macroradical epoxy for enhanced electrical properties

“…For the sake of qualitative evaluation of electrical conductivity and mobility between samples prepared with magnetic alignment and without, we applied a recently demonstrated analytical solution for the VDP method. 46 where R s is sheet resistance in Ω/□, R 1 and R 2 are characteristic resistances between the pairs of four contacts in Ω , 47 and H 1 is a dimensionless geometric parameter, which can be expressed as; L 2 / L 1 is the ratio between the equivalent length and width of the conformal transformation of a sample with arbitrary shape into a particular parallelepiped sample.…”
