Description

The correction factor F which is necessary to obtain resistivity by means of the four-point probe array located on the convex surface of a cylindrical material is investigated. Electric potential in a finite-length cylindrical material having a current source and a current sink is derived by solving Poisson's equation under various boundary conditions. The correction factor F is obtained using the potential. The resistance measurements are performed for isotropic graphite rods with different radius or different length. It is found from the experimental results that the correction factor F revises data accurately and yields a reasonable resistivity.
