Effects on van der Pauw' s resistivity and Hall coefficient measurement due to finite size contacts with selected shapes on a square sample were investigated. For the sheet resistivity measurement. For the sheet resistivity measurement, correction factors for the apparent measured values at zero magnetic field were determined from both electrolytic tank experiments and computerized.

The van der Pauw method is used to measure sheet resistivity and other properties of thin- films. It was first reported in 1958 by Leo J.
