van der Pauw correction factor

The van der Pauw Method is a technique commonly used to measure the Resistivity and the Hall Coefficient of a sample. A correction factor goes into calculating the resistivity as described in van der Pauw paper. A iterative method is generally used to calculate the correction factor and this correction factor is plotted in Figure 5 of van der Pauw paper I reproduced the same figure below using fsolve function in octave. This figure was produced by the octave code shown below. The raw data is here. %This octave/matlab code calculates the correction factor,f as a function of Rmnop/Rnopm. This Read More …
