van der Pauw method for measuring resistivity of a plane sample with distant boundaries

In the paper, we derive an algorithm which follows from the original van der Pauw’s technique for measuring resistivity with the added advantage of allowing contacts to be positioned a distance away from the boundary. For a large sample area, we show that the resistivity calculated by our algorithm is equivalent to the resistivity calculated by the original van der Pauw’s method. In practice, this configuration is easier to achieve and can eliminate errors associated with contacts that are not placed exactly at the edge.
