Problem 4: Newton-Rhapson Method to determine resistivity Van der Pauw showed that the resistivity of an isotropic conductor can be measured by preparing a plane-parallel sample of arbitraty shape with four small contacts at arbitrary places A, B, C and D along the circumference (Philips Res. Repts 13, 1-9, 1958). The resistance RAB.CD is defined as the potential difference Vo-Vc between the contacts D and C per unit current through the contacts A and B. The current enters the sample through the contact A and leaves it through the contact B as shown in the figure below CD DA The resistivity (which has units of cm) follows from the values of the resistances R.B.CD and RBC.DA and the thickness h, which must satisfy the relation -rRAB.CDh A Van der Pauw measurement for resistivity was performed on a 700 nm thick Si-doped Gallium Nitride sample. The resistance values RAB,CD and RBCDA were measured as 440 and 95 , respectively. Write a MATLAB function which solves directly the Van der Pauw transcendental equation using the Newton- Rhapson method for any resistance value and then implement for the given resistance values to obtain a value for the resistivity with at least 3 significant digits. Employ an initial guess of 0.1 -cm
