In some cases (e.g., when measuring an inhomogeneous doping process), one has to give up the advantages of the four-probe measurement, and the two-probe measurement ... the feed current and the applied voltage are meas- ured in only one pair of points. A correction factor between V / I and U is also needed. The pros and cons of the two-point measurem...
