A method for resolution enhancement of scanning four-point-probe measurements on two-dimensional systems was presented. The resolution can be improved by a factor of approximately 50 to better than 1/15 of the four-point-probe electrode spacing by mapping the conductance on a dense grid around a target area and postprocessing the data. The results showed that the method can resolve the conductivity with submicron resolution.
