...The electrical conductivity is perhaps the best indicator of the extent to which graphite oxide has been reduced to graphene.35 The electrical conductivity of the graphite oxide sheets and graphene nanosheets have been measured by the four-probe van der Pauw method which is often used to measure the Hall Effect.36 The sheet re- sistivity ( ) in Ohm meter of the sample can be calculated by where d is thickness of a thin film, R12,34 and R23,41 are two resistances measured when each of adjacent current and voltage contacts are switched, and f is a correction factor based on the ratio of R12,34 and R23,41....
