From touch screens to solar cells, sheet resistance is a key control characteristic for graphene films. The resistance varies by two to three orders of magnitude. However, even when made of the same thin film, the carrier mobility extracted from devices with different structures varies. The formulation of this document is conducive to standardizing the shape, electrode type, electrode contact method, and measurement of Hall devices of graphene films. The scientific nature of the graphene film quality evaluation system can be improved, and the influence of different experimental conditions on the measurement of carrier mobility and sheet resistance can be reduced. At the same time, the measurement method specified in this document is simple to operate, low-cost and has good economic benefits. Nanotechnology Sub-nanometer thickness graphene film carrier Mobility and Sheet Resistance Measurement Methods
