| Abstract: | The quantum Hall resistance (QHR) standard based on GaAs needs to operate at a temperature of about 1.5K, which has many problems, such as high cost and complex operation.Graphene becomes the ideal material for the QHR standard as its unique properties are discovered and need only temperature of about 4.2K for the quantum Hall effect. Much effort has been spent in the application of graphene for the electrical metrology with great progress. Latest progress and still existing problems in the application of grapheme in QHR are summarized, future development trend is also presented. |
