Abstract:Quantum Hall effect provides the basis for primary resistance standard in electrical metrology. With discovery of new material and development of new technology, new progress is seen in quantum Hall resistance standard (QHRS). The development of QHRS is reviewed, starting from description of discovery of quantum Hall effect and its theory and universality, followed by introduction of GaAsbased and graphenebased quantum Hall devices and quantum resistance array, advantages of the new graphenebased QHRS and its development status are introduced, different types of resistance bridges, including direct current comparator, cryogenic current comparator and low frequency current comparator, are summarized, and development trend of QHRS is prospected.
