Abstract :
A method allowing the comparison of quantized Hall resistances RH with an uncertainty of ∼4 × 10−9 is described. Results are presented for six heterostructures (five GaAs-AlxGa1−x As type and one InGaAs-InP type). The differences between the quantized Hall resistances RH(2) or RH(4) for four different GaAs-based samples are lower than ±5 × 10−9.
