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-Alx Ga1−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.
