High precision comparison of quantized Hall resistances
説明
Relative values of quantized Hall resistances R/sub H/(i) have been measured on the plateaus of i=4 and 2 for a GaAs/AlGaAs heterostructure device under the complete quantization condition and compared with each other. The value of 4*R/sub H/(4) differs appreciably from the value of 2*R/sub H/(2). This result suggests a possible deviation of i*R/sub H/(i) from the universal value h/e/sup 2/. >
