Abstract:
The quantized Hall resistances, R/sub H/(4), of Si MOSFETs were measured at approximately=0.5 K in a magnetic field of 15 T. The value of R/sub H/(4) was determined in terms of the Commonwealth Scientific and Industrial Research Organization (CSIRO) realization of the SI ohm. A weighted mean of three determinations gave a value for the quantity R/sub H/(4) of (6453.203,36(52)) Omega /sub SI-NML/ which can also be expressed as 6453.2(1.000,000,52(8)) Omega /sub SI-NML/. This R/sub H/(4) value gives a value for h/e/sup 2/ which is about 0.3 p.p.m. larger than the value for h/e/sup 2/ derived from the anomalous moment of the electron, using the quantum electrodynamics (QED) theory.<>
