摘要：

Measurements made using two independent, high-precision systems on different samples of high mobility Si-MOSFETs have revealed unexpected irregularities in their i = 4 quantized Hall plateaus in spite of exceedingly low diagonal resistivities, 0.002 ppm of the plateau value. Relatively flat, metastable plateaus were observed which were offset by up to 0.4 ppm above the corresponding GaAs/AlGaAs value under the measurements at 14-14.5 T, 0.34-0.5 K with about 10-mu-A sample current. Possible connection of these phenomena with the offset plateaus observed by Kawaji et al. is discussed. At present no satisfactory explanation has been provided for these phenomena.
