Fractional quantization of the Hall resistivity in silicon metal-insulatorsemiconductor structures
Pudalov V. M. , Semenchinskii S. G.
Anomalies have been observed in components of the resistivity tensor in silicon metal-insulator-semiconductor structures. These anomalies correspond to fractional values of the Landau-level filling factor, ν = 4/3 and ν = 2/3.
