Abstract

Deviations from perfect quantization of the Hall resistivity rho(yx) at integer filling factors have recently been observed in Si metal-oxide-semiconductor field-effect transistors. We demonstrate how scattering between degenerate states at the edges in a quantum Hall system can lead to size-dependent deviations in rho(yx) from its quantized values. While the Hall resistivity fluctuates, the current flows without dissipation along the channel due to the absence of backscattering.
