摘要：

We show that any critical transition region between two adjacent Hall plateaus in either integer or fractional quantum Hall effect is characterized by a universal "semicircle" relationship between the longitudinal and transverse conductivities xx, xy, provided the sample is homogeneous and isotropic on a large scale. This is demonstrated both for the phase-coherent quantum transport as well as for the incoherent transport. © 1994 The American Physical Society.
