Abstract

The scaling theory of Anderson localization provides a comprehensive framework for understanding the transition between the localized and the extended states near the quantum Hall (QH) regime. Prior studies or measurements of the inelastic scattering exponent p in two dimensions, which plays a crucial role in quantum dephasing, mostly extract a magnetic-field-independent p spanning a wide range (1
