Abstract
After a brief survey of theoretical concepts for the two-parameter scaling theory in the integer quantum Hall effect regime, a comprehensive set of early, recent and new experimental results on constructing scaling diagrams for conductance in 2D semiconductor structures, as well as in graphene is displayed. A comparative analysis of scaling diagrams obtained from experimental data with calculated ones is carried out.
