Аннотация
The longitudinal ρxx and Hall ρxy resistances were measured in the region of the quantum phase transitions for the quantum Hall effect regime with magnetic fields up to 12 T at temperatures of T = 0.4–30 K in two-dimensional electron systems n-In0.9Ga0.1As/In0.81Al0.19As. The nonuniversal scaling behavior of the temperature dependence of the width of the resistance ρxx peaks related to the effect of the large-scale random potential and of Landau-level mixing with opposite spin directions was found.
