Hall resistance and quantized Hall effect to insulator transitions in a. 2D electron system
Pudalov V.M., D'lorio M., Campbell J.W.,
The Hall resistance Rxy was studied deep in the insulating phase at the quantized Hall effect to insulator transitions in a dilute 2D electron system. While the diagonal resistivity pxx diverges, Rxy remains close to its classical value, Я/пес, at least up to pxx 4 χ ΙΟ6 Ω/Π. The insulating phase was found to develop directly from at least three QHE phases at и Η, 2 and 6, in contrast to recent theoretical preoUctions
