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, ΗУ пес, at least up to ρχχ=4χ 106 fl/Q The insulating phase was found to develop directly from at least three QHE phases at v= 1, 2 and 6, in contrast to recent theoretical predictions.
