Temperature dependencies of R D , extracted from the I – V curves in a at I d.c. = 0 (blue), and the four-terminal longitudinal resistance R xx (orange). Above 50 mK, R xx deviates from zero, indicating that the dissipationless transport of the QAHE is lost. Consequently, the 2D bulk resistance eventually dominants R D at T > 100 mK.
