Oscillations following the Shubnikov-de Haas (SdH) formula are observed in the transition from the insulator to QH liquid when the observed almost temperature-independent Hall slope indicates insignificant interaction correction. Our study shows that the existence of SdH oscillations in such a transition can be understood based on the non-interacting model. © 2012 IOP Publishing Ltd.Electron systems; GaAs; Interaction corrections; Low magnetic fields; Magneto-transport measurement; Quantum hall; Quantum hall liquids; Shubnikov-de Haas; Magnetic fields; Quantum chemistry; Quantum Hall effect; article; chemical model; chemistry; computer simulation; electric conductivity; magnetic field; materials testing; methodology; oscillometry; quantum theory; radiation exposure; solution and solubility; Computer Simulation; Electric Conductivity; Magnetic Fields; Materials Testing; Models, Chemical; Oscillometry; Quantum Theory; Solutionsjournal article10.1088/0953-8984/24/40/405601229689552-s2.0-84866513626WOS:000309050700011
