Probing Landau quantisation with the presence of insulator-quantum Hall transition in a GaAs two-dimensional electron system

Kuang Yao Chen, Y. H. Chang, C. -T. Liang +9

Magneto-transport measurements are performed on the two-dimensional electron system (2DES) in an AlGaAs/GaAs heterostructure. By increasing the magnetic field perpendicular to the…
