The microwave-photoexcited high mobility GaAs/AlGaAs two-dimensional electron system exhibits an oscillatory magnetoresistance with vanishing resistance in the vicinity of magnetic fields B=[4/(4j+1)]Bf, where Bf=2πfm*/e, m* is an effective mass, e is the charge, f is the microwave frequency, and j=1,2,3… Here, we report transport with well-resolved Landau levels, and some transmission characteristics.

    We have measured the energy gaps in single-layer and bilayer graphene by means of temperature dependent transport experiments in high magnetic fields up to 33 T. They follow the expected Landau level splitting when a finite level width is taken into account. The quantum Hall effect, hitherto...

    At high magnetic fields, where the Fermi level lies in the N=0 lowest Landau level (LL), a clean two-dimensional electron system (2DES) shows numerous incompressible liquid phases which exhibit the fractional quantum Hall effect (FQHE; ref. ). These liquid phases do not break rotational...

    The physics of Dirac fermions in condensed-matter systems has received extraordinary attention following the discoveries of two new types of quantum Hall effect in single-layer and bilayer graphene. The electronic structure of trilayer graphene (TLG) has been predicted to consist of both...

    We have studied the quantum Hall effect in a parabolic well with two occupied subbands. The ringlike structure is found in the density-magnetic field phase diagram for longitudinal and Hall resistances. In addition we produce a tilt angle-magnetic field phase diagram, which also demonstrates a...

    The unique electronic behaviour of monolayer and bilayer graphene is a result of the unusual quantum-relativistic characteristics of the so-called ‘Dirac fermions’ (DFs) that carry charge in these materials. Although DFs in monolayer graphene move as if they were massless, and in...

    It has been pointed out that, according to the two-parameter scaling theory, the magnetic-field position of the phases of the integer quantum Hall effect (IQHE) at ωcτ ≲ 1 is not determined by the filling factor ν = nh/ eB. The position of the IQHE phases is given by the bare...
