The quantum Hall effect (QHE) is one of the most prominent effects in modern solid state
physics. Since its discovery, the effect has been attracting interest by a steadily increasing …

A new effect in graphene in the presence of crossed uniform electric and magnetic fields is
predicted. Landau levels are shown to be modified in an unexpected fashion by the electric …

Nonlinear transport phenomena are an increasingly important aspect of modern
semiconductor research. This volume deals with complex nonlinear dynamics, pattern …

The quantum anomalous Hall effect (QAHE) realizes dissipationless longitudinal resistivity
and quantized Hall resistance without the need of an external magnetic field. However …

A low-temperature scanning force microscope sensitive to electrostatics is used to
investigate the potential distribution of a two-dimensional electron system (2DES) under …

The high-magnetic-field, low-temperature magnetic properties of low-dimensional electron
and hole systems reveal a wealth of fundamental information. Quantum oscillations of the …

Nonlinear transport phenomena in condensed matter reflect the geometric nature, quantum
coherence, and many-body correlation of electronic states. Electric currents in solids are …

We report on recent experimental results from transport measurements with large Hall bars
made of high-mobility G a A s/A lx Ga 1− x As heterostructures. Thermally activated …

We use dynamic scanning capacitance microscopy to image compressible and
incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in …

Breakdown of the integer quantum Hall effect (IQHE) is discussed based on the
consideration of heat stability of a two-dimensional electron gas (2DEG). First, the 2DEG …
