Current distribution in Hall bars and breakdown of the quantum Hall effect
A numerical study is made of current distribution in small Hall bars with disorder. It is observed , in particular, that in the Hall-plateau regime the Hall current tends to concentrate near the sample edges while it diminishes on average in the sample interior as a consequence of localization. Also reported is another numerical experiment on a related, but rather independent topic, the breakdo...
متن کاملMultiprobe quantum spin Hall bars
We analyze electron transport in multiprobe quantum spin Hall (QSH) bars using the Büttiker formalism and draw parallels with their quantum Hall (QH) counterparts. We find that in a QSH bar the measured resistance changes upon introducing side voltage probes, in contrast to the QH case. We also study fourand six-terminal geometries and derive the expressions for the resistances. For these our a...
متن کاملTheory of the breakdown of the quantum Hall effect
Breakdown of the quantum Hall effect at high values of injected current is explained as a consequence of an abrupt formation of a metallic conduction path from one edge of the sample to the other. Such a path is formed when regions of compressible liquid, where the long-range disorder potential is screened, get connected due to the strong electric field. Our theory explains various features of ...
متن کاملCurrent Distributions in Quantum Hall Effect Devices
This paper addresses the question of how current is distributed within quantum Hall effect devices. Three types of flow patterns most often mentioned in the literature are considered. They are: (1) skipping orbits along the device periphery (which arise from elastic collisions off hard-walled potentials); (2) narrow conducting channels along the device sides (which are presumed to be generated ...
متن کاملThe quantum Hall effect
most physical phenomena that occur in nature. Its basic equation, the Schrödinger equation, accurately describes the electronic properties of solids—of great importance in modern technology.To describe the behavior of particles that travel near the speed of light, such as neutrinos, the theory must be modified to take Einstein’s theory of relativity into account. This was accomplished by physic...
