The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...

The Hall effect diagram in drawing "A", for example, at the beginning of the article may not be a good representation of the flow of electrons in the Hall element. It shows electrons flowing in a curved narrrow beam rather than flowing throughout the Hall element with many microscopic collisions that have electrons moving in all directions ...
Scaling of the longitudinal and Hall conductivities in a renormalization group flow-diagram of the quantum Hall effect. On the basis of the Renormalization Group Theory of the instanton vacuum one can form a general flow diagram where the topological sectors are represented by attractive fixed points. When scaling the effective system to larger ...
Differential Hall Effect Metrology (DHEM) is an electrical depth profiling technique that measures all critical electrical parameters (resistivity, mobility and carriers) through an electrically active material at sub-nanometer depth resolution. [1] [2] DHEM is based on the previously developed Differential Hall Effect (DHE) method. [3]
Hall effect magnetometers (also called tesla meters or gauss meters) use a Hall probe [23] with a Hall element to measure magnetic fields or inspect materials (such as tubing or pipelines) using the principles of magnetic flux leakage. A Hall probe is a device that uses a calibrated Hall effect sensor to directly measure the strength of a ...

The fractional quantum Hall effect (FQHE) is a collective behavior in a 2D system of electrons. In particular magnetic fields, the electron gas condenses into a remarkable liquid state, which is very delicate, requiring high quality material with a low carrier concentration, and extremely low temperatures.
